21. Prodilis susie Gordon and Hanley , new species

Description. Male holotype. Length 1.5 mm, width 1.0 mm; body elongate oval, elytron with side slightly rounded, wider than pronotal base, widest at middle of elytra. Dorsal surface shiny except elytron with trace of microsculpture. Color black ( Fig. 434 ); head black with irregularly elongate yellow macula on each side next to eye ( Fig. 435 ); pronotum with anterolateral angle brown; elytra with reflexed lateral margin reddish brown; antenna, legs yellow; epipleuron brownish red; mouthparts yellow except apical maxillary palpomere brown; abdomen with terminal ventrite brownish yellow. Head punctures small, separated by a diameter or less; pronotal punctures as large as on head, separated by a diameter or less; elytral punctures larger than on pronotum, separated by a diameter or less; prosternal punctures small, sparse; mesosternal punctures large, separated by less than a diameter; metasternal punctures large apically and laterally, separated by less than a diameter, median punctures small or absent, widely separated; 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 from vertex to clypeus nearly parallel sided, about as wide as eye measured at vertex; eye canthus short; apical maxillary palpomere short, widened from base to apex. Pronotum widest at base, reflexed lateral margin narrow, equal in width from base to apex. Epipleuron flat, narrow, as wide as pronotal hypomeron, without depressions. Prosternum longer than wide, longer than mesosternum, base truncate, lateral carina slender, long, extended nearly to base of prosternum. Postcoxal line on ventrite 1 long, round, extended 2/3 distance to ventrite apex. Apex of ventrite 5 arcuate. Genitalia with basal lobe shorter than paramere, slender, narrowed from base to emarginate apex; paramere slender basally, widened from base to rounded apex, without marginal serrations ( Fig. 436, 437 ); sipho long, slender ( Fig. 438 ).

Female. Head black. Female genitalia with spermathecal capsule short, basal ½ enlarged, apical ½ slender, cornu apically rounded ( Fig. 439 ).

Variation. None observed.

Type material. Holotype male; BRAZIL: Rio de Janeiro, Hort. Bot. Quinta, 3–X–1985, T. Henry. ( USNM) . Paratypes; 4, same data as holotype. ( USNM) .

Remarks. This little species is characterized in males by the uniquely maculate head and by genitalia structure.
