Description of the holotype (♂)
Body moderately elongate, weakly convex (Fig. 1D); LB = 2.31 mm; maximum pronotal width at base (WP = 0.81 mm); maximum elytral width at basal third (WE = 1.08 mm). Dorsum yellowish, not metallic, with scutellum, elytral suture and elytral punctuation slightly darkened. Frons and vertex microreticulate, with small, shallow punctures; head grooves distinctly impressed, not continued to postantennal region (Fig. 4C); genae and frontal carina short; antennae about as long as ½ body length (LAN = 1.28 mm; LAN/LB = 0.55), basally yellow, gradually and slightly darker towards apex; LA: 100:64:54:64:82:89:91:100:100:100:118. Pronotum trapezoidal, transverse (LP = 0.48 mm; WP/LP = 1.71), laterally straight (Fig. 4C); anterior angles distinctly prominent; antebasal transverse sulcus moderately impressed, slightly sinuate, with small lateral fovea; pronotal surface microreticulate, with clear, unevenly distributed punctuation. Elytra moderately elongate (LE = 1.68 mm; WE/LE = 0.64), laterally slightly arcuate; punctuation slightly larger than on pronotum and clearly impressed; interstriae very finely microreticulate and sparsely micropunctuate.
Legs yellow; first pro- and mesotarsomeres distinctly dilated; adhesive setae present on ventral side of first pro-, meso- and, partially, metatarsomeres. Venter light brown; last abdominal ventrite laterally clearly incised, without special preapical impressions. Median lobe of aedeagus (LAED = 0.89 mm; LE/ LAED = 1.88) (Fig. 8E) in ventral view tapered from basal third toward apex; basal part narrower; apex subtriangular, slightly rounded, with a median rounded small tooth; ventral surface with median sulcus basally wide and two prelateral carinae; in lateral view, median lobe thin, strongly bisinuate; dorsal ligula from half length to apical part of median lobe of aedeagus, wide, tapered toward apex.
