56. Prodilis amelia Gordon and Hanley , new species

Description. Male holotype. Length 2.0 mm, width 1.5 mm; body elongate oval, elytron with side slightly rounded, wider than pronotal base, widest at middle of elytra. Dorsal surface entirely shiny. Color bluish black ( Fig. 632 ); head dark brown ( Fig. 634 ); pronotum dark brown with lateral margin narrowly reddish yellow, anterolateral angle broadly yellow, base broadly reddish yellow; antenna yellow; epipleuron dark reddish brown; ventral surface dark reddish brown; abdomen yellowish brown. Head punctures large, contiguous or separated by a diameter or less; pronotal punctures large, slightly smaller than on head, separated by a diameter or less; elytral punctures larger than on pronotum, separated by a diameter or less; prosternal punctures sparse, nearly absent; mesosternal punctures large, separated by less than a diameter; metasternal punctures large, separated by less than a diameter on basal and lateral margins, smaller and sparse or absent medially; abdomen with punctures on ventrites 1–3 large, separated by less than twice a diameter, punctures on remaining ventrites smaller, separated by about a diameter. Head with frons narrow, elongate, extended anterior to clypeal insertion, not widened from vertex to clypeus, slightly wider than an eye measured at vertex; eye canthus short; apical maxillary palpomere long, widened from base to apex. Pronotum widest at middle, reflexed lateral margin narrow, 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 slender, longer than wide, longer than mesosternum, base slightly arcuate medially, lateral carina slender, extended to apex of procoxa. Postcoxal line on ventrite 1 short, rounded, extended to middle of ventrite ( Fig. 633 ). Apex of ventrite 5 arcuate. Genitalia with basal lobe slightly shorter than paramere, lateral margin briefly widened at basal 1/3, gradually narrowed from basal 1/3 to narrowly emarginate apex; paramere nearly straight, flat in ventral view, narrow in basal ½, slightly sinuate, widened to rounded apex in apical ½, without marginal serrations ( Fig. 635, 636 ); sipho lost.

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; BRAZIL, Nova Teutonia , 27 o 11' B 32 o 23', Fritz Plaumann, (date illegible), Myrtaceae –148 (vulg.guavirova) ( DZUP).

Remarks. This species is distinctive because of the elongate frons, large and dense dorsal punctation, pale pronotal base, bluish black elytron, narrow prosternal process, and unique male genitalia.
