Type species: Xulavuna adenoptera n. sp.

Etymology. Name is a free combination of letters proposed by a seven year-old boy (João Francisco Tavares de Mello), son of the second author.

Diagnosis. Fore wing short, slightly longer than pronotum, strongly modified: most of the dorsal field occupied by an antero-internal glandular area, the gland itself conspicuous, visible from the top; lateral field very large, occupying a dorsal position (figs. 10A, F; 14A–D); pseudepiphallus compact distally, sub-tubular, strongly bilobate distally; ectophallic apodeme long.

Description. Male. Head: Dorsum of head flattened, almost leveling the dorsal margin of the eyes, which are large and somewhat projected; inter antennal space broader than antennal scape; three small ocelli present; fifth joint of maxillary palpi with apical truncation occupying about half of the joint length. Thorax: fore wings short, strongly modified, most of the dorsal field occupied by antero-internal glandular area, the gland itself conspicuous, visible from the top; lateral field extended to the dorsum, occupying most of the wing. Metanotal glands absent. Legs: tibia I without tympana, three apical spurs present; tibia II with four apical spurs; femur III robust, tibia III bearing 2–3 teeth on dorso-internal line proximad, then four dorsal spurs, than three apical ones, the median the longest, the same spur configuration on the outer face but with ca. seven teeth; hind basitarsus with ca. six teeth on inner face and five in the outer. Phallic complex (fig. 11A, B, C): elongate, semi-tubular, enlarged at apex; pseudepiphallus strongly bilobate distally, pseudepiphallic paramere 1 (Ps.P1) located ventrally in relation to Ps.P2, acuminate (shaped as a curved needle), Ps.P2 projected, bifurcate at apex and bearing small bristles; rami large; ectophallic sclerite with a pair of very long apodemes, the arc located distally, ectophallic fold with its tip visible from dorsum; endophallic sclerite not discernible (transparent). Spermatophore whitish. Female: apterous, ovipositor well-developed; copulatory papilla compact, with a lobe-shaped projection distad (fig. 15H).
