Comments. The species was described in the genus Aenidea , which was later synonymized with Palpoxena and therefore recent authors classified A. sumatrensis in Palpoxena (e.g., WILCOX 1973, KIMOTO 1990, MOHAMEDSAID 1995b, MOHAMEDSAID & FURTH 2011). The examination of the type specimens showed that males have a metasternal process and therefore Aenidea sumatrensis is transferred to Taumacera . Ozomena intermedia was described from an unknown number of specimens, presumably females as no male sexual characters were mentioned in the description ( JACOBY 1899). The comparison of the specimens (both males and females) of Aenidea sumatrensis and Ozomena intermedia showed no difference. The colouration of the female antennae is variable. In the darkest specimens (including the syntype of Ozomena intermedia ) the antennomeres VIII–X are yellow while all remaining antennomeres are contrastingly black. Ozomena intermedia is proposed as a new synonym of Taumacera sumatrensis .
