This species may be distinguished by the following combination of characters: body elongate with elytra and abdomen broad, moderately robust, dark brown to black with tarsi and tibiae often reddish-brown, elytra sometimes with reddish tinge (Figs 35); length 3.5-4.0 mm; integument of forebody with moderately pronounced meshed microsculpture, surface highly glossy; head about one-eighth narrower than maximum width of pronotum (Fig. 35); pronotum transverse, about evenly wide in posterior half, then distinctly narrowing apicad, forming round apical angles (Fig. 35); elytra at suture slightly longer than pronotum (Fig. 35); basal four articles of metatarsus about the same length, each shorter than fifth article. Male. Tergite VIII with apical margin broadly arcuate, without teeth or crenulations (Fig. 38); sternite VIII rounded apically (Fig. 39); median lobe of aedeagus with tubus broadly arcuate ventrally and with apex narrow and pointed in lateral view (Fig. 36); tubus broad and triangular apically in dorsal view (Fig. 37). Female. Tergite VIII broadly arcuate apically (Fig. 40); sternite VIII evenly rounded apically, with antecostal suture distinctly sinuate (Fig. 41); spermatheca with spherical capsule with invagination deep and narrow, stem S-shaped, gradually becoming very narrow posteriad (Figs 42, 43).
