03F40D48FFFA1568E7F21A8EFE1A3AD4.taxon	diagnosis	Diagnosis. Pristonesia is identifiable as a member of the Pristocerinae because the metanotum is developed medially and overlaps the mesoscutellum posteriorly. Among Pristocerinae, it is uniquely identified by having 1) median clypeal lobe large, and usually angulate; 2) hypopygium usually thick medially, 3) posterior hypopygeal margin from weakly emarginated to deeply excavated; 4) harpe with apical projections; 6) cuspis flattened and basally very wide; 7) apex of aedeagal dorsal valve with membranous bubble; 8) cat-whisker-shaped set of setae present on apex of aedeagus; 9) cupula reduced to dorsal-lateral area of the genital ring.	en	Azevedo, Celso O., Colombo, Wesley D.

Forewing with poststigmal abscissa of radial 1 about one third length of pterostigma, 2 r-rs & Rs evenly arched, and not notched where 2 r-rs sector connects to Rs sector; anterior medial and posterior medial 1 flexions lines long, m-cu flexion line straight, claval flexion line weak, r-m flexion line arched. Hind wing with two basal hamuli, and four equidistant distal hamuli. Claws simple, but with tiny median callus, tooth sharp and curved. Metasoma. Opening of spiracle of metasomal segment I elliptical and subdorsal. Tergum I conspicuously longer than tergum II. Sternum II longitudinally bicarinate, carinae diverging posterad. Epipygium wide apically so that its lateral margins almost touch each other ventrally, posterior margin almost straight, without median emargination, not excavated where epipygium folds ventrad. Hypopygium with spiculum long and tip sharp, anteromedial apodeme absent, anterolateral apodeme progressively narrowing apicad into sharp arched mesad tip, anterior margin almost straight medially, posterior margin roundly excavated forming two round lobes without any spine, excavation about one fourth as long as hypopygeal plate, thick median area of inner surface large and slightly progressively narrowing anterad only on anterior third. Genitalia. Harpe with apical margin with two conical expansions, dorsal one longer than ventral one, dorsal margin evenly incurved, wide basally, ventral poorly straight; inner margin of ventral side of gonostipes with rounded median callus, and with few medioapical setae; apical basivolsellar expansion absent; cuspis angled apically, very wide basally, cross-section flat, outer surface convex and smooth, apex sharp, without any membranous extension; digitus cross-section cylindrical, strongly angled and projected basally, otherwise straight, apex squamate and not membranous, base with spine anterad; aedeagus bulging medially in dorsal profile, ventral valve membranous, short, apex aligned with base of cuspis, progressively narrowing apicad, apex sub-blunt, dorsal valve much longer ventral one, its apical membranous extension as long as wide, cat whisker-shaped set of setae long and sparse; aedeagal apodeme arched mesad, ergot tiny; genital ring strongly incurved ventrally.	en	Azevedo, Celso O., Colombo, Wesley D.
