Distribution. India, Nepal.

Redescription. Male ( Figs. 1‒2 View FIGURES 1 ‒ 4 ). Head black, reddish brown on middle line of vertex, mouthparts light yellow, more or less lightened at maxillary and labial palpi, dark brown at apices of mandibles, antennae black, light yellow at apex of each antennomere, pronotum dark brown, slightly lightened at lateral margins, scutellum light yellow, elytra light yellow and mottled with irregular dark brown markings, legs light yellow, darkened at apices of femora and tarsomeres and bases of tibiae and coxae, more or less darkened at outer sides of femora and outer and dorsal sides of tibiae, prosternum light yellow, meso- and metasterna and abdominal ventrites black brown, light yellow at posterior margins of abdominal ventrites and the whole terminal ventrite. Body densely covered with light yellow pubescence, mixed with slightly long, semirecumbent light yellow pubescence and erect black brown setae on elytra.

Head subquadrate, temples straight and slightly converging posteriorly, dorsum slightly convex in central part, surface semilustrous, densely and finely punctate, each side with a smooth and rectangular impression behind antennal socket; eyes strongly protruding, head width across eyes slightly narrower than pronotum; terminal maxillary palpomeres long-triangular, widest at basal one-third, with apical parts of inner margins arcuate and sharp, acute at apices; antennae extending to basal two-thirds length of elytra, antennomeres II about twice as long as wide at apices, III slightly longer than II, IV longest, from V to XI gradually shortened, XI pointed at apex.

Pronotum about 1.18 times as wide as long, widest nearly at posterior one-third, anterior margin rounded, lateral margins sinuate, posterior margin arcuate and narrowly bordered, anterior angles rounded, posterior angles sharp, protruding, disc distinctly convex on posterolateral parts, surface lustrous, finely and sparsely punctate.

Elytral length about 5 times length of pronotum, 3 times as long as humeral width, with lateral margins slightly diverging posteriorly, surface semilustrous, rugulose-lacunose and finely punctate.

Aedeagus ( Figs. 21‒23 View FIGURES 21 ‒ 23 ): ventral process of each paramere bent ventrally about 90 degrees, with the bent portion at apical part nearly as long as the basal portion, slightly thickened terminally, slightly concaved on upper margin and circular at apex in lateral view, dorsal plate distinctly shorter than ventral process ( Fig. 22 View FIGURES 21 ‒ 23 a), evenly narrowed apically, rounded at apex ( Fig. 23 View FIGURES 21 ‒ 23 a), laterophyse rounded at apex.

Female. Similar to the male, but head slightly convex on dorsum, head width across eyes distinctly narrower than pronotum, antennae shorter and extending to elytral midlength, pronotum moderately convex on posterolateral parts of disc, elytra with lateral margins distinctly diverging posteriorly, abdominal sternite VIII (Fig. 11) abruptly narrowed posteriorly, nearly parallel-sided on posterior part, longitudinally convex in middle of sclerotized part, the convex narrowed anteriorly and triangular at base, with lateral margins nearly membranous, posterior margin roundly emarginated in middle, lateroapical angles rounded, the lobe moderately sclerotized, nearly triangular and divided in middle of posterior part.

Body length: 8.0‒10.0 mm; width: 2.0‒ 2.2 mm.

Remarks. Although the aedeagus of this species was illustrated, and some comments made by Wittmer (1974) and Švihla (2005) respectively, its morphological characters are quite poorly known, except the simple original description by Bourgeois (1902). In this study, examination of the types and some additional specimens allows us to redescribe and illustrate this species here. This species was recorded as occurring in Nepal by Okushima (1999), but that distribution data is not repeated here because of a possible misidentification in the latter study.
