24. Prodilis plagioderina (Gorham)

Neaporia plagioderina Gorham 1897: 218 .

Prodilis plagioderina: Korschefsky 1931: 110 ; Blackwelder 1945: 444.

Description. Male. Length 3.4 mm, width 2.8 mm; body rounded, elytron with side rounded, wider than pronotal base, widest before middle of elytra. Dorsal surface entirely shiny without trace of microsculpture. Color black with faint bluish tint ( Fig. 452 ); head yellow except base of frons and vertex black ( Fig. 454 ); pronotum yellow except dark brown, rounded median macula; antenna, legs, yellow; epipleuron yellowish brown; mouthparts yellow except apical ½ of apical maxillary palpomere brown; venter yellow; abdomen yellow. 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 larger than on pronotum, separated by less than twice a diameter; prosternal, mesosternal punctures large, separated by a diameter or less; metasternum with punctures as large as on mesosternum, distributed throughout, separated by a diameter or less; abdomen with punctures on ventrites 1–3 large, separated by 1 to 3 times a diameter, punctures on remaining ventrites smaller, separated by about a diameter. Head with frons widening from vertex to clypeus, slightly wider than 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 descending externally, as wide as pronotal hypomeron. Prosternum wider than long, about same length as mesosternum, base truncate, lateral carina slender, extended anterior to apex of procoxa. Postcoxal line on ventrite 1 long, rounded, extended 2/3 distance to apex of ventrite ( Fig. 453 ). Apex of ventrite 5 slightly emarginate. Genitalia with basal lobe longer than paramere, slender, sides weakly narrowed from base to emarginate apex; paramere slender, curved, apex rounded ( Fig. 455, 456 ); sipho long, robust, sinuate in apical 1/3 ( Fig. 457 ).

Female. Unknown.

Variation. None observed.

Type locality. PANAMA: Bugaba.

Type depository. BMNH.

Geographical distribution. Panama.

Specimens examined. 2. Holotype male ( BMNH); 1, Bugaba , Panama. ( USNM).

Remarks. Prodilis plagioderina is recognized by its large size, round body form; and mostly yellow pronotum with median dark macula. The BMNH holotype is a male labeled “Bugaba, Panama. Champion./ Neaporia plagioderina Gorham (handwritten)/sp. figured./B.C.A., Col., VII. Neaporia plagioderina Gorh (handwritten)/ HOLOTYPE (orange bordered disc)/ HOLOTYPE Neaporia plagioderina Gorh.
