3. Pentilia traci Gordon and González , new species

Description. Male holotype. Length 2.5 mm, width 2.4 mm; dorsal surface shiny except head densely alutaceous. Color black; head yellow; pronotum with lateral 1/4 yellow; elytron with wide, yellow lateral margin ( Fig. 13 ); venter yellow except meso-, metasternum brown; abdomen yellow except basal abdominal ventrite with median 1/3 apically brown. Head punctures not visible, hidden in alutaceous sculpture, frons ( Fig. 14 ); pronotal punctures small, separated by less than to 3 times a diameter; elytral punctures larger than on pronotum, separated by less than to twice a diameter, becoming larger, denser toward lateral margin; prosternum with punctures separated by less than a diameter; mesosternum with coarse punctures separated by a diameter or less; metasternum with large punctures separated by less than to twice a diameter in median 3/4, punctures becoming sparse or absent in lateral 1/4; abdominal ventrites 1, 2 with coarse punctures separated by less than to twice a diameter; ventrites 3–4 finely, densely punctured medially; ventrite 5 finely, densely punctured. Head with frons parallel sided, 1.5 times as wide as eye, clypeal apex widely emarginate, lateral angle abruptly curved (Fig.); eye canthus long, about 3/4 width of eye. Prosternum with lateral carina on each side long, straight, extended from apex of intercoxal process to apex of prosternum. Epipleuron strongly descending externally. Postcoxal line on basal abdominal ventrite curved, extended 7/8 distance to rear margin of ventrite. Genitalia with basal lobe as long as paramere, sides gradually narrowed from base to abruptly rounded apex; paramere slender, nearly straight, apex rounded ( Fig. 15, 16 ); penis short, robust, apex shortly attenuate, margins separated anterior to apex, lower margin straight; basal capsule slender, inner arm long, slightly curved, apically rounded, outer arm shorter than inner arm, apex rounded ( Fig. 17 ).

Female. Similar to male except head yellowish brown; genitalia with spermathecal capsule not examined.

Variation. Length 2.3 to 2.6 mm, width 2.2 to 2.5 mm.

Type material. Holotype male; Brasilien, Nova Teutonia , 27° 11’ B. 52° 23’, Fritz Plaumann, Jan. 1939, Brit. Mus. 1946-191. ( BMNH) . Paratype 1, same data as for holotype. ( BMNH )
