New data and records are reported for Chaetogramma caudata (De Santis) and Probrachista nepalensis Viggiani.

The family Trichogrammatidae (Hymenoptera: Chalcidoidea) includes internal egg parasitoids of several orders of insects, mostly Hemiptera, Coleoptera, Lepidoptera and Diptera. Although widely distributed, their small size (from about 0.2 mm to 1.5 mm) and fragility make their collecting and study difficult. At present about 100 genera are recognized, including 1006 valid species (Noyes 2019); Trichogramma Westwood (241 spp.) and Oligosita Walker (97 spp.) are the largest (Noyes 2019).

Through the courtesy of John Huber, I have received, on loan for study, the unidentified material (461 pinned specimens) of Trichogrammatidae (Hymenoptera: Chalcidoidea) deposited in the Canadian National Collection of Insects, Ottawa, Canada. The study of this valuable material revealed undescribed taxa and interesting new records, reported in the present paper.

The specimens studied were slide-mounted in Canada balsam phenol, but some of them were kept and examined also on pin cards. All the material was examined under a Leica stereoscope and a Zeiss Axiophot with phase contrast. Both instruments were used also to take pictures by a Canon Powershot 545. The nomenclature follows Doutt & Viggiani (1968) and Pinto (2006). The following terms and acronyms are used:

All type material of the new species described in this paper will be deposited in the Canadian National Collection of Insects, Ottawa, Canada.

Adryas Pinto and Owen, 2004

The genus Adryas includes 11 species (Noyes 2019), characterized by a female antenna without funicle, with 3-5 segmented club, but never with 5 segments completely separated; fore wing with MV and PM confluent. Species currently described are distributed in the Central and South American tropics.

(Figs 1-2)

Diagnosis. Antenna with club very short, 1.3×.as long as wide, with 5 asymmetrical segments, C5 as long as C2 with a subtrapezoidal profile, slightly longer than wide (20:18) and apically with a subcylindrical end, bearing a seta three times longer; distal margin of the last segment, just below the apical seta, with a patch of about 16 RS, as long as C5. Fore wing 1.9× as long as wide, PM slightly wider than the distal end of MV, about twice as long as wide and bearing 2 rather long setae, MV with 4 marginal main setae; disc moderately setose with about 18 setal tracks and several scattered setae mostly at beginning of discal ciliation; ovipositor short, slight longer than hind tibia (50:45), inserted at the middle of gaster and not extruded.

Description. Female. Body dark brown, legs with the two basal tarsomeres light yellow; fore wing with brownish veins and dusky behind venation, except a lighter area behind PM and base of MV. Length: 0.8 mm. Maxillary palp about 3 times as long as wide, with a peg-like sensillum as long as half apical seta, inserted near the distal margin. Antenna with scape 3× as long as wide, pedicel 0.7× as long as scape, club very short, 1.3× as long as wide, with 5 asymmetrical segments, C1 transverse, 3× as wide as long, C2 slightly wider than C1 but twice longer, C3 and C4 shorter than C1, C5 as long as C2 with a subtrapezoidal profile, longer than wide (20:18) and apically with a subcylindrical end, bearing a seta 3× longer; 1, 2, 2 PLS respectively on C1,C2,C3 and 3 on C5; distal margin of the last segment, just below the apical seta, with a patch of about 16 RS, as long as C5. Mid lobe of mesoscutum and scutellum each with 2 pairs of setae, and surface with a sculpture of subpolygonal cells, rather transversely oriented to the mid line of the sclerite; propodeal disc sutrapezoidal. Fore wing 1.9× as long as wide, ratios PM, MV, SV, 18:23:16, PM slightly wider than the distal end of MV, about twice as long as wide and bearing 2 rather long setae, MV with 4 marginal main setae; disc moderately setose with about 18 setal tracks and several scattered setae mostly at beginning of discal ciliation, one single seta on the membrane between PM and beginning of discal ciliation, RS1 present; fringe longest setae one-eighth of the discal width. Legs normal with subequal tarsomeres and mid spur as long as basitarsomere. Gaster conic-ovate, longer than mesosoma (10:6); ovipositor short, slight longer than hind tibia (50:45), inserted at the middle of gaster and not extruded.

