11. Prodilis lindsey Gordon and Hanley , new species

Description. Male holotype. Length 2.5 mm, width 2.1 mm; body nearly round, wide, elytron with side rounded, wider than pronotal base, widest before middle of elytra. Dorsal surface entirely shiny without trace of microsculpture. Color yellowish red ( Fig. 375 ); head black, apical ½ yellow bisected by deep black emargination, apex of emargination emarginate with yellow ( Fig. 377 ); pronotum entirely black with greenish tint; scutellum black; elytron with basal margin, anterior 2/3 of lateral margin narrowly black, apical ½ of apical declivity black; antenna, mouthparts yellowish brown except terminal maxillary palpomere dark brown; prosternum dark brown; legs black; ventral surface brownish red; abdomen yellowish brown. Head punctures small, separated by a diameter or less; pronotal punctures as large as on head, separated by less than twice diameter; elytral punctures larger than on pronotum, separated by less than 3 times a diameter; prosternal punctures small, separated by less than twice a diameter; mesosternal, metasternal punctures larger than on prosternum, separated by a diameter or less; abdomen with punctures on ventrites 1–3 smaller than on metasternum, separated by less than twice a diameter, punctures on remaining ventrites smaller, separated by about a diameter. Head with sides of frons parallel, nearly twice as wide as eye measured at vertex; eye canthus short; apical maxillary palpomere long, nearly parallel sided, weakly widened from base to apex. Pronotum widest at middle, reflexed lateral margin narrow, equal in width from base to apex, with deep, oblique groove extended from middle of eye posteriorly nearly to posterolateral pronotal angle. Epipleuron slightly descending externally, wide in basal ½, as wide as pronotal hypomeron. Prosternum longer than wide, longer than mesosternum, base strongly produced, apical margin arcuate, lateral carina slender, extended just beyond apex of coxa. Postcoxal line on ventrite 1 long, rounded, extended 3/4 distance to ventrite apex ( Fig. 376 ). Apex of ventrite 5 arcuate. Genitalia with basal lobe slightly longer than paramere, wide, weakly narrowed from base to deeply emarginate apex; paramere straight, wide, widest in basal 3/4, dorsal margin with blunt tooth at basal 1/3 medially, (not seen in image) narrowed to rounded apex, without marginal serrations ( Fig. 378, 379 ); sipho lost.

Female. Unknown.

Variation. Length 2.5 to 2.6 mm, width 2.1 to 2.3 mm. Paratype with yellow elytra and mesosternum.

Type material. Holotype male; VENEZUELA: 1100m., Rancho Grande , Aragua, Feb. 22–23, 1971, H. & A. Howden. ( USNM) . Paratype: 1, same data as holotype except date 18–19, 1971. ( USNM).

Remarks. Prodilis lindsey is a distinctive species recognized by the nearly round body, dorsal color pattern, black legs, and strongly produced prosternum. It bears a superficial resemblance to P. ramona but is dissimilar from that species in nearly all characters other than dorsal color.
