Description. Male holotype. Length 2.0 mm, width 1.7 mm; dorsal surface shiny, head distinctly alutaceous, elytron with faint trace of microsculpture. Color brownish yellow; head yellow; pronotum with small, triangular, faint brown macula at middle, small, dark brown macula present on lateral 1/3; elytron with two large, black maculae, anterior macula irregularly rectangular, angled from pronotal margin toward lateral margin of elytron, posterior macula on apical declivity, suture narrowly black, black area widened at middle of elytron then continued narrowly along pronotal base to anterior macula ( Fig. 21 ); pro-, meso-, metasternun black; abdominal ventrites 2, 3 medially dark brown. Head with dense punctures separated by a diameter or less; pronotal punctures small, separated by less than to twice a diameter; elytral punctures larger than on pronotum, separated by up to three times a diameter; prosternal punctures small, indistinct, separated by about a diameter; mesosternal punctures larger than on prosternum, separated by less than a diameter; metasternal punctures large, separated by a diameter or less medially, absent in lateral 1/3; 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 parallel sided, feebly depressed medially, 1.2 times as wide as eye, clypeal apex weakly curved ( Fig. 22 ); 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 weakly descending externally. Postcoxal line on basal abdominal ventrite curved except median portion flattened, extended nearly to rear margin of ventrite. Genitalia long, penis guide 3/4 as long as paramere, tapered from base toward apex, noticeably narrowed at apical 1/8 then parallel sided to rounded apex, paramere slender, slightly widened in apical 1/4, apex ( Fig. 23, 24 ); penis long, robust, apex attenuate; basal capsule large, inner arm elongate, slender, apex rounded, outer arm wide, apex narrowly rounded; rounded ( Fig. 25 ).
