Diagnosis. frons with a sagital straight light brown line; fore wings short, not surpassing first abdominal tergite, the stridulatory vein with ca. 54 teeth; tibia I without tympana; supra-anal plate with posterior margin evenly round (fig. 2H); subgenital plate medium brown laterally, light brown centrally; pseudepiphallus distinctly up-curved; apex of pseudepiphallus thin, with denticles both, on inner and outer side of the invagination, fringe of bristles located distally; pseudepiphallic parameres acute at apex; copulatory papilla finger shaped but acute distally, the proximal margin ventrally triangular (fig. 15C2).
Redescription. Male. Head: black (fig.2A); top of head and occiput blackish; three same-sized ocelli present (fig.2D); maxillary palpi light to medium brown (fig. 2G); frons with a sagital straight light brown line; gena and clypeus medium brown, labrum light brown (fig.2D). Thorax: pronotum medium brown (fig. 2C); thoracic sternites as in fig. 2K. Fore wings short, not surpassing hind margin first abdominal tergite (fig. 2F); apical field vestigial; dorsal field with three harp veins; stridulatory vein with ca. 54 teeth (fig. 16F); lateral field with two parallel veins below angulation. Legs: medium brown; tibia I without auditory tympana (fig. 2J). Abdomen: general color medium brown, darker in the distal tergites, lighter ventrally; supra-anal light brown with two whitish lines on distal pigmented area, posterior margin evenly round (fig. 2H); subgenital plate medium brown laterally, light brown centrally, posterior margin nearly straight (fig. 2I). Phallic Complex (figs. 3D, E, F): pseudepiphallus distinctly up-curved, especially on its posterial third, its main lobe wider at the first third, the apex thin with denticles both, on inner and outer side of the invagination, fringe of bristles apical, dorsally located; pseudepiphallic parameres acute at apex, close to each other; tip of ectophallic fold located posteriorly to the distal margin of the pseudepiphallic parameres; ectophallic apodemes curved. Female: general coloration similar to that of male, pronotum reddish brown (fig. 2B); copulatory papilla pale yellow, finger shaped but acute distally, the proximal margin ventrally triangular (fig. 15C2).
