2. Pentilia bernadette Gordon and González , new species

Description. Male holotype. Length 2.1 mm, width 2.0 mm; dorsal surface with faint microsculpture. Color brownish black; head yellow; pronotum with lateral 1/3 yellow; elytron with narrow yellow lateral margin ( Fig. 7 ); venter yellow; abdomen yellow. Head punctures coarse, separated by a diameter or less; pronotal punctures small, separated by a diameter or less; elytral punctures larger than on pronotum, separated by less than to twice a diameter; prosternum with small punctures separated by less than a diameter; mesosternum with coarse punctures separated by less than to twice a diameter; metasternum impunctate or nearly so; abdominal ventrites 1, 2 with distinct 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. 8 ); eye canthus long, about 3/4 width of eye. Prosternum with lateral carina on each side short, straight, extended from apex of intercoxal process about 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 longer than paramere, sides parallel in basal 4/5, apical 1/5 narrowed to broadly rounded apex; paramere slender, nearly straight, apex rounded ( Fig. 9, 10 ); penis short, robust, basal capsule slender, inner arm long, apically widened, outer arm short, apex truncate ( Fig. 11 ).

Female. Similar to male except genitalia with ramus of spermathecal capsule wide, cornu weakly curved, apex acute ( Fig. 12 ).

Variation. Length 2.0 to 2.6 mm, width 1.9 to 2.4 mm.

Remarks. The black elytra with a narrow, lateral, yellow border distinguish this species from all other species of Pentilia except P. traci . The latter species is Brazilian with a wider lateral border on each elytron and has different male genitalia; see description under P. traci .