Taxonomic remarks. This is the first record of the genus from the Oriental region. The new species can be assigned to Group A by Pinto & Owen (2004) of the rather broad genus Adryas, for having asymmetrical antennae and a patch of recurved setae on terminal club segment. Among the four species included in this group, A. indica shows the antennae with a terminal patch of long RS as in A. plurifumosa, but differs in having distinct club features, exhibiting also differences in wing venation (MV and PM not confluent) and shape of the propodeal disc.

Etymology. Named in reference to the country where the species was collected.

Material examinated. Holotype ♀ (slide), India: Arunachal Pradesh, Etalin environs, 700 m, 28°36’56’’N, 95°53’ 21’’E, 19-25.v.2012, L. Dembický lgt.

Chaetogramma Doutt, 1975

The genus Chaetogramma is characterized by female antenna with 1-2 segmented funicle and unisegmented club. Fore wing densely setose. 6 species, recorded from Asia, Africa, North and South America, are known.

Chaetogramma (Chaetogrammina) asensillatum sp. nov. (Figs 3-4)

Diagnosis. Funicular segment transversely divided, without PLS; veins with MV 3× as long as wide, at base without a poorly sclerotized trait, light in color, same as the apex of the PM.

Description. Female. Body dark brown, fore wing hyaline, veins brown, blade below the veins infuscated, more marked below the base of the PM and the SV; first two basal tarsomeres of the legs lighter. Length: 0.6 mm. Antenna with pedicel one-third longer than funicle, the latter transversely divided in a cup-shaped F1 and a transverse F2, both without PLS; club as long as pedicel and funicle combined; distal third of the club with 3-4 PLS. Mesosoma shorter than metasoma (5:7). Mid lobe of mesoscutum and scutellum each with 2 pairs of setae, both with a faint reticulation. Propodeum short in the middle; as long as metanotum. Fore wing twice as long as wide, MV longer than PM (15:11), disc rather densely setose, with linear setal tracks RS2 and r-m indicated, RS1 not distinct, fringe short, one eight of the discal width. Gaster ovate, with ovipositor rather short, not extruded, 1.5× as long as hind tibia; hypogynium extended to the basal half of the ovipositor.

Taxonomic remarks. Most of the variations of the Chaetogramma species concern the funicle of the antenna, which can be uni-segmented, partially or completely bisegmented. The new described species belongs to the latter group as do C. hisarense Yousuf and Shafeee and C. maculata Hayat. From these species and the other known species C. asensillatum differs mostly by the shape of the two funicular segments and the absence of PLS on them. The subgenus Chaetogrammina is here recorded the first time for the New World.

Etymology. The species name refers to the lack of PLS on funicle segments.

Material examinated. Holotype ♀ (slide), USA: California, San Bernardino County, 7 mi. E Phelan, Baldy Mesa road, 16-22.v.1981, J.T.Huber lgt.

Chaetogramma caudata (De Santis, 1997)

(Figs 5-6)

Additional notes. This species was described in the new genus Brachistagrapha by De Santis (1997), subsequently synonymized with Chaetogramma Doutt by Pinto & Viggiani (2004). After the study of the typical material the Noyfollowing notes are added: antenna with funicle partially and transversally divided in two segments and with 1 PLS; fore wing with MV at base poorly sclerotized, distally enlarged as the sessile SV; ovipositor slightly exerted, 1.5× as long as hind tibia; body length 0.82 mm. This species is near C. occidentalis Doutt, from which differs mostly for the longer funicle.

Material examined. Holotype ♀ (slide), Argentina: Loreto, Misiones, R. A., 10 April 1936, A. Ogloblin lgt; paratype: 1 ♀ same data of the holotype, except 17 April 1936.

The genus Chaetostricha includes 24 species widespread, except in Central and South America (Pinto 2006; Noyes 2019). They are characterized by having antenna with 2-segmented funicle and 3-segmented antenna; front tibia with one or more spines; male genitalia simple, tubular.

(Figs 7-9)

Diagnosis. Female. Antenna with a subglobular funicle; fore wing 1.8× as long as wide; fore tibia with one prominent spine; ovipositor extending from level of middle coxae and exerted one-fourth the length of the gaster, 3.6× as long as hind tibia; hypogynium long, extending to the end of gaster.

