Description. Male holotype. Length 2.0 mm, width 1.6 mm; body oval, elytron with side slightly rounded, wider than pronotal base, widest at middle of elytra. Dorsal surface entirely shiny. Color blue (Fig. 288); head black; pronotum with reflexed lateral margin blue; elytra with reflexed lateal margin reddish brown; antenna, epipleuron, legs yellow; mouthparts yellow except maxilla dark brown; venter dark reddish brown; abdomen brown. Head punctures large, separated by a diameter or less; pronotal punctures as large as on head, separated by less than 4 times a diameter; elytral punctures larger than on pronotum, separated by less than 3 twice a diameter; prosternal, mesosternal punctures large, separated by a diameter or less; metasternum with large punctures along anterior and lateral borders, punctures on remaining surface absent or small, sparse; punctures on abdominal ventrites 1–3 large, separated by less than twice a diameter, punctures on remaining ventrites small, separated by about a diameter. Head densely pubescent, frons widened from vertex to clypeus, narrower than eye measured at vertex (Fig. 290); eye canthus short; apical maxillary palpomere long, slender, narrowed to apex in apical 1/3. Pronotum widest at middle, reflexed lateral margin wide, equal in width from base to apex. Epipleuron flat, wide in basal ½, as wide as pronotal hypomeron. Prosternum slightly wider than long, slightly longer than mesosternum, apical margin weakly emarginate medially, large, setose anterolateral projection present. Postcoxal line on ventrite 1 long, slightly angulate, extended 4/5 distance to apical margin of ventrite (Fig. 289). Apex of ventrite 5 slightly arcuate. Genitalia with phallobase short, basal lobe as long as paramere, slender, parallel sided in basal 4/5, apical 1/4 narrowed to slender, deep apical emargination; paramere straight, basal 2/3 wide, apical 1/3 tapered to rounded apex, dorsal margin of apical 1/3 deeply emarginate before apex, dorsal margin not serrate (Fig. 291, 292); sipho short, robust (Fig. 293).

Type material. Holotype male; COSTA RICA: Turrialba, 22 June 1951, OLCartwright. (USNM).
