Description. Male. Head and pronotum black without metallic lustre, clypeus, mandibles, genae and anterior side of labrum, left and right sides of mouthparts, including 2nd and basal 4/5 of 3rd segments of palpi, basal half of antennae, tibiae and 1st–4th tarsomeres, anterior and intermediate trochanters yellow. Elytra and scutellum black with green-violet metallic lustre. Femora dark brown, lacking metallic lustre. Ventral side of thorax, coxae and abdomen black; middle of mouthparts, borders of sternites and thoracic mesepimera brown, vesicles yellow.
Head slightly narrower than pronotum, distinctly impressed just before clypeus, with a thin longitudinal carina in middle of basal part of the disc; sparsely covered with thin, short, semi-erect light pubescence; presence of long black erect setae: several on temples behind eyes, a few on the head sides and a row on distal margin of clypeus; surface shining, coarsely punctate with indistinct microsculpture, wrinkled on temple near carina; labrum short, transverse, bearing long semi-erect white hairs; genae short, straight; eyes protruding, round. Maxillary palpi short, 1st segment large, triangular, half the length of, and narrower than, the 3rd; 2nd very small, transverse; apical one securiform, twice as long as 1st and 3.5 times as 2nd, truncate at apex; their surface, covered with several long and short, pale, semi-erect hairs. Antennae long, reaching the basal fifth of elytra; 2nd segment very small, rounded, almost completely hidden by scape, 1st and 3nd cylindrical, not swollen, 1st somewhat wider and longer, 4th–10th rectangular, each one slightly shorter than previous, slightly sinuate at base, narrower than, or same width as previous basal segments, apical segment almost completely conical with sinuate and pointed tip. All segments covered with thin, pale, very short, sparse and semi-erect pubescence.
Pronotum approximatly square, evenly sinuate at base just behind the middle, anterior margin very slightly convex, protruding, posterior straight, all angles rounded, anterior angles almost right, disc strongly depressed at basal fifth; surface smooth, shining, sparsely punctate in middle and densely on sides and near hind angles, microsculpture indistinct; covered with double pubescence: uniform, pale, short and semi-erect setae, and two groups of several, sparse, long, black and erect setae on anterior angles.
Scutellum transverse-rectangular, small, almost completely hidden by pronotum, with straight anterior margin; surface bright, densely punctate and pubescent with thin, pale and depressed setae.
Elytra parallel, narrow, slightly widened posteriorly; shoulders distinct; apices evenly rounded, simple, lacking impressions or appendages; surface dull, densely punctured at base and shagreened elsewhere, evenly covered with fine, short, pale and semi-erect pubescence and with sparse, erect, dark and long setae.
Legs rather short, thin; posterior femora reaching the apical fifth of the elytra; covered with very light, short, depressed, sparse and somewhat longer (compared with elytral pubescence) hairs; claw segments darker than previous ones. Tibiae thin, very slightly expanded anteriorly, rounded. Tarsi narrow; claw segment largest, depressed dorsally,as long as 1st and 2nd together, and somewhat longer general length of 3rd and 4th. Claws narrow, sharp, appearing almost straight, with a small indentation basally.
Apical sternite (Fig. 12) narrow, transverse, 2.3 times wider than long, distinctly divided in two lobes coupled with a transparent membrane, each lobe fitted with a long, strong and dark seta; apical tergite (Fig. 11) almost suboval, 1.4 times longer than wide, evenly rounded, slightly sinuate and lacking emargination on distal side, covered with black setae. Median lobe of the aedeagus (Fig. 13) simple, slightly curved ventrally, with short, stretched, slightly widened and ventrally curved apex, i.e. lamella; groups of 2–3 small denticles sets in median and apical parts of internal sac, together with, a strong, laterally curved tooth in basal half of it can be seen inside the median lobe. Tegmen elongate, narrow, 1.7 times longer than wide, weakly emarginated apically with short, thin and pointed appendages on sides (Fig. 14).
Length (male) 4.2 mm, width (at elytral base) 1.2 mm.
Female. Similar to male but antennae narrower; elytra strongly widened behind the middle; pronotum smooth, almost completely lacking punctures in the middle; claw segment shorter.
Length (female) 4.6 mm, width (at elytral base) 1.3 mm.