Antenna with pedicel twice as long as funicle, the latter subglobular, with F1 discoidal, club longer than pedicel and funicle combined (20:15); club with segments of the same length and wider at level of distal part of C1. Mesosoma shorter than metasoma (7:13): midlobe of mesoscutum and scutellum each with 2 pairs of setae and striate sculpturing; metanotum and propodeum medially short. Fore wing typical of the genus, 1.8× as long as wide, MV one- third longer than PM; disc with 17 rows of setae and fringe one-eight of its width. Legs with subequal tarsomeres. Gaster conic-ovate with long ovipositor extending from the level of middle coxae, 3.6× as long as hind tibia, exerted one –fourth the length of the gaster.

Taxonomic remarks. Of the known species of Chaetostricha, only C. thanotophora Pinto is described from North America (Pinto 1990). C. brevifuniculata differs considerably from this species by the subglobular funicle, longer ovipositor and hypogynium.

Etymology. The name refers to the short funicle.

Material examined. 1 ♀ (slide), USA: California, San

Bernardino County, 7 mi. E Phelan, Baldy Mesa road, 16-22. v.1981, J. T. Huber lgt.

(Figs 10-12)

Diagnosis. Antenna with a subcylindrical funicle; fore wing 2.1× as long as wide; fore tibia with one prominent spine; ovipositor inserted at base of the gaster and exerted only one-fifth of the gaster length, 2.4× as long as hind tibia; hypogynium long, extending beyond the end of gaster.

Description. Female. Body dark brown, fore wing hyaline with faint infuscation below the veins; legs with distal part of the tibiae and tarsomeres lighter. Length: 0.9 mm. Antennal funicle subcylindrical, with F1 short, about one-third of F2; club 1.3× as long as pedicel and funicle combined. Mesosoma shorter than metasoma (10:18); mid lobe of mesoscutum and scutellum each with 2 pairs of setae and a longitudinally reticulate sculpture. Metanotum and propodeum medially short. Fore wing 2.1× as long as wide, MV twice as long as PM, discal setae rather dense, arranged in more than 17 rows not all complete and distinct. Ovipositor extending from the base of the conic gaster and exerted one-fifth of the gaster length, 2.4× as long as hind tibia, hypogynium long, extending beyond the end of gaster.

Taxonomic remarks. The new species is near C. brevifuniculata but differs by the subcylindrical funicle, longer fore wing, shorter ovipositor and hypogynium, extending beyond the end of gaster. From C. thanatophora Pinto (Pinto 1990) the new species differs for having one prominent spine on front tibia (3-5 in C. thanatophora), hypogynium long, extending beyond the end of gaster (in C. thanatophora relatively short, extending about half abdominal length). The comparison of the new described species C. brevifuniculata and C. huberi with most of the Palaearctic species is at present unfeasible because their poor description and availability of type material.

Etymology. The species is named after the collector J. T. Huber.

Mid lobe of mesoscutum and scutellum each with 2 pairs of setae and with a longitudinally reticulate sculpture; placoid sensilla on scutellum located at about middle level between the two pairs of setae. Metanotum and propodeum medially short. Fore wing large, 1.6× as long as wide, MV short and subtriangular, shorter than PM (9:13), SV rather narrow, subrectangular, as long as the distal width of the MV; setae on the disc arranged in 18 rows well differentiated by bare interspaces. Metasoma slightly longer than mesosoma.

Body yellow, with brown sides of pronotum and propodeum; one dark brown stripe on each of the basal three abdominal segments, same colour of the subsequent tergites; antennae brownish as legs, except parts of tibiae and tarsi lighter: fore wing with brownish veins and disc faintly infumated. Length: 0.7 mm. Antenna with scape 3× as long as wide, pedicel shorter twice as long as wide, F1 very short, ring-like, club with segments progressively slender, C1 1.8× as long as wide, widest of the club segments, C2 as long as C1, 3.7× as long as wide, C3, the longest club segment, 6.2× as long as wide, apparently distinct in a basal part 1.5× longer than the distal part, the latter ending with two prominent sensilla forming like a fork; 4, 3, 2 PLS respectively on one surface of the club segments. Mid lobe of mesoscutum and scutellum each with one pair of setae, long as the length of last sclerite. Metanotum and propodeum very narrow in the middle.

Taxonomic remarks. Among the five species of Hydrophylita described (Noyes 2019) the new species is close to H. emporos Shih & Polaszek (Shih et al. 2013) for having the two last club segments completely fused and other characters. However, H. pacifica shows fore wing shorter, with markedly different ciliation, F1 and F2 subequal, C1 longer than F2.

