Abstract

The genus Anisoderomorpha Arrow, 1925 (Coleoptera: Erotylidae: Languriinae) is redescribed and two new species of Anisoderomorpha are described: A. tamdaoensis sp. nov. from Vietnam and A. malayana sp. nov. from Malaysia. The adults of A. tamdaoensis sp. nov. were found to be sexually dimorphic in external morphology, particularly in the shape of the head and mandibles: females have a large asymmetrical head and mandibles, whereas males have a symmetrical head with slightly asymmetrical mandibles. All three members of Anisoderomorpha and its related taxon, Celolanguria curvipes Arrow, 1925, are illustrated and the host plant of Anisoderomorpha is predicted based on the morphological similarity of the specified mouthparts to those of other genera.
