Body length 4.76 mm; LFW 3.20 mm. Color: head, mesosoma and metasoma black; mandible and antenna black; legs black; wings subhyaline, veins light castaneous. Pubescence conspicuous. Head (Fig. 61): mandible with 5 teeth (Fig. 62). Clypeus with trapezoidal median lobe, with a median polished spot. First four antennal segments in a ratio of 40:7:21:20; segment III 2.0 X longer than thick, segment XI 2.75 X; flagellar pubescence subappressed, with some erect setae. Frons strongly coriaceous, with small, conspicuous and abundant punctures, WH 0.95 X LH, WF 0.71 X WH, WF 1.48 X HE; DAO 0.12 X WF; OOL 1.15 X WOT, frontal angle of ocellar triangle acute; VOL about 0.87 X HE. Vertex broadly convex. Temples slightly divergent anteriorly. Mesosoma: pronotum and mesonotum coriaceous, punctured as on frons, pronotal disc short, concave in profile, with a posterior transverse furrow; notauli shallow, present only apically; parapsidal furrows almost complete; scutellar disc coriaceous. Propodeal disc 1.02 X as long as wide, 1.86 X as long as high, basal triangle striate, posterior portion of disc and declivity finely strigulate, median carina incomplete, the posterior absent, lateral portion of propodeum weakly aciculate. Mesopleuron strongly punctured, with a large and polished callus. Fore wing with discoidal vein spectral, weakly pigmented, interstitial with median vein. Genitalia (Fig. 63-64): paramere with ventral arm approximately 2.5 X wider than dorsal arm, the ventral concave; vannus with 5 grooves; aedeagus elliptical, apex emarginate, wide before the apex.

Discussion.-This species is similar to P. cuspidatum , but here the apical margin of clypeus is concave and the ventral arm of paramere is narrower. Etymology.-The specific epithet refers to the genitalia size. Distribution.-Brazil ( Espirito Santo).