Etymology. The specific name refers to the Pacific Ocean where the collected place is located.

Fore wing rather broad, 1.9× as long as wide, venation with PM arched to the MV with an enlarged base shaped like the stigma of the SV; RS1 absent; Cu2 strongly curved from the level of the SV to the base of the PM, disc sparsely setose, longest fringe setae, one-fourth of the discal width. Gaster conic-ovate, ovipositor extending from the middle of gaster and extruded, 2.2× as long as hind tibia, 3V very narrow, 15 times as long as wide.

Male. Similar to female. Antenna with club distinctly 5-segmented, all club segments with whorls of FS, the longest as C3 and C4 combined.

Taxonomic remarks. The new genus appears unique for the combination of female and male antennae, fore wing venation and male genitalia. Based on several characters (maxillary palp, setae on midlobe of mesoscutum, scutellum and male genitalia), Indonesiagramma is assigned to the tribe Trichogrammatini. The shape of the female antennal club of the new genus recalls that of Kyuwia Pinto & George, a genus recorded from Subsaharan Africa (Pinto & George 2004), included in the tribe Chaetostrichini, which species have fore wing, male antenna and genitalia markedly different. For fore wing shape and venation Indonesiagramma recalls some species of Adryas Pinto & Owen, another genus assigned to the Chaetostrichini.

Etymology. The name of the genus refers to the country where the specimens were collected and that of the species to the shape of the wing venation.

Male as the female; genitalia simple, without genital capsule, parameres and volsellae, as in Oligositini.

(Figs. 60-65)

Diagnosis. Female antenna rather short, with scape a little longer than pedicel (12:10), club twice as long as pedicel, with C1 very short, transverse, one third of C2, the latter half of the conical C3.Fore wing 3× as long as wide, with long venation, PM collinear with the MV, both combined 5× the elongate SV; base of the PM enlarged; disc mostly bare, fringe longest setae 0.8× the discal width. Propodeum in the middle with a shield- like dorsellum. Gaster ovate, ovipositor inserted near its middle, slightly exerted, 1.3× as long as hind tibia. Male genitalia simple, without genital capsule, parameres and volsellae, as in Oligositini.

Description. Female. Body dark brown, fore wing with a marked infumation from below PM to SV; legs with extremity of the tibiae and first two tarsomeres lighter. Length: 0.6 mm. Antenna rather short, with scape a little longer than pedicel (12:10), club twice as long as pedicel, slightly wider than the latter, with C1 very short, transverse, one-third of C2, C3 conical, twice of C2; C2 and C3 with 1-2 PLS extended externally and a few FS. Maxillary palp one-segmented. Mid lobe of mesoscutum and scutellum each with one pair of setae; placoid sensilla on scutellum, internally near the base of the setae; sculpture not clearly marked. Fore wing 3× as long as wide, with long venation, PM collinear with the MV, both combined 5× length of the elongate SV; base of the PM enlarged; costal cell extremely reduced and without setae; disc mostly bare, RS1 not present, with a row of setae along the distal half of the anterior margin and other sparse cilia at level of r-m and M tracks; a group of microsetae is present near the discal hind margin about midway between level of base of PM and SV; fringe longest setae 0.8× the discal width. Metanotum medially very short and propodeum in the middle with a shield- like dorsellum. Legs normal with tibial spur of the middle leg slightly shorter than basitarsomere. Gaster rather round, ovipositor inserted near its middle, slightly exerted, 1.3× as long as hind tibia.

Male. Similar to the female, but antenna with C3 as long as C2, and distally with 3 long setae, each of the mentioned segments with PLS not markedly extended externally; genitalia simple, without genital capsule, parameres and volsellae, as in Oligositini, 4× as long as wide, basally truncate and externally angled and more sclerotized, length 0.06 mm.

Taxonomic remarks. The new genus shares some characters, mainly wing venation, with Adryas Pinto & Owen (2004), at present including 11 species, known from Central and South America. Tentatively this genus was placed in the subtribe Chaetostrichini, but some of the species, namely A. bochica Pinto & Owen and A. iris Pinto & Owen, have mid lobe of mesoscutum with one pair of setae, as in Oligositini. This complex appears rather varied, mostly for antenna and fore wing characteristics; probably when more information will be accumulated, in particular on the male genitalia, a rearrangement may be evaluated. The new genus Masnerigramma clearly is to be included in the Oligositini for several characters (one pair of setae on mid lobe of mesoscutum and scutellum and type of male genitalia).

