Description. Male holotype. Length 2.0 mm, width 1.6 mm; body oval, elytron with side rounded, wider than pronotal base, widest at middle of elytra. Dorsal surface entirely shiny without trace of microsculpture. Color black ( Fig. 485 ); head with vertex brown, frons reddish yellow with narrow, pale yellow median vitta in basal ½, not seen in image ( Fig. 487 ); pronotum with lateral 1/4 reddish yellow; elytron bluish black; scutellum black; antenna, mouthparts, legs yellow; epipleuron dark reddish brown; abdomen with ventrite 3 dark brown, ventrites 4, 5 laterally brownish yellow, medially dark brown, ventrite 5 brownish yellow brown. Head punctures small, separated by a diameter or less; pronotal punctures slightly larger than on head, separated by a diameter or less; elytral punctures larger than on pronotum, separated by less than twice a diameter; prosternal punctures large, sparse, separated by 1 to 3 times a diameter; mesosternal punctures as large as on prosternum, separated by a less than 3 times a diameter; metasternal punctures smaller than on mesosternum, separated by less than 3 times a diameter; abdomen with punctures on ventrites 1–3 smaller than on metasternum, separated by 1 to 2 times a diameter, punctures on remaining ventrites smaller, separated by about a diameter. Head with frons not widened from vertex to clypeus, sides parallel, slightly wider than eye measured at vertex; eye canthus short; apical maxillary palpomere short, weakly widened from base to apex. 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, with feeble depressions for reception of femoral apices. Prosternum longer than wide, mesosternum with base weakly arcuate, lateral carina slender, extended midway between apex of coxa and prosternal base. Postcoxal line on ventrite 1 long, angulate, extended 4/5 distance to ventrite apex ( Fig. 486 ). Apex of ventrite 5 strongly arcuate. Genitalia with basal lobe slightly longer than paramere, wide, widest medially, lateral margin curved from base to acute apex, apex not emarginate; paramere weakly curved, slender, nearly equal in width to rounded apex, without marginal serrations ( Fig. 488, 489 ); sipho robust, apex sinuate with slender apical projection ( Fig. 490 ).

Female. Unknown.

Variation. Length 1.8 to 2.0 mm. Width of pronotal pale area slightly variable in width, ventral surface color varies from black to dark brown or reddish brown.

Type material. Holotype male; PANAMA: CANAL ZONE, 100m, 5.0 mi. NW Gamboa, 09 o 10' 00" N 079 o 45'00" W, 23–24Oct1975, Canopy fogging experiment in Luehea seemannii, Pyrethrin fog, sample 5b, 24 X 1975. ( USNM) . Paratypes; 4, same data as holotype. ( USNM) .

Remarks. Prodilis sabrina is distinguished by the widely pale lateral pronotal margin; bluish black elytron; and male facial pattern.
