description: 18. Pentilia kari Gordon and González, new species
Description. Male holotype. Length 2.0 mm, width 1.8 mm; dorsal surface shiny. Color black; head yellow with brown clypeal apex; pronotum with lateral 1/3, anterior 1/3 yellow (Fig. 94); venter yellow; abdomen yellow except median 1/3 of ventrites 1, 2, light brown. Head punctures small, separated by less than a diameter; pronotal punctures as large as on head, separated by less than a diameter; elytral punctures larger than on pronotum, separated by less than to 3 times a diameter, becoming larger, denser toward lateral margin; prosternum with small punctures separated by less than a diameter; mesosternum with punctures larger than on prosternum, separated by about a diameter; metasternum with punctures in median 1/3 as large as on mesosternum, separated by less than to twice a diameter in median 1/3, punctures absent in lateral 1/3; abdomen with ventrites 1, 2 coarsely punctured, punctures separated by about a diameter; ventrites 3, 4 densely punctured; 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. 95); eye canthus long, about 3/4 width of eye. Prosternum with lateral carina on each side straight, extended from apex of intercoxal process to about 1/4 distance to apex of prosternum. Epipleuron strongly descending externally. Postcoxal line on basal abdominal ventrite curved, extended 3/4 distance to rear margin of ventrite. Genitalia with penis guide long, basal lobe as long as paramere, sides nearly parallel in basal 2/3, gradually narrowed from base to rounded apex in apical 2/3; paramere weakly sinuate, apex rounded (Fig. 96, 97); penis long, slender, apex briefly attenuate; basal capsule with inner arm short, narrow, apically acute, outer arm wide, long, apex rounded (Fig. 98).
Female. Similar to male except head, pronotum black; spermathecal capsule with widened ramus, cornu slender, medially bent, apex rounded (Fig. 99).
Variation. Length 1.8 to 2.2 mm, width 1.7 to 2.0 mm. Female head, pronotum may be dark brown instead of black, extent of yellow area on male pronotum variable, male venter may have meso-, metasternum dark brown.
Type material. Holotype male; COLOMBIA: Sasaima, Cund. (Cundinamarc), 19 Mar 1965, J. A. Ramos collector. (USNM).

Other specimen. 1, Carinas, Rio Beni, Boliv. Jan, MR Lopez Collector, Mulford BioExpl, 1921-22. (USNM).
Remarks. This Colombian species is recognized primarily by the male genitalia, but a pronotum with wide lateral and anterior yellow areas also is of value in identification, especially in distinguishing it from P. egena.
