Figs 1 , 6A–B

Diagnosis

Pygofer ( Fig. 1F ) with apex distinctly truncated, ventral margin expanded posteroventrally, forming subquadrate lobe; in dorsal view ( Fig. 1G ), with small preapical inner lobe. Subgenital plate ( Fig. 1F, H ) with small sclerotized dorsal tooth near apex. Style ( Fig. 1I–J ) with knob-shaped apex bearing numerous denticles. Aedeagus ( Fig. 1K–L ) with pair of short and acute apical processes.

Etymology

The specific epithet alludes to the reticulated venation of forewing ( Fig. 1D ).

Material examined

Holotype FRENCH GUIANA • ♂; French Guiana , Kaw Mountain Reserve, 0.5 km Rt. Rd. de Kaw, the hole; 1 Feb. 2008; H. Romack leg.; DNA voucher Entomologia, DZRJ ENT 2812 ; USNM.

Paratype FRENCH GUIANA • 1 ♂; same collection data as for holotype; DZRJ-AUCH #249; DZRJ .

Description

MEASUREMENTS. Total length: male 12.3–12.5 mm (n =2).

COLORATION. Yellow ( Fig. 6A–B ). Crown ( Fig. 1A ) mostly orange, anterior and posterior margins yellow; ocelli yellow. Pronotum ( Fig. 1A ) with anterior three-fourths yellow and posterior fourth dark yellow. Forewing ( Fig. 1D ) yellow, translucent, with dark yellow venation. Legs ( Fig. 6B ) yellow.

HEAD AND THORAX. External morphological characters as in generic description.

MALE TERMINALIA. Sternite VIII ( Fig. 1E ) subrectangular, about 1.5 times as wide as long; lateral margins slightly rounded; posterior margin rectilinear. Pygofer in lateral view ( Fig. 1F ) trapezoidal, length approximately twice maximum height; apex distinctly truncated; macrosetae distributed only near apex, presence of few short and robust setae near apex; ventral margin expanded posteroventrally, forming subquadrate lobe; in dorsal view ( Fig. 1G ), with small preapical inner lobe. Subgenital plate in lateral view ( Fig. 1F ) not produced posteriorly as far as pygofer apex; in ventral view ( Fig. 1H ), subtriangular, basal half of external margin expanded laterally, bearing short setae on apical half; apical half narrowing progressively towards apex; internal margin sinuous; dorsal surface with small, sclerotized tooth near apex; apex rounded. Connective ( Fig. 1I ) approximately three-fifths of length of style; arms broad. Style ( Fig. 1I ), in dorsal view, with apodeme very short, spatulate, and strongly flattened laterally; apophysis elongated, flattened laterally; dorsal margin expanded laterally, forming preapical lamella; in lateral view ( Fig. 1J ), outer lobe indistinct; apex sclerotized, knob-shaped, with numerous small lateral and ventral denticles. Aedeagus ( Fig. 1K–L ) with preatrium reduced; dorsal apodeme developed dorsally, not expanded laterally; shaft tubular and very elongated, curved anteriorly; apex with pair of short and acute processes directed dorsally.

FEMALE TERMINALIA. Female unknown.
