description: 8. Pentilia rachael Gordon and González, new species
Description. Male holotype. Length 2.3 mm, width 2.1 mm; dorsal surface with faint microsculpture except head alutaceous. Color yellow; head yellow except clypeus dark brown; pronotum with lateral 3/8, apical 1/4 yellow, middle of median brown macula with narrow, reddish yellow vitta; elytron black with 4 large, yellow maculae, scutellar macula oval, anterolateral macula oval, macula on apical declivity oval, macula at apex irregularly oval (Fig. 40). Head punctures small, separated by less than a diameter; pronotal punctures small, separated by less than to twice a diameter; elytral punctures larger than 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 less than a diameter; metasternum with punctures larger than on mesosternum, separated by less than to twice a diameter in median 1/2, punctures becoming sparse or absent in lateral 1/3; abdominal ventrites 1, 2 with coarse punctures separated by less than to twice a diameter; ventrites 3–4 finely, densely punctured medially; ventrite 5 finely, densely punctured. Head with frons narrow, parallel sided, 1.2 times as wide as eye, clypeal apex widely emarginate, lateral angle abruptly curved (Fig. 41); eye canthus short, less than 3/4 width of eye. Prosternum with lateral carina on each side short, straight, extended from apex of intercoxal process 1/4 distance to apex of prosternum. Epipleuron strongly descending externally. Postcoxal line on basal abdominal ventrite curved, extended nearly to rear margin of ventrite. Genitalia with basal lobe as long as paramere, sides parallel in basal 3/4, apical 1/4 rounded to slender apical projection with rounded apex; paramere slender, slightly curved, apex rounded (Fig. 42, 43); penis with basal 3/4 lost, apex briefly attenuate.
Female. Similar to male except head darker yellow; spermathecal capsule short, ramus slightly enlarged, cornu bent medially, apex rounded (Fig. 44).
Variation. Length 2.0 to 2.4 mm, width 1.8 to 2.1 mm, width of lateral yellow portion of pronotum slightly variable, size and position of elytral maculae vary from that described above to nearly contiguous with all intergrades between.
