Description.

Male. Slim and slender, withered-grass-like (Fig. 1A ). Three ocelli large and hump (Fig. 4A ). Fore femur approximately as long as fore coxa, with 4 posteroventral, 4 discoidal, 17 anteroventral spines; claw groove lying basally than middle of fore femur. Fore tibia about half as long as femur, with 5 posteroventral, 10 anteroventral spines and 1 strong tibial spur. Wings hyaline and iridescent, a little shorter than body; fore wings long and narrow, hind wings broad. Cerci flat, wide, lanceolate, with distal joints gradually becoming longer distad (Fig. 5C ).

External genitalia (Fig. 6A ) small; left phallomere narrow, long, with finger-like process paa and about 12 thick bristles on the afa; ventral phallomere with a robust short sharp spd.

Female similar as male, but larger, stronger, and wingless.

Male measurements (Length in mm). Body: 34.60-35.05; head: 7.10-7.14; pronotum: 5.90-5.95; fore coxae: 2.90-2.95; fore femora: 3.18-3.22; fore tibiae: 2.39-2.41; middle femora: 3.57-3.60; hind femora: 6.65-6.70; forewing: 14.05-14.10; hind wing: 15.33-15.38; cercus: 8.70-8.75.
