Description. Male holotype. Length 2.6 mm, width 2.5 mm. Dorsal surface shiny, pronotum with distinct microsculpture, elytron with faint trace of microsculpture. Color dark brown; head yellow; pronotum with lateral 1/3 yellow; elytron with lateral 1/5 brownish yellow from base to apex ( Fig. 32 ); venter yellow. Head without punctures; pronotal punctures small, separated by a diameter or less; elytral punctures larger than on pronotum, separated by less than a diameter to three times a diameter; prosternal punctures large, separated by less than a diameter; mesosternal punctures larger than on prosternum, separated by less than a diameter, metasternal punctures large, separated by two or three times a diameter medially, entirely absent in lateral 1/3; basal abdominal ventrite with coarse punctures separated by about a diameter medially, lateral 1/3 of ventrite and ventrites 2–4 lacking punctation, ventrite 5 with dense, fine punctation. Head with frons parallel-sided, medially depressed, twice as wide as eye, apex truncate medially, lateral 1/8 slightly retracted, angle acute ( Fig. 33 ); eye canthus long, about 1/2 width of eye. Prosternum with lateral carina on each side extended from apex of intercoxal process to midpoint of prosternum. Epipleuron strongly descending externally. Postcoxal line on basal abdominal ventrite evenly curved, extended 3/4 distance to rear margin of ventrite. Genitalia long, penis guide nearly as long as paramere, parallel-sided with apical 1/8 narrowed to rounded apex; paramere slender, parallel-sided, apex rounded ( Fig. 35, 36 ); penis long, slender, apical 1/3 attenuate; base with inner arm slender, curved, narrowed from base to apex, outer arm short, wide ( Fig. 37 ).

Female. Similar to male except head weakly depressed medially; lateral 1/3 of pronotum yellow, median 2/3 dark brown; genitalia with spermathecal capsule short, wide, slightly tapered from ramus to rounded apex of cornu ( Fig. 38 ).

Variation. Length 2.6 to 3.0 mm, width 2.5 to 2.7 mm. Brownish yellow macula on elytron often narrowly extended along suture to apex.

Type material. Holotype male: Brit. Guiana ( Guyana), Blairmont , Sept. 1923 H. E. Box Collector, Attacking Coccin on Anon sp,. Pres. by Imp. Inst. Ent. Brit. Mus. 1930-336. ( BMNH) . Paratypes: 4, same data as holotype except lacking host. ( BMNH).
