Re-description. Body length 3.5–6.6 mm. Coloration pale, brownish- or reddish-yellow; body integument dull or with slight oily shine, with moderately dense, decumbent and nearly inconspicuous yellowish setae.
Head 0.75–0.80 times as wide as pronotum; integument with more or less dense granulation. Distance between inner edges of antennal insertions less than 0.35 times as great as that between mandibular bases (Fig. 18). Eyes moderately large, slightly convex (Figs 18, 43).
Antennae comparatively long and nearly filiform (Figs 36–38), reaching posterior quarter of pronotum. Antennomere 3 elongate, slightly thickened apically, 1.6–1.7 times as long as wide and 1.3–1.4 times as long as antennomere 4; antennomeres 4–8 subequal, slightly elongate and moderately thickened apically, 1.2–1.3 times as long as wide; antennomeres 9–10 moderately thickened apically, 1.25–1.35 times as long as wide. Antennomere 11 1.3–1.4 times as long as antennomere 10. Orifices of sensory cavities of antennomeres 9–11 small, transversely oval (Fig. 39).
Pronotum 1.10–1.20 times as wide as long at midline, widest before middle, sides weakly convex and slightly sinuate at posterior angles; disc subflattened, with median groove in posterior half or third. Lateral carinae complete and slightly bent anteriorly (Fig. 43). Posterior angles slightly divergent, obliquely truncate at apex. Integument with granules moderately dense at middle and becoming denser and more prominent towards sides and apex; interspaces between granules at middle 1–3 times as wide as granules. Prosternum and hypomera covered with granules finer than those on pronotum, sometimes obliterated at middle; interspaces between granules 2–4 times as wide as granules.
Elytra 2.15–2.35 times as long as wide combined and 2.75–2.90 times as long as pronotum. Elytral striae moderately impressed, with strong, coarse and moderately dense punctures. Interstriae subequal, slightly convex to nearly flat; integument with sparse granulation, interspaces between granules 1–3 times as wide as granules. Metaventrite with granules finer and about as dense as those on prosternum.
Legs moderately long; tarsi long and moderately slender; metatarsus about 0.9 times as long as metatibia (Figs 54, 55).
Abdominal ventrites covered with granules very fine and sparse, sometimes obliterated at middle, becoming denser on ventrite 5; interspaces between granules at middle 3–6 times as wide as granules.
Male. Ventrite 5 as in Fig. 62. Tergite VII (pygidium) semielliptical, widely rounded at apex (Fig. 67). Sternite 9 emarginate at apex (Fig. 68). Aedeagus as in Figs 86–92.
Female. Ventrite 5 as in Fig. 63. Abdominal segment VIII as in Fig. 96; sclerites of sternite VIII comparatively small and lightly sclerotized (Fig. 96).
Distribution. Afghanistan (Muona 2007), India (Karnataka, West Bengal), Myanmar, Cambodia.
