11. Pentilia ernestine Gordon and González , new species

Description. Male holotype. Length 2.8 mm, width 2.6 mm; dorsal surface shiny with faint trace of microsculpture. Color reddish yellow; head yellow; pronotum with lateral 1/3 yellow, median 1/3 dark brown with faint reddish median vitta; elytron reddish yellow with dark brown vitta in lateral 1/4, sutural margin narrowly dark brown ( Fig. 56 ); venter yellow. 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 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, 1.5 times as wide as eye, clypeal apex widely emarginate, lateral angle abruptly curved ( Fig. 57 ); eye canthus long, about 3/4 width of eye. Prosternum with lateral carina on each side straight, extended from apex of intercoxal process less than 1/2 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 basal lobe slightly longer than paramere, sides weakly widened from base to broadly rounded apex, apex slightly indented medially; paramere slender, weakly curved, apex rounded ( Fig. 58, 59 ); penis long, slender, shortly attenuate apically; basal capsule slender, inner arm short, weakly curved, apex rounded, outer arm short, apex rounded ( Fig. 60 ).

Female. Similar to male except spermathecal capsule as in Fig. 61 .

Variation. None observed.

Type material. Holotype male; COLOMBIA, Caldas, Neira, Trocaderos , 3-XII-2009, leg. J. Monsalve, Coccideos. ( CTNI) . Paratypes 2, same data as for holotype ( CTNI).

Remarks. Pentilia ernestine has male genitalia very similar to those of P. chelsea , but both are maintained as valid based on differences in the dorsal color pattern.
