58. Prodilis alberta Gordon and Hanley , new species

Description. Male holotype. Length 2.7 mm, width 1.8 mm; body elongate oval, elytron with side slightly rounded, wider than pronotal base, widest at middle of elytra. Dorsal surface entirely shiny. Color dark brown ( Fig. 642 ); head black ( Fig. 644 ); pronotum dark brown medially, lateral 1/4 reddish yellow; antenna, legs reddish yellow; mouthparts reddish yellow except apical maxillary palpomere with apical 1/3 brown; epipleuron dark reddish brown; ventral surface reddish brown; abdomen brown. Head punctures small, separated by a diameter or less; pronotal punctures as large as on head, separated by less than twice a diameter; elytral punctures as large as on pronotum, separated by less than twice a diameter; prosternal, mesosternal punctures large, separated by less than a diameter; metasternal punctures on basal and lateral margins small, separated by less than a diameter, smaller and more widely spaced or absent medially; 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, widened from vertex to clypeus, slightly wider than an eye measured at vertex, frons extended well beyond antennal insertion; eye canthus short; apical maxillary palpomere very long, slen- der, longer than remainder of maxilla, feebly widened from base to apex, nearly parallel sided. Pronotum widest anterior to middle, reflexed lateral margin wide, equal in width from base to apex. Epipleuron flat, narrow in basal ½, as wide as pronotal hypomeron, without feeble depressions for reception of femoral apices. Prosternum longer than wide, longer than mesosternum, base slightly arcuate medially, lateral carina slender, extended nearly to base of prosternum. Postcoxal line on ventrite 1 long, rounded, extended 2/3 distance to apex of ventrite ( Fig. 643 ). Apex of ventrite 5 arcuate. Genitalia with basal lobe as long as paramere, widest at middle, narrowed from middle to narrowly, deeply emarginate apex; paramere nearly straight, slender, apical setae long, more than 1/3 length of paramere, paramere without marginal serrations ( Fig. 645, 646 ); sipho short, robust, apex sinuate ( Fig. 647 ).

Female. Similar to male except head not densely pubescent. Female genitalia with spermathecal capsule short, medially curved, widest at base then gradually narrowed to apex of cornu, apex of cornu with large beak.

Variation. Length 2.6 to 2.7 mm, width 1.7 to 1.8 mm.

Type material. Holotype male; BRAZIL: Sao Paulo, R. M. Ihering. ( USNM) . Paratypes; 3, same data as holotype. ( USNM) .

Remarks. This is a distinctive species because of the frontally extended clypeus, male genital paramere with extremely long apical setae, and female spermathecal capsule with a beaked cornu.
