Review of Eudyasmus, with descriptions of a new species from Waigeo Island, Indonesia and a closely related new genus (Curculionidae: Molytinae: Eudyasmini)

Abstract

Eudyasmus Pascoe, 1885 (Curculionidae: Molytinae: Eudyasmini), an endemic weevil genus from New Guinea, is reviewed. The genus is redescribed, all previously described species are diagnosed, and lectotypes are designated for three species. Prior to this study, Eudyasmus was only known from Papua New Guinea but is reported here for the first time from the Indonesian part of New Guinea based on the description of Eudyasmus basalis Pancini & Bramanti sp. nov. from Waigeo Island, West Papua Province. A new genus, Protrachyasmus Setliff gen. nov., is described to accommodate Eudyasmus planidorsis Heller, which is non-congeneric with the four remaining Eudyasmus species. A species level identification key, distribution map, and illustrations are provided for all species of these two closely related genera.
