Description. Male holotype. Length 1.8 mm, width 1.6 mm; dorsal surface entirely shiny. Color black; head yellowish brown; pronotum with lateral 1/4 yellow ( Fig. 72 ); venter yellow except lateral 1/3 of mesosternum, metasternum black. Head with punctures large, separated by a diameter or less; pronotal punctures small separated by a diameter or less; elytral punctures larger than on pronotum, separated by one to three times a diameter; prosternal punctures fine, separated by less than a diam- eter; mesosternal punctures larger than on prosternum, separated by about a diameter, metasternal punctures as large as on mesosternum, separated by a diameter or less medially, absent on lateral 1/4; abdominal ventrites 1, 2 with fine punctures separated by up to three times a diameter medially, ventrites 2–4 finely, densely punctured medially; ventrite 5 finely, densely punctured. Head with frons narrow, parallel sided, about as wide as eye, clypeal apex weakly arcuate ( Fig. 73 ); eye canthus short, about half width of eye. Prosternum with lateral carina on each side curved, extended from apex of intercoxal process to lateral margin of prosternum. Epipleuron not descending externally. Postcoxal line on basal abdominal ventrite curved, extended nearly to rear margin of ventrite. Genitalia with penis guide 3/4 as long as paramere, narrow, widest at base, gradually tapered in apical 1/4 to narrow, slightly emarginate apex; paramere slightly curved, mostly parallel sided, apex rounded ( Fig. 74, 75 ); penis robust, apex lost, basal capsule robust, dark brown, inner arm short, apically hooked, outer arm short, narrowed from base to acute apex ( Fig. 76 ).