Etymology. The genus name is referred to the collector L. Masner and that of the species to the country where the species was collected.

The new species, which is assigned to the collina group, shares with the Nearctic species O. americana Girault (Viggiani 1981) the long ovipositor, but the latter species has a shorter club (3 times as long as wide), normal discal setae, longest fringe setae about 0.5× as long as discal width, and different body coloration.

Etymology. The name refers to the short setae on the fore wing disc.

Probrachista Viggiani, 1968

The genus includes 2 species, P. nepalensis Viggiani from Nepal and P. bharatensis Hayat from India (Noyes 2019). In the first species, type of the genus, the antenna shows one funicular segment and the club three-segmented, but C1 is slightly dissociated from C2, appearing somewhat funicle-like, with the ovipositor considerably exerted. The second species has a compact 3-segmented antennal club and not exerted ovipositor.

(Figs 76-77)

Diagnosis. Antenna with club 2-segmented, with a few long setae, fore wing 2.2× as long as wide, disc densely setose, from the level of the SV and with a short bare area around the mentioned vein, longest fringe setae onefifth of the discal width. Gaster conic-ovate, longer than mesosoma (7:4), with ridged tergites, ovipositor extended from the middle of gaster, not exerted, 1.3× as long as hind tibia.

Description. Female. Body dark brown, fore wing completely infumated. Length: 0.4 mm. Head with rather long setae on vertex; maxillary palp one-segmented. Antenna with short scape, about twice as long as wide, as long as pedicel, funicular segment slightly longer than wide (10:8), club 5× as long as wide, two-segmented, C1 and C2 subequal in length, each with a few setae, the longest as long as C2 or slightly longer and with 1-2 PLS, last segmented showing a pointed rod-like sensillum, 0.6× as long as C2. Mid lobe of mesoscutum and scutellum each with one pair of setae and with a ridged sculpture. Fore wing 2.2× as long as wide, MV and PM directly confluent, and combined, 5× as long as SV, the latter with a short basal constriction and orthogonally oriented to the anterior wing margin, disc densely setose, from the level of the SV, with a short bare area around the mentioned vein, longest fringe setae one-fifth of the discal width. Metanotum very narrow in the middle, about half of propodeum. Legs with tarsomeres subequal. Gaster conic-ovate, longer than mesosoma (7:4), with ridged tergites, ovipositor extended from the middle of gaster and not exerted, 1.3× as long as hind tibia.

Taxonomic remarks. P. biclavata differs from the known species mostly by the club shape.

Etymology. After the 2-segmented club.

Material examined. Holotype ♀ (on slide), Malaysia: Sabah, Danum Valley, Field Centre, 227 m, 4.96984°N, 117.80149°E, 5-10.viii.2012, J. H., A. M. & A. W. Skevington lgt.

(Figs 78-80)

Diagnosis. Fore wings faintly infumated. Legs fuscous. Antenna with a narrow 3-segmented club, all club segments with only long setae, at most as long as last segment. Fore wing with longest fringe setae one-third of discal width. Ovipositor extended from the base of gaster and exserted 0.7× the length of the same, 2.7× as long as hind tibia.

Description. Female. Body dark brown, antennae light brown, legs fuscous, and gaster lighter with brown basal band on each tergite, fore wing rather slightly infumated. Length: 0.7 mm. Antenna with scape 3× times as long as wide, pedicel long, 0.7× as long as scape, both with robust setae, funicular segment slightly longer than wide, club rather narrow, 6× as long as wide, with C1 shorter (0.7) than C2, and C3 slightly longer than C2; C2 and C3 with 1-2 PLS and only long setae, at most a little longer than last segment, the latter with a terminal rod like sensillum as long as half C3. Mid lobe of mesoscutum and scutellum each with one pair of long setae, longer than scutellum, metanotum medially very short, propodeum with the distal margin in the middle sinuate and about one-third as long as scutellum. Fore wing 2.5× as long as wide, PM and MV combined 5× as long as SV, disc densely setose from the level of the SV and with a subtriangular bare area beyond the stigma and around the SV; longest fringe setae one-third of the discal with.

