Prosternum unarmed. Male stridulatory file and left stridulatory area damaged in the only available male specimen; mirror approximately rectangular, with rounded corners. Tenth tergite in both sexes with two small, roughly triangular lobes; male cercus straight, slightly thickened subapically, with small sub-basal tooth internally ( Fig. 32 E); female cercus simple, elongately conical, somewhat curved. Male titillators elongate, flattened, with subapical, round dilatations, apices truncated ( Fig. 32 G). Male subgenital plate with deep, rectangular incision, resulting in styli being situated on long, widely separated lobes; styli long and thin; female subgenital plate wider than long, with minute, triangular lobe on its hind margin. Ovipositor short, sickle-shaped, about as long as half of hind femur (ratio ovipositor/hind femur 0.53) ( Fig. 32 F).
