Namibdrilus Kundrata & Packova, 2024, gen. nov.

GenusNamibdrilusgen. nov. Figs 1, 2, 3, 4 Type species. Namibdrilus albertalleni sp. nov.; here designated. Etymology. The generic name is derived from the Republic of Namibia, plus Drilus, a genus name in Elateridae: Drilini. Gender: masculine. Diagnosis. Namibdrilus gen. nov. can be unequivocally distinguished from its congeners by the robust unidentate mandibles (Fig. 2 A – D) and the aedeagal median lobe dorsally without a subapical hook (Fig. 4 B, E – G). Additionally, the following combination of characters can be used to recognize the genus: body (Fig. 1 A, B) elongate; frontoclypeal region (Fig. 2 A – D) strongly produced forwards, gradually narrowed toward apex, apically carinate and widely rounded; eyes (Fig. 2 A – D) large, their frontal separation 1.15 times eye diameter; antenna (Fig. 2 E) robust, strongly serrate; pronotum (Fig. 3 A, B) roughly subrectangular, 1.30 times as wide as long, lateral carina not developed; prosternum (Fig. 3 C) distinctly transverse, without well-developed prosternal process; scutellar shield (Fig. 3 A) apically subtruncate and medially emarginate; mesoventrite (Fig. 3 C) narrow, v-shaped; elytra (Figs 1 A, 3 E) elongate, with relatively rough surface and without any apparent striae or rows of punctures; abdomen (Figs 1 B, 4 A) with eight free visible sternites, the first of which is partly membranous medially; abdominal sternite IX and tergite X (Figs 4 C, D) not apparently elongate, about 1.5 times as long as wide. Based on its morphology, Namibdrilus gen. nov. is similar to genera of the clade D (Drilus clade) defined by Kundrata and Bocak (2019).
