description: 10. Pentilia mable Gordon and González, new species
Description. Male holotype. Length 2.2 mm, width 2.0 mm; dorsal surface shiny with faint trace of microsculpture. Color yellow; head reddish brown; pronotum with lateral 1/4 yellow; elytron with dark brown border, sutural border slightly narrower than lateral border, lateral border slightly widened at apical declivity (Fig. 50); venter yellowish brown except mouthparts, legs, epipleuron, abdomen yellow. Head punctures small, separated by a diameter or less; pronotal punctures smaller than on head, separated by a less than to 3 times a diameter; elytral punctures as large as on pronotum, separated by less than to twice a diameter, becoming larger, denser toward lateral margin; prosternum with small punctures separated by less than a diameter; mesosternum with punctures as large as on prosternum, separated by a diameter or less; metasternum with punctures slightly larger than on prosternum, separated by less than to twice a diameter in median 2/3, punctures becoming sparse or absent in lateral 1/3; abdominal ventrites 1, 2 with coarse punctures separated by less than to 3 or 4 times a diameter; 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. 51); eye canthus long, about 3/4 width of eye. Prosternum with lateral carina on each side short, straight, extended from apex of intercoxal process to less than 1/2 distance 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, narrow, sides narrowed from base to abruptly rounded apex; paramere slender, weakly curved, apex rounded (Fig. 52, 53); penis long, slender, apex with attenuate apex nearly as long as rest of penis; basal capsule slender, inner arm absent, deep excavation in place of it, outer arm long, apex rounded (Fig. 54).
Female. Similar to male except head black, pronotum entirely dark brown; genitalia with spermathecal capsule slender, slightly curved, ramus not enlarged, apex of cornu widely rounded (Fig. 55).
Variation. Length 2.0 to 2.2 mm, width 1.8 to 2.0 mm, dark elytral border varies slightly in width.
Type material. Holotype male; Fusagasugá, Colombia, Cnd (Cundinamarca), I.II.40, Murillo No 76. (USNM). Paratypes 42. 23, same data as holotype except some dates 18.II.40, 6.XI,40; 18, Colombia, Cald, Neira, 5.II.41, alt. 2025, Murillo No 5478. (USNM).
Remarks. Pentilia mable somewhat resembles P. chelsea but is smaller and has a mostly pale elytron bordered with dark brown. Male genitalia are also dissimilar, with the basal lobe in P. mable very narrow, and the penis with an extended attenuation of the apex; the basal lobe in P. chelsea is wide and apex is not extremely attenuate.
