Diagnosis. fore wings surpassing the fifth abdominal tergite, stridulatory vein with ca. 75 teeth; abdominal sclerite I strongly modified, almost completely fused and concealing sclerite II, also bearing a complex glandular structure; subgenital plate U-shaped; pseudepiphallus apex truncate, near each other; ectophallic apodeme long, straight, shaped as broken rod united, each peace linked to its other half by a small unpigmented connection point, the distal portion narrower than the preceding one; copulatory papilla depressed, longer than wide, dorso-ventrally angle-curved.
Description. Male: Head: Dorsum of head rounded, vertex of head flattened, largest width of the head in the region of the eyes, infero and external margin of eyes sub straight; inter antennal space narrower than antennal scape; three same-sized ocelli, the median elliptical; maxillary palpi with the fifth joint thumb-shaped. Thorax: pronotum wider than long, covered of bristles, anterior margin slightly concave, posterior slightly convex, lateral lobes short with inferior margin straight, broadly curved on hind angle; thoracic sternites as in fig. 12K. Fore wings trapezoid, hind margin round, surpassing the fifth abdominal tergite, mirror absent; lateral field with two parallel veins below angulation, stridulatory file with ca. 75 teeth. Legs: tibia I bearing three apical spurs, only the internal tympanum present; tibia II with three apical spurs; femur III robust, tibia III with 3/3 very small denticles, 3/3 dorsal spurs and 3/3 apical ones. Abdomen: abdominal sclerite I strongly modified, almost completely fused and concealing sclerite II, also bearing a complex glandular structure (fig. 14E, F, G); supra-anal plate short, rounded distally; subgenital plate U-shaped, with bristles. Phallic complex (figs. 13A, B, C): rather short; pseudepiphallus bilobate distally, the lobes short, juxtaposed, truncate at apex; pseudepiphallic paramere rounded, located internally, the tip of each one visible from dorsum; ectophallic apodeme long, straight, shaped as broken rod united, each peace linked to its other half by a small unpigmented connection point, the distal portion narrower than the preceding one; endophallic sclerite elongate, straight, the proximal extremity located at the level of the interface between the main lobe of pseudepiphallus and the rami. Female: apterous, ovipositor well-developed; copulatory papilla depressed, longer than wide, dorso-ventrally angle-curved.
