Diagnosis. frons and gena dark brown with a light brown sagital band from median ocellus to inferior margin of clypeus; labrum medium brown fading to yellow in the lower extremity (fig. 5D); fore wings stridulatory vein with ca. 77 teeth; subgenital with the posterior margin slightly sinuose (fig. 5I); the apex of pseudepiphallus twisted and truncate, fringe of bristles apical, rows of small denticles absent; copulatory papilla drop-shaped, distinctly depressed, the proximal margin of ventral face broadly invaginated (fig. 15B2).
Description. Male. Head: dark brown (fig. 5A); top of head and occiput dark brown; three ocelli present, the median slightly smaller than lateral ones (fig. 5D); maxillary palpi light brown (fig. 5G); frons and gena dark brown with a light brown sagital band from median ocellus to inferior margin of clypeus, labrum medium brown fading to yellow in the lower extremity (fig. 5D). Thorax: pronotum dark brown (fig. 5C); thoracic sternites as in fig. 5K. Fore wings reaching posterior margin of second abdominal tergite (fig. 5A, F); dorsal field with three harp veins; stridulatory vein with ca. 77 teeth (fig. 16B); lateral field with two parallel veins below angulation. Legs: medium brown except the lighter hind femora (fig. 5L) and dark brown hind tibia; tibia I with only the internal tympanum present (fig. 5J).
