Diagnosis.

Dorsum black. PW/PL = 1.02-1.07; PAW/PBW = 0.98-1.00 (Fig. 20 View Figures 17–24 ); pronotum subquadrate with anterior angles rounded, slightly projected forward; disc densely and completely rugose, punctate. Elytral intervals flat and densely punctate and pubescent. Hind wings reduced. Metepisterna short, MW/ML = 1.3-1.4 (Fig. 13 View Figures 11–16 ). Apical lamella of median lobe truncated, right side with a large denticulation, left side with a small denticulation (Fig. 28A-E View Figures 28–30 ), sometimes, such denticulation absent.

Description.

BL = 19.6-21.9 mm, BW = 7.3-7.6 mm, PAW = 3.33-3.55 mm, PBW = 3.40-3.55 mm, PW = 4.35-4.55 mm, PL = 4.05-4.45 mm, MW = 1.65-1.80 mm, ML = 1.20-1.35 mm. Head, pronotum, elytra, legs, and venter black; antennae, labial and maxillary palpi, apex of mouthparts and tarsomeres dark brown.

Head. Vertex punctate and pubescent with a rugose area; antennae long, reaching middle of elytra; antennomere 3 ~ 1.5 × longer than antennomere 4.

Pronotum subquadrate, PW/PL = 1.02-1.07 (Fig. 20 View Figures 17–24 ), widest at apical third; anterior margin slightly concave, its width equal to width of basal margin, PAW/PBW = 0.98-1.00; lateral margins slightly bent before middle, then gently narrowed to base, straight before posterior angles; anterior angles rounded, slightly projected forward; posterior angles right angled, slightly rounded at tips; disc gently convex, sparsely punctate, pubescent, with a few transverse rugosities, without glabrous area in the middle; median line distinct, deep, reaching anterior margin and base; basal foveae deep, short, broad, punctate, and pubescent.

Elytra elongate, EL/BW = 1.64-1.77; gently convex near anterior third, widest near posterior third, rounded at apex in males; striae with deep punctures; parascutellar striae well developed; parascutellar pores present; intervals flat, densely punctate and pubescent; sutural angles sharp; hind wings reduced.

Venter densely punctate, pubescent, metepisterna (Fig. 13 View Figures 11–16 ) short, MW/ML = 1.30-1.38; abdominal sternites III-VI with one setiferous puncture each side, sternite VII with one pair of setiferous punctures in males, two pairs in females; all abdominal sternites with distinct impressions laterally.

Legs long and slender; tarsi nearly smooth dorsally.

Male genitalia. Median lobe (Fig. 28B-E View Figures 28–30 ) stout, strongly bent to ventral side; apical orifice opening dorsally, long and wide, not reaching basal bulb; in dorsal view, apical lamella (Fig. 28A View Figures 28–30 ) wide and short, wider than long, apex truncated; in left lateral view, apical right side with a large denticulation towards the base and outside, basal left side only thickened and convex or convex into a small denticulation, basal orifice ~ 90 ° relative to preapical shaft; left paramere large and round; right paramere helically curved; endophallus with flagellum coiled; basal part of flagellum with a disciform sclerite facing the right; apical part of flagellum with strip of sclerite.

Female genitalia unknown.

Distribution.

China (Yunnan), Vietnam.

Remarks.

The type locality is situated in the mountains of the Black River, northern Vietnam, not far from the Chinese frontier. Our identification is based on the original description and illustration of the male genitalia of the holotype by Casale (1984: 379, figs 11, 13).
