Diagnosis: This species is rather distinct in Dima species by the following combination of characters: pronotum strongly convex from lateral view; mesoventrite and mesanepisternum with relatively small procoxal rests; elytral base narrowed; punctures on elytra conspicuously enlarged, interstria VI forming a prominent ridge; male genitalia with median lobe robust, much longer than parameres, with numerous minute spines on the ventral surface. D. xiaolongi Ruan, Kundrata & Qiu sp. nov. resembles the most D. tianmuensis from Zhejiang, China (Qiu et al. 2018). Both species share similar habitus, coloration, general shape of pronotum and mesoventrite, and ventrally serrate median lobe. However, D. xiaolongi Ruan, Kundrata & Qiu sp. nov. has denser pronotal punctation, longer posterior pronotal angles, more transverse metacoxal plate, median lobe relatively longer with respect to paramere, without basal struts, and differently shaped hook-like structures on paramere (Figs 4 A–D, 5C– D). D. xiaolongi Ruan, Kundrata & Qiu sp. nov. also resembles D. guizhouensis Ruan, Kundrata & Qiu sp. nov. in the relatively long elytra with ridge-like interstria VI. However, it can be easily distinguished from the latter by the chestnut brown coloration and divergent posterior pronotal angles.

Selasia dembickyi sp. nov. is the only Drilini species known from South East Asia. It can be recognized by the following combination of characters: head and pronotum lighter than rest of body (Figs 1–2), weakly flabellate antennae (Fig. 5), strongly sinuate pronotal sides with distinctly diverging posterior angles (Fig. 7), and base of sternite IX not emarginate (Fig. 9). This species has uniquely shaped male genitalia among Drilini (Figs 12–13) with a very long and narrow median lobe, which is distinctly longer than the parameres, elongate parameres which are widest at the second third, and the phallobase which is short compared to the median lobe and parameres. Etymology. The specific epithet is a patronym in honor of Luboš Dembický (Brno, Czech Republic), the collector of the holotype. Collecting circumstances. Members of Selasia are usually collected at light or using Malaise traps (e.g., WITTMER 1989; KUNDRATA 2012a, 2017; TRLLOVA & KUNDRATA 2015). The exact collecting circumstances for S. dembickyi sp. nov. are not known but it was most probably collected at light or using a flight interception trap (L. Dembický, personal communication). The habitat of this species is shown in Figs 18–19. Distribution.
