description: Adenopygus Bolfarini & de Mello, n. gen.
(Figs. 1–4)
Type species: A. heikoi, n. sp.
Etymology. The specific epithet alludes to the glandular condition of the supra-anal plate of the male.
Diagnosis. (Based mainly on comparisons with specimens of Ottedana). Maxillary palpi short and robust, the last joint with a large apical truncation; male supra-anal plate with an unpigmented, nearly glabrous, membranous, area in central portion; male paraprocts without a cavity on ventral surface; male cerci without clasping structure; dorsum and laterals of the phallic complex covered by scutum-shaped membranous hood; pseudepiphallic parameres 1 and 2 without inflatable membranous structure (cf. de Mello & Andrade, 2003 for this character). Ovipositor straight.
Description. Male: body sub-cylindrical, pubescent; back of head and fastigium with bristles and micro pilosity, its greatest width at eye level; inter-ocular space slightly flattened, oblique in lateral view; eye without unpigmented area (Fig. 1 E); three ocelli present; maxillary palpi short, last joint with robust apical truncation occupying about half of its length (Fig. 1 D). Pronotum disk wider than long, covered with bristles, its anterior margin slightly concave, posterior margin straight; lateral lobes with straight ventral margin, antero-ventral angle of nearly 90 degrees, postero-ventral angle rounded; fore wings short, not reaching posterior margin of metanotum, non-glandular, covered with bristles on posterior half and bearing trace of single longitudinal vein (Fig. 1 F, G), internal margins juxtaposed, lateral margins gradually merging into posterior margin; dorsum of metanotum with granular area; tibia I armed with 2 ventral apical spurs, one internal and one external; tibia II with 4 apical spurs; tibia III with 4 dorsal spurs on both sides, 3 apical spurs on each side, of which median spur is the longest on the internal face and upper spur is the longest on the external. Supra-anal plate broad, glandular, densely haired (Fig. 1 L and 2K-M), paraprocts horizontally oriented, devoid of cavity on ventral face to accommodate pseudoepiphallic lateral spines (condition present in Ottedana); cerci short, without claspers. Phallic complex (Fig. 3) with membranous dorso-lateral cap covering much of pseudepiphallus; point of contact of pseudepiphallic parameres 1 and 2, in posterior view, without spherical membranous structure; ectophallic apodemes short with broad, well developed arch, ectophallic fold short; endophallic sclerite small, bearing crest-shaped dorsal apodeme only. Female: similar to male but larger and less cylindrical; apterous; dorsum of head more rounded in lateral view; supra-anal plate not glandular; paraprocts not horizontal; posterior margin of subgenital plate with wide shallow concavity; ovipositor straight, apical valves small.
