Figures 1 View FIGURES 1 – 3 –4, 6, 8

Description: Male. ( Fig. 1 View FIGURES 1 – 3 ). Length: 10.3–11.4 mm (holotype 10.3 mm); width: 2.5–2.8 mm (holotype 2.5 mm). Body flattened, slender (Fig. 4). General colour of body brown, faintly shining; head and pronotum slightly darker, anterior margin and hind angles of pronotum slightly lighter. Body covered with fine and regular, moderately dense yellow pubescence.

Head. Moderately convex; with long pale yellow pubescence; punctures coarse and slightly larger and denser than on pronotum. Antennae exceeding by 1.5 articles the apices of prosterior angles of pronotum; second and third segment subcylindrical and of equal length, taken together 1.3x longer than fourth; fourth-tenth segments slightly subtriangular, on average 2.2x longer than wide.

Thorax. Pronotum minimally wider than long (length: 2.2–2.3 mm; width: 2.3–2.5 mm), widest at prosterior angles; disc flattened, along midline with a distinct smooth line; sides of pronotum subparallel from base to anterior third, posterior angles sharp, weakly divergent with carina subparallel to lateral margins; punctures dense, intervals between punctures equal to diameter of puncture or slightly smaller; punctuation on disc sparser, intervals between punctures noticeably larger than diameter of punctures. Propleuron as well as pronotum punctate; punctation of prosternum sparse, interstices longer than their diameter.

Elytra 3.4–3.5x longer than pronotum; disc distinctly flattened, sides parallel from base to middle, then gradually tapering to apex; elytral striae with fine punctures, intervals flat, with fine and sparse punctures, with large and deep punctures apically; slightly shining.

Abdomen. Puncture less dense than on metasternum, interstices longer than their diameter.

Legs. Third tarsal joint with long and broad lamella beneath; fourth tarsal joint small, extending past inferior lobe of third; lamella extends up to half of the fifth joint. Claws pectinate.

Male genitalia. Aedeagus as in Fig. 6 View FIGURES 6 – 9 (length: 1.4–1.5 mm). Median lobe slender (0.82x) and longer (1.1x) than parameres; apex of parameres arcuate.

Female. ( Fig. 3 View FIGURES 1 – 3 ). Length: 10.2 mm; width: 2.5 mm. Body light brown. Pronotum slightly wider than long (length: 2.2 mm; width: 2.3 mm). Elytra 3.3x longer than pronotum. Antennae exceeding by 1 articles the apices of prosterior angles of pronotum. Similar to male in all other features.

Female genitalia. Bursa copulatrix as in Fig. 8 View FIGURES 6 – 9 a, b. Sclerotized plates asymmetric: first plate (a) elongated with subparallel sides, narrowed at anterior third (length: 1.7 mm; width: 0.4 mm) and second plate (b) drop-shaped (length: 1.4 mm; width: 0.6 mm); plates covered with small teeth.
