Description. Length 4.0– 4.7 mm, width 1.6–2.8 mm. General color yellow, with one pair of black spots on vertex ( Fig. 9View FIGURE 9 C); some individuals with vertex totally black ( Fig. 9View FIGURE 9 D); some females with black or blackish brown elytra ( Fig. 9View FIGURE 9 E). First antennomere swollen in male ( Fig. 11View FIGURE 11 A), length ratios of antennomeres I –XI 1.0: 0.4: 0.6: 0.6: 0.7: 0.7: 0.7: 0.7: 0.7: 0.6: 0.8, length to width ratios of antennomeres I –XI 2.5: 1.7: 2.5: 3.3: 3.6: 3.5: 3.6: 3.6: 3.6: 3.3: 4.3; first antennomere more slender in female ( Fig. 11View FIGURE 11 B), length ratios of antennomeres I –XI 1.0: 0.4: 0.7: 0.7: 0.7: 0.7: 0.8: 0.8: 0.7: 0.7: 0.9, length to width ratios of antennomeres I –XI 3.9: 2.0: 3.5: 3.6: 3.8: 3.7: 3.9: 3.9: 3.7: 3.7: 4.6. Elytra 1.9 x longer than wide, surface with erect, yellowish brown, dense, elongate setae; and fine punctures. Apical margin of last abdominal ventrites with two shallow incisions in males ( Fig. 11View FIGURE 11 G); medially depressed in females ( Fig. 11View FIGURE 11 H). Penis ( Figs 11View FIGURE 11 C –11D) slender, gradually narrowed towards apex; apex of dorsal surface with deep notch; apex of ventral surface slightly medially depressed; almost straight in lateral view, apex with deep notch between dorsal and ventral surface; ventral surface smooth. Internal sac covered with dense short setae; median endophallic spiculae long, about 0.5 x as long as penis, apex trilobed, median lobe medially swollen, with dense lateral setae subapically, lateral lobes slender; one pair of dorsal spiculae at middle, anteriorly extending near apex of median spiculae; three pairs of basal spiculae horn-like, basal pair longest, other pairs shortened; one pair of ventral speculae straight, located from base to midpoint. Gonocoxae ( Fig. 11View FIGURE 11 E) extremely slender, 8.2 x longer than wide, briefly contiguous at middle, sides narrowed at apical 1/10; apices narrowly rounded; inner margins approximate from apex to midpoint, apex with nine setae; slender from midpoint to base but abruptly widened at base. Ventrite VIII ( Fig. 11View FIGURE 11 F) well sclerotized; spiculum elongate; apex square, apical margin truncate, with dense short setae; disc with several elongate setae at sides. Receptacle of spermatheca ( Fig. 11View FIGURE 11 I) strongly swollen, distinctly separated from pump; pump strongly curved, apically tapering; proximal spermathecal duct slender, distinctly narrower than receptacle, basally widened, shallowly projecting into receptaculum.

Differential diagnosis. Doryscus nepalensis  sp. nov. adults can be separated from those of D. niger  based on the following combination of characters: strongly swollen antennomere I in male, relatively slender antenna, and yellow pronotum.

Etymology. This new species is named for its type locality.

Remarks. Specimens identified as Doryscus testaceus  by Kimoto and Takizwa are deposited at the SEHU and available for study. They are attributed to this new species.

Distribution. Bhutan, India, Nepal.
