1. Pentilia sadie Gordon and González , new species

Description. Male holotype. Length 2.6 mm, width 2.4 mm; dorsal surface with head densely alutaceous; pronotum distinctly alutaceous; elytron faintly alutaceous. Color brownish yellow ( Fig. 1 ); head yellow; pronotum with lateral 1/4 yellow; abdomen yellow. Head punctures not visible, hidden in alutaceous sculpture; pronotal punctures small, separated by a diameter or less; elytral punctures slightly larger than on pronotum, separated by less than to 3 times a diameter; prosternum, mesosternum strongly alutaceous, no punctures visible; metasternum shiny, apparently lacking punctures; abdominal ventrites 1, 2 with fine punctures separated by less than to 3 times a diameter; ventrites 2–4 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. 2 ); 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 as long as paramere, sides almost parallel in basal 4/5, slightly indented medially, apical 1/5 narrowed to broadly rounded apex; paramere slender, nearly straight, apex rounded ( Fig. 3, 4 ); penis long, slender, apex attenuate, margins separated anterior to apex, lower margin curved ( Fig. 5 ).

Female. Similar to male except head brown, pronotum faintly paler in lateral 1/4; ramus of spermathecal capsule wide, cornu weakly curved, apex acute ( Fig. 6 ).

Variation. Length 2.3 to 2.6 mm, width 2.3 to 2.4 mm.