Gaster conic-ovate, longer than mesosoma (11:8), with ridged tergites, ovipositor extended from the base of gaster and exserted 0.7× the length of the same, 2.7× as long as hind tibia.

Taxonomic remarks. The new species shows a rather narrow 3-segmented antennal club, not compact as in P. bharatensis, but near P. nepalensis. From the latter species P. longiciliata differs mostly by the club shape and its elongate setation.

Etymology. The name refers to the long setae on the antennal club.

Material examined. Holotype ♀ (slide), Kenya: Western Kakamega, Rondo, 0°13.66’N, 34°53.12’E, 1630 m, 17-31.vii.2006, R. Copeland lgt.

Probrachista nepalensis Viggiani, 1968

(Figs 81-83)

Additional note. At present the species is known only from 3 female specimens collected in East Nepal. To the original description (Doutt & Viggiani 1968) here are added some notes based on new records of the species in Vietnam, which help in the identification of the species. As reported in the original description the antenna shows a funicle and a club both apparently 2-segmented; in fact, the first club segment is similar to the funicular segment, mostly for bearing long setae, which are numerous, but short on the subsequent club segments. This shape of antenna is unique for P. nepalensis.

Material examined. 1 ♀ (on pin card), Vietnam: Cao Bang, Phia-Oac Mts, Phia-Den environs, 800-1200 m, 22°34’01’’N, 105°52’14’’E, 30.v-7.vi.2011, E.Jendek lgt. 1♀ (on slide), Vietnam: Vihn Phue, Melhin Biodiversity Station, 80-200 m, 21°23’04’’N,105°42’44’’E, 9-12. vi.2011, E.Jendek lgt.

(Figs 84-85)

Diagnosis. Antenna with a 3-segmented club, all club segments only with long setae, at least as long as the own segment. Fore wing with longest fringe setae one- third of discal width. Ovipositor extended from the base of gaster and exserted 0.6× the length of the same, 2.3× as long as hind tibia.

Description. Female. Body dark brown, as antennae, legs and gaster, fore wing markedly infumated. Length 0.8 mm. Antenna with scape 4× as long as wide, pedicel long, 0.8× as long as scape, funicular segment slightly longer than wide, club rather narrow, 6× as long as wide, with C1 shorter than C2 (7:10), and C3 slightly longer than C2 (13:10); all club segments with 2-3 PLS, C3 with a terminal rod like sensillum; funicle and club segments all with long setae, at least as long as their own segment. Mid lobe of mesoscutum and scutellum each with one pair of long setae; metanotum medially very short, propodeum with the distal margin in the middle sinuate. Fore wing 2.2× as long as wide, PM and MV directly confluent, combined 5× as long as SV, disc densely setose from the level of the SV and with a reduced subtriangular bare area beyond the stigma and around the SV; longest fringe setae one-fourth of the discal width. Legs normal, with distal tarsomere half the length than each of the preceding segments. Gaster conic-ovate, longer than mesosoma (13:6), with ridged tergites, ovipositor extended from the base of gaster and exserted 0.6× the length of the same, 2.3× as long as hind tibia.

Taxonomic remarks. The new species shows a 3-segmented antennal club as in P. longiciliata, but differs from the latter species by the antennae shape, fore wing ciliation, and leg colour.

The genus Probrachista Viggiani was based mostly on the different antennal formula from Brachista Walker (sensu Nowicki 1936; Doutt & Viggiani 1968), including 3 Palaearctic species and one Indian species, at present under Chaetostrichella Girault (Pinto 1993). In the latter genus all species have one-segmented club. None of the new species here described in Probrachista shows this character, but one has 2-segmented club, an intermediate state between the known Probrachista and Chaetostrichella. The new findings suggest a further taxonomic evaluation of the mentioned genera and their possible inclusion in Pseudoligosita.

Etymology. The name refers to the 3-segmented club.

Material examined. Holotype ♀ (slide), Vietnam: Hue province, Back Ma Nat. Park, 16-20,iv.2012, 900-1140 m, 16°11’33’’ N, 107°50’52’’ E, E. Jendek lgt.

Fore wing with an infuscate area from the base to the SV level and with another interrupted, infuscate band between the SV and the wing distal margin. Length: 0.4 mm. Mandible with a pos terior spine, one external pointed tooth followed internally by 3 small teeth. Maxillary palp small, one-segmented. Antenna with elongate scape, twice as long as pedicel, one anellus, funicle 2-segmented, both as long as wide, club twice as long as wide, slightly shorter than scape (28:30).

