Abstract

After the description of Ascalaphus (Haploglenius) obscurus Westwood, 1847, the type specimen was lost. Thus, the genus and subfamily classification of the species became uncertain. Later taxonomists (Hagen 1866, McLachlan 1873, van der Weele 1909) could not clarify the correct combination of the genus (Haploglenius, Idricerus). Tauber et al. (2019) found the syntype of the species, this solved a number of nomenclatural and taxonomic problems. Ascalaphus (Haploglenius) obscurus Westwood, 1847 is moved to Protidricerus obscurus (Westwood, 1847) (comb. n.) and the lectotype is designated. Protidricerus philippinensis Esben-Petersen, 1927 (syn. n.) is a junior synonym of Protidricerus obscurus (Westwood, 1847). Instead of Ascalaphus (Haploglenius) obscurus Westwood, 1847, Stylascalaphus fabiani Mészáros & Ábrahám, 2005 is designated to type species (present designation) of Stylascalaphus Sziráki, 1998. Mansellacsa longicornis Hölzel, 2004 (syn. n.) is a junior synonym of Stylascalaphus krueperi (van der Weele, 1909).
