12. Pentilia muriel Gordon and González , new species

Description. Male holotype. Length 2.3 mm, width 2.0 mm; dorsal surface shiny. Color yellow; head yellow with black clypeus; pronotum with lateral 1/3 yellow; elytron with black border, sutural border narrower than lateral border, with basal projection inside humeral callus ( Fig. 62 ); venter black except mouthparts, legs yellow; epipleuron yellowish brown; abdomen yellow with median 1/3 of ventrites 1-3 dark brown. Head punctures small, separated by less than a diameter; pronotal punctures as large as on head, separated by less than to 3 times 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 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, slightly wider than eye, clypeal apex widely emarginate, lateral angle abruptly curved ( Fig. 63 ); eye canthus about 1/2 width of eye. Prosternum with lateral carina on each side short, straight, extended from apex of intercoxal process less 1/4 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, sides parallel in basal 3/4, then rounded to narrow apical 1/8, apex rounded; paramere slender, weakly curved, apex rounded ( Fig. 64, 65 ); penis long, slender, apex shortly attenuate; basal capsule slender, inner arm slender, slightly curved, apex rounded, outer arm short, apex abruptly rounded ( Fig. 66 ).

Type material. Holotype male; Colombia, Antioquia, Medellin , 1600 m, 13-X-2012, leg. J. C. Gómez, En cítricos ( Citrus sinensis ) ( CTNI)

Remarks. Pentilia muriel is somewhat similar to other species with the same type of dorsal color pattern, but is distinguished by a projection of basal border on the elytron with a projection inside of the humeral callus. The male genitalia also are distinct from those of similar appearing species.
