Species delimitation by a geometric morphometric analysis within the genus <em>Pseudoathyreus</em> and description of a new species (Coleoptera: Scarabaeoidea: Bolboceratidae)
Keywords:Morphology, biometry, taxonomy, biogeography, arid environments
A geometric morphometric analysis, conducted as part of a taxonomic review of the genus Pseudoathyreus (Coleoptera: Bolboceratidae), allowed us to highlight the differences within a group of closely related species spread from the Sahel region to India, supporting the traditional morphological approach and confirming the presence of a newly discovered species (P. zianii n. sp.).
