( Fig. 23, 24 , 34 )

Diagnostic description. Length (pronotum + elytra) = 2.92–2.96 mm; greatest width = 1.92 mm. Head punctures variable in size and spacing. Antennal club slender; antennomere 7 narrower than 9 and 10; antennomere 8 narrow, disk-like; apical antennomere narrower than 9 and 10. Sides of pronotum rounded, posterior angles broadly obtuse. Pronotal punctures fine, moderately widely spaced. Elytral strial punctures large, round, deep and closely spaced; interstrial punctures minute, distantly spaced; elytral epipleura with pale setae. Metasternal anterior margin with a row of round, deep punctures; punctures not larger in diameter than the shallow lateral punctures of the metasternum. Protarsi and mesotarsi of male bearing white setae ventrally. Male mesotibia curved; mesotibial process broad at base, tapering to apex, nearly as long as large tibial spine. Metafemur slender, male with rounded or triangular expansion near the apex of the lower margin. Abdominal sternite III with a row of indistinct small, deep punctures at anterior margin; sternites IV–VII each with a row of punctures near anterior margin, not visible in dry specimens. Median lobe of aedeagus ( Fig. 23, 24 ) elongate, broad, evenly curved dorsoventrally; paired apical lobes slightly inflexed. Parameres slender, not expanded apically, reaching nearly to apex of median lobe. Inverted internal sac with elongate, darkly sclerotized structure ( Figs. 23, 24 ). Female unknown.
