48. Prodilis iris Gordon and Hanley , new species

Description. Male holotype. Length 1.7 mm, width 1.3 mm; body elongate oval, elytron with side slightly rounded at middle, wider than pronotal base, widest at middle of elytra. Dorsal surface entirely shiny. Color brownish yellow ( Fig. 585 ); head yellow with lateral margins pale yellow, base of frons and vertex black ( Fig. 587 ); pronotum yellow with median 1/3 black, black area widest anteriorly, narrowed toward base of pronotum; antenna, epipleuron yellow; apical maxillary palpomere dark brown; ventral surface, legs brownish yellow; abdomen brownish yellow. Head punctures large, separated by a diameter or less; pronotal punctures larger than on head, separated by a diameter or less; elytral punctures larger than on pronotum, separated by less than twice a diameter; prosternal, mesosternal punctures large, separated by a diameter or less; metasternal punctures as large as on mesosternum separated by less than a diameter along anterior and lateral margins, smaller, 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 narrow, widest at base and apex, as wide as eye measured at vertex; eye canthus long; apical maxillary palpomere long, slightly widened from base to apex, nearly parallel sided. Pronotum widest at 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 about as wide as long, longer than mesosternum, base arcuate medially, lateral carina slender, extended nearly to base of prosternum. Postcoxal line on ventrite 1 short, rounded, not extended to middle of ventrite ( Fig. 586 ). Apex of ventrite 5 arcuate. Genitalia with slender phallobase, basal lobe shorter than paramere, slender, narrowed from base to emarginate apex; paramere long, slender, curved, apical 1/3 enlarged to rounded apex, without marginal serrations ( Fig. 588, 589 ); sipho robust, straight, apical portion lost ( Fig. 590 ).

Female. Similar to male except female genitalia with spermathecal capsule strongly curved, base enlarged, narrowed from base to slender cornu, apex of cornu rounded.

Variation. Length 1.6–1.7 mm, width 1.2–1.3 mm.

Type material. Holotype male; BRAZIL: Am. (Amazonas), Reserva Ducke , 26km NE Manaus, Hurtado, J.G. C., Corythophora alta . 01.iv.1996, Tree No 68, Tray No. 2, BMNH(E) 2003–84. ( BMNH) . Paratypes; 5, 2, same data as holotype except tree data Tray No. 1, Tree No 104, Tray No. 7 ; 1, same data as holotype but no further data other than locality label ; 2, same data as holotype except host Eschweilera rodriguesiana, Tree No 30, Tray No. 4, 5. ( BMNH) .

Remarks. Prodilis iris is a small, elongate species with entirely pale elytra and very narrow head. These characters will distinguish it from other known Prodilis species.
