21. Pentilia paulette Gordon and González , new species

Description. Male holotype. Length 2.2 mm, width 1.9 mm; dorsal surface weakly alutaceous. Color black; head yellow with black clypeal apex; pronotum with lateral 1/3, anterior 1/4 yellow ( Fig. 110 ); venter black except mouthparts, pro- and mesolegs yellow; metafemur brown; epipleuron reddish brown; abdomen yellow except median 1/3 of ventrites 1–4 brown. Head punctures small, separated by less than a diameter; pronotal punctures as large as on head, separated by a less than to twice a diameter; elytral punctures larger than on pronotum, separated by less than to 3 times a diameter; prosternum with small punctures separated by less than a diameter; mesosternum nearly impunctate; metasternum with punctures in median 2/3 larger than on prosternum, separated by less than to twice a diameter, absent in lateral 1/3; abdominal ventrites 1, 2 nearly impunctate with small scattered punctures; ventrites 3–4 finely, densely punctured medially; ventrite 5 finely, densely punctured. Head with frons parallel sided, 1.2 times as wide as eye, clypeal apex widely emarginate, lateral angle abruptly curved ( Fig. 111 ); eye canthus long, about 3/4 width of eye. Prosternum with lateral carina straight, extended from apex about 1/2 distance to base of prosternum. Epipleuron strongly descending externally. Postcoxal line on basal abdominal ventrite curved, extended 7/8 distance to rear margin of ventrite. Genitalia with penis guide long, basal lobe as long as paramere, gradually narrowed in basal 2/3, slightly more strongly tapered in apical 1/3 to rounded apex; paramere slender, nearly straight, apex rounded ( Fig. 112, 113 ); penis slender, apical 1/5 attenuate; basal capsule with inner arm short, straight, apex curved, outer arm widened from base to broadly rounded apex ( Fig. 114 ).

Female. Similar to male except head brown, lateral 1/4 of pronotum brown; spermathecal capsule long, slender, ramus not enlarged, cornu bent before apex, apex rounded ( Fig. 115 ).

Variation. Length 2.2 to 2.5 mm, width 1.9 to 2.1 mm.

Type material. Holotype male; PERU 1947, Tingo Maria , Weyrauch. ( USNM) . Paratypes 28, 7, same data as for holotype ; 9, Tingo Maria , Peru 1949, J. DieguezC ; 4, Tingo Maria, ( Rio Huallaga ), 700 m, X.1946, leg. Weyrauch ; 2, Tingo Maria, Peru , 16.I.49, D. Isely collector ; 6, Peru, Madre de Dios, Tahuamanu, Inapari , 295 manm. 22-IV-2010.

Remarks. Male genitalia must be examined to identify this species, but the Peruvian type locality will aid in recognition.
