Description. Length (pronotum + elytra) = 1.80–2.08 mm; greatest width = 1.16–1.44 mm. Reddish brown, shiny. Head punctures fine medially, moderately coarse on vertex, irregularly spaced. Antennal grooves not well defined. Mandibles short, forming semicircle when closed; two teeth at apical one-third of left mandible. Antennal club slender; antennomere 8 disc-like, distinctly narrower than apex of 7; apical antennomere slightly narrower than 9 and 10. Eyes of normal size. Pronotum broad, sides rounded, posterior angles roundly obtuse, basal margin rounded. Pronotal punctures minute and sparse. Elytral strial punctures round and deep, smaller near base, variably separated; interstrial punctures minute and sparse. Metasternum with fine punctures medially; coarse, unevenly spaced punctures laterally. Male mesofemur unmodified. Male mesotibia weakly concave on inner margin. Abdominal sternites III–VII each with basal transverse row of large punctures. Median lobe of aedeagus ( Fig. 9 View Figures 7–15 ) cylindrical, strongly curved dorsoventrally; apical one-third progressively flattened to apex; paired apices broad and flat. Parameres narrow, each bearing two apical setae, not reaching apex of median lobe. Internal sac as in Fig. 9 View Figures 7–15 .
