19. Pentilia estelle Gordon and González , new species

Description. Male holotype. Length 2.2 mm, width 2.0 mm; dorsal surface shiny. Color black; head yellow with brown clypeal apex; pronotum yellow with small, basomedian brown macula; elytron with lateral margin narrowly, obscurely blackish red ( Fig. 100 ); venter black except mouthparts, legs yellow; epipleuron dark reddish brown; abdomen with lateral 1/4, ventrite 5 yellow, medially dark brown. Head punctures large, separated by less than a diameter; pronotal punctures as large as on head, separated by a less than to twice a diameter; elytral punctures as large as on pronotum separated by less than to 3 times a diameter; prosternum with small punctures separated by less than a diameter; mesosternum with punctures larger than on prosternum, separated by about a diameter; metasternum with punctures as large as on mesosternum, separated by less than to twice a diameter in median 1/3, absent in lateral 1/3; abdominal ventrites 1, 2 with small punctures separated by about 1-3 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. 101 ); eye canthus long, about 3/4 width of eye. Prosternum with lateral carina straight, extended 1/2 distance from apex to base of prosternum. Epipleuron strongly descending externally. Postcoxal line on basal abdominal ventrite curved, extended 3/4 distance to rear margin of ventrite. Genitalia with penis guide long, basal lobe as long as paramere, sides nearly parallel in basal 2/3, gradually narrowed to rounded apex in apical 1/3; paramere slender, curved, apex rounded ( Fig. 102, 103 ); penis long, slender, apex extremely attenuate, attenuate portion at least as long as 1/2 length of penis; basal capsule sinuate, inner arm short, narrow, weakly bent, outer arm short, curved, apex V-shaped, rounded ( Fig. 104 ).

Female. Similar to male except head brown, pronotum black with lateral 1/4 yellow; spermatheca not examined.

Variation. Length 1.9 to 2.2 mm, width 1.8 to 2.0 mm.

Type material. Holotype male; Port-of-Spain, Trinidad, BWI, 8-28-37, KA Bartlett, PR 1945, 37-23363. ( USNM) . Paratypes 8, 1, Icacos , Trinidad, BWI, February, 1947 ; 1, Dept. Agr. grounds, Port-of-Spain, Trin, Oct. 24, 1918. A-818, Harold Morrison .; 1, St. Augustine , Trinidad, II-1-’39, P.R. #2247, K. A. Bartlett ; 1, Port-of-Spain, Trinidad BWI, 8-28-’37, KA Bartlett, PR 1945, 37-22363 ; 1, Trinidad, BWI, St. Augustine , Aug. 28.’37, Asterolecanium miliaris sp, 1963.37-24924, KA Bartlett ; 1, St. Augustine , Trinidad II. 1.’39, P.R. #2247, K.A. Bartlett. ( USNM) .

Remarks. The male genitalia with basal lobe are quite different from those of P. nadine , also a Trinidad species. The mostly yellow male pronota also are of value in recognition as is the narrow, reddish, lateral elytral margin.