Legs normal with subequal tarsomeres. Gaster conic-ovate, longer than mesosoma (6:5), ovipositor short, with base inserted in the middle of gaster, sligthly extruded, and as long as hind tibia.

Taxonomic remarks. At present one species is included in this genus, P. fasciatipenne Girault from Australia (Queensland) and illustrated by Doutt & Viggiani (1968). Unfortunately the characters described by the mentioned authors do not allow a reliable comparison, but the new species differs at least from P. fasciatipenne by the brown marking and the long fringe of the fore wing. The genus Pseudogrammina is here recorded for the first time from New Zealand.

Etymology. The species name is referred to the fore wing infuscation pattern.

Trichogramma Westwood, 1833

The genus Trichogramma Westwood, including 241 species (Noyes 2019), is the largest genus of Trichogrammatidae and certainly the most investigated. According to Pinto (2006) “the characteristic sinuate fore wing with RS1 track and 2F/1C antennal formula in females separate Trichogramma from other genera”.

Trichogramma unicum sp. nov.

(Figs 98-100)

Diagnosis. Antenna with unisegmented club, 3.6× as long as wide, with FS at most one-third longer than the maximum club width. Genitalia with genital capsule 1.4× as long as wide, antero-dorsal aperture twice as long as wide, distal lamina well developed and subdiscoidal, intervolsellar process present; parameres very narrow, curved, seta- like; volsellae elongate about 4× as long as wide, without digital spines; aedeagus with body rather short, slightly longer than the apodemes, distally pointed.

Description. Male. Body brown; head with yellowish vertex. Length: 0.5 mm. Mandible distally trunked with five marginal small teeth and on the internal margin, subapically, with a socked tooth. Maxillary palp twice as long as wide, with an apical seta slightly longer than the palpus length and one spiniform sensillum about as long as the palpal length. Antenna with a short radicle, as long as wide, scape twice as long as pedicel, one anellus, club unisegmented, 3.6× as long as wide, with FS at most onethird longer than the maximum club width. Ratios head, mesosoma, metasoma length: 3.5:5:7. Mid lobe of mesoscutum subtrapezoidal, with a reticulate sculpturing and two pairs of setae, twice as long as scutellum. Metanotum and propodeum very short medially. Wings lacking. Tegula of the fore wing with one seta. Genitalia, length 0.13 mm, genital capsule 1.4× as long as wide with anterodorsal aperture twice as long as wide, distal lamina well developed, subdiscal, intervolsellar process present; parameres very narrow, curved seta-like; volsellae elongate about 4 times as long as wide, without digital spines; aedeagus with body rather short, slightly longer than the apodemes, distally pointed.

Taxonomic remarks. The apterous new species, described on a male, is assigned to the genus Trichogramma on the basis of shared characteristics of mandibles, antennae and male genitalia, but the latter appear unique for the shape of the dorsal lamina, parameres and volsellar digiti. For some characters (distal enlarged dorsal lamina, in dorsal view concealing parameres and volsellae) T. unicum may be tentatively placed in the drepanophorum group of Trichogramma (Pinto & Oatman 1996). Once the female and/or the winged male will be discovered the present taxonomic placement can be reconsidered.

Etymology. The species name is referred to the unique features of the male genitalia.

Material examined. Holotype ♂ (slide), New Zealand: South Island, Craigieburn Forest Park, 829 m, 2-4.iii.2009, 43°08’33’’S, 171°44’21’’E, H. Goulet lgt.

The findings reported in the present paper widen the geographical distribution of several genera and species of Trichogrammatidae. A representative of the genus Adryas is firstly recorded from the Oriental region and species of Hayatia and Probrachista from Africa. Interesting new data concern the delimitation of some genera as Pseudoligosita and Probrachista, taking into account the variations of the antennal formula. After more than one century the genus Pseudogrammina, known only from Australia, is recorded from New Zealand. A wider knowledge is done on the poorly known genus Haeckeliania, one of the largest genera of Trichogrammatidae with the vast majority of species, including many from the New World, awaiting description (Pinto 2006).

The ten new species of the genus, described in the present paper, confirm this view and point out the remarkable interspecific variations concerning particularly the antennal shape and sensilla, and the fore wing venation in these small insects.
