71. Prodilis bartletti Gordon and Hanley , new species

Description. Male holotype. Length 2.2 mm, width 1.6 mm; body elongate oval, elytron with side rounded, wider than pronotal base, widest at middle of elytra. Dorsal surface entirely shiny. Color black; head black ( Fig. 703 ); elytron with large, irregularly oval reddish yellow macula located medially in anterior ½, macula extended from posterior to humeral callus to apical declivity, narrow at apex becoming widest at declivity ( Fig. 701 ); antenna, mouthparts yellow; abdomen dark brown. Head punctures small, separated by less than a diameter; pronotal punctures larger than on head, separated by a diameter or less; elytral punctures larger than on pronotum, separated by a diameter or less; prosternal, mesosternal punctures coarse, separated by about a diameter; metasternal punctures as large as on mesosternum, separated by less than a diameter anteriorly and laterally, smaller and more sparse medially; abdomen with punctures on ventrites 1–3 smaller than on metasternum, separated by a diameter or less, punctures on remaining ventrites smaller, separated by about a diameter. Head with frons densely pubescent, parallel sided from vertex to clypeus, eye slightly wider than frons 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; hypomeron deeply excavated. Epipleuron flat, wide in basal ½, as wide as pronotal hypomeron, without depressions for reception of femoral apices. Pronotal hypomeron excavated. Prosternum longer than wide, longer than mesosternum, base arcuate, lateral carina slender, extended anterior to procoxa. Postcoxal line on ventrite 1 short, arcuate, extended to middle of ventrite ( Fig. 702 ). Apex of ventrite 5 arcuate. Genitalia with phallobase long, slender, longer than paramere, side sinuate to bluntly rounded apex; paramere slender, straight, apex rounded, without marginal serrations ( Fig. 704, 705 ); sipho slender, long, apical ½ filamentous ( Fig. 706 ).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; Trinidad, PofSpain, K. A. Bartlett, Pr 2239 I.1 ’39 ib Aserolecanium spp. ( USNM).

Remarks. This is another species difficult to assign to a genus, but is tentatively placed in Prodilis with other species with an excavated pronotal hypomeron. It is distinguished by dorsal color pattern and Trinidad type locality.

Etymology. This species is named for the collector of the type series.
