Costal crossveins 23, 1-13 brown, 14-23 yellowish-green; pterostigma yellow without crossvein; R-Rs crossveins 13, 1- 4 brown proximal to half R vein, 5-13 wholly yellow; branches of Rs 11, yellowish-green; Psm-Psc 6, yellow.

In abdomen, 7 th tergite longer than 8 th tergite ( Fig. 5b ). Ectoproct small and leaning, tapered off on lower half. 8+9 sternum slender. Gonarcus divided on median and two slender lateral lobes ( Fig. 5c, d ). Entoprocessus arc-shaped. Pseudopenis bifurcated on median. Tignum and gonapsis as showed in Fig. 5e&f .
