41. Prodilis alison Gordon and Hanley , new species

Description. Male holotype. Length 2.2 mm, width 1.5 mm; body oval, elytron with side rounded, wider than pronotal base, widest at middle of elytra. Dorsal surface shiny except elytron with trace of microsculpture. Color black; elytron with median, oval, yellow macula ( Fig. 547 ); head ( Fig. 549 ); antenna, mouthparts, legs yellow. Head punctures small, separated by a diameter or less; pronotal punctures larger than on head, separated by a diameter or less; elytral punctures as large as on pronotum, separated by less than twice a diameter; prosternal punctures small, separated by a diameter or less; mesosternal punctures large, separated by less than a diameter; metasternal punctures basally and laterally as large as on mesosternum, separated by a diameter or less, median punctures small, separated by less than 3 times a diameter; abdomen with punctures on ventrites 1–3 large, separated by a diameter or less, punctures on remaining ventrites smaller, separated by about a diameter. Head with frons densely pubescent, not widened from vertex to clypeus, sides parallel, slightly wider than eye measured at vertex; eye canthus short; apical maxillary palpomere short, widened from base to apex. Pronotum widest at middle, reflexed lateral margin narrow, equal in width from base to apex. Epipleuron flat, wide in basal ½, as wide as pronotal hypomeron, without feeble depressions for reception of femoral apices. Prosternum longer than wide, longer than mesosternum, base weakly emarginate, lateral carina slender, extended anterior to procoxa. Postcoxal line on ventrite 1 short, rounded, extended slightly beyond middle of ventrite ( Fig. 548 ). Apex of ventrite 5 arcuate. Genitalia with phallobase long, slender, basal lobe longer than paramere, widened from base to 3/4, slightly more strongly widened before abruptly rounded apex, apex not emarginate; paramere slender, straight, apex rounded, without marginal serrations ( Fig. 550, 551 ); sipho long, slender, apical 1/3 almost filamentous ( Fig. 552 ).

Female. Similar to male except head not densely pubescent. Female genitalia with ramus of spermathecal capsule enlarged, slender to cornu, apex of cornu with forked beak.

Variation. Length 2.0 to 2.2 mm, width 1.5 mm.

Type material. Holotype male; BRAZIL: Santarem , AccNo. 2966. ( CMNH) . Paratypes; 1, same data as holotype ( CMNH) ; 2, Cl. Fry, Pernam. (Pernambuco, Brazil ) ( BMNH) .

Remarks. This species has a distinctive elytral color pattern as well as characteristic male genitalia.
