Description. Male holotype. Length 1.7 mm, width 1.3 mm; body oval, elytron with side weakly rounded, wider than pronotal base, widest at middle of elytra. Dorsal surface entirely shiny without trace of microsculpture. Color reddish brown; head with basal 1/4 of frons and vertex reddish brown, remainder of head yellow ( Fig. 504 ); pronotum dark reddish brown medially, lateral 1/3 paler yellowish brown; elytron with elongate oval yellow macula extended diagonally from posterior to humeral callus to beyond midpoint of elytron, additional round, yellow macula present medially on apical declivity ( Fig. 502 ); antenna, mouthparts yellow; legs pale reddish brown; ventral surface including epipleuron dark reddish brown; abdomen yellowish brown. Head punctures small, separated by a diameter or less; pronotal punctures slightly smaller than on head, separated by less than twice a diameter; elytral punctures larger than on pronotum, separated by less than twice a diameter; prosternal punctures large, sparse, separated by less than twice a diameter; mesosternal punctures nearly absent; metasternal punctures large, coarse, separated by less than a diameter on anterior and lateral borders, punctures on remainder of metasternum small sparse; abdomen with punctures on ventrites 1–3 large, separated by less than twice a diameter, punctures on remaining ventrites smaller, separated by about a diameter. Head with frons not widened from vertex to clypeus, sides of frons parallel, 1.4 times 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, basal ½ as wide as pronotal hypomeron, with feeble depressions for reception of femoral apices. Prosternum longer than wide, longer than mesosternum, expanded basally, base strongly arcuate, lateral carina slender, extended anterior to apex of coxa. Postcoxal line on ventrite 1 long, slightly angulate, extended to ventrite apex. Apex of ventrite 5 arcuate ( Fig. 503 ). Genitalia with basal lobe longer than paramere, wide, widest medially, lateral margin curved from base to blunt apex, apex not emarginate; paramere weakly curved, slender, equal in width to rounded apex, without marginal serrations ( Fig. 505, 506 ); sipho long, slender, slightly bent at apical 1/6 ( Fig. 507 ).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; Paramaribo, DG ( Dutch Guiana, Suriname) Jan.’54, van Dinther. ( USNM).

Remarks. A combination of elytral color pattern and strongly produced anterior prosternal margin characterize P. harriet .
