Diagnosis.

Size (all macropterous): males, length 7.76-8.24, width 2.00-2.08; females, length 7.80-8.40, width 2.16-2.32. Venter of head of both sexes: pale background with a median brown marking and a pair of lateral light-brown, slender stripes. Mesosternum ca. 2.8 × length of metasternum. Male: fore femur moderately incrassate, broad tubercle on basal part indistinct, but with a spot of dense, minute, black setae, flexor side with a row of approximately six long, stiff setae; fore tibia almost straight, slightly curved subapically, exterior side with scattered long, stiff setae (Fig. 13A); abdominal sterna III-VI medially grooved; sternum VII broadly depressed, length subequal to two preceding sterna combined, posterior margin with a median U-shaped notch as deep as one-third of sternum VII length. Male genitalia (Fig. 13C-E): venter of abdominal segment VIII about as long as sternum VII, posterior margin almost straight with dense, yellowish setae; caudal projection of pygophore triangular (in ventral or dorsal view) and directed dorsad (in lateral view), apex narrowly rounded; lateral tubercle of pygophore well-produced, subtriangular, bearing long setae; paramere ovoid; proctiger with lateral tubercles bearing long setae, apex pointed, ventral surface with a sparse patch of long setae. Female: fore femur relatively slender, with a row of 16 long, stiff setae; extensor side of fore tibia with many long, stiff setae along its length; abdominal sternum VII about as long as two preceding sterna combined, posterior margin almost straight, not concealing genitalia; tergum VIII produced posterolaterally.
