Description. Male: Body medium to large sized. Fastigium of vertex conical and furrowed, protruding over the edges of antennal base, with a medial longitudinal groove posteriorly. Frons relatively flat, nearly square, and inclined backwards ( Figs. 6A, B ). Surface of pronotum without granular protrusions, the anterior margin slightly arcuate, and the posterior margin blunt and rounded ( Fig. 6B ). Lateral lobes longer than deep, the front and back margins nearly straight ( Fig. 6C ). The apex of tegmina somewhat recurved and pointed, Rs farther from the R than M, which located almost in the middle between Cu and Rs. Sc far from R from the base to the end. The tip of the tegmina pointed. Hind wings shorter than the tegmina and transparent. Both dorsal carinae unarmed. Fore coxae with a spine. Fore femur ventrally with 4–7 inner spines, mid femur ventrally with 6–10 inner spines, hind femur ventrally with 12–15 inner spines. No black stripe on the inner side of the hind femur ( Fig. 6F ). Prosternum unarmed, meso- and metasternum strongly transverse, the former with entire, non-crenellated anterior margin ( Fig. 6D ). Epiproct ovoid, shorter than the length of cerci, and emarginate at the end. Cerci long and conical, with spines at the end and curved inwards ( Fig. 6G ). Subgenital plate gradually narrows toward the end, and the end stalk-shaped. Styli significantly long, thickened at the base, narrowing towards the end, and pointed at the end ( Fig. 6H ).

Female: Larger than male. Generally, the tip of tegmina recurved and pointed ( Fig. 6E , Fig. 8 ), C and Sc area broader than female of other species ( Fig. 8 ). Epiproct longer than wide, oval, with a shallow notch at the end. Styli conical and long. The basal half of the dorsal valves of the ovipositor straight, the distal half narrowing from the base to the end. Base of the ovipositor yellowish-brown, then gradually darkened ( Fig. 6J ). Subgenital plate as in O. nigrisartorius , a triangular wide notch in the center of the rear edge, with rounded corners on both sides ( Fig. 6I ).

Measurements (in mm): Male: SZ 52.44–53.95, PR 7.17–8.06, FW 41.74–46.20, HF 17.62–19.72; Female: SZ 67.63–72.24, PR 9.47–10.10, FW 57.41–59.13, HF 21.77–22.98, OV 32.17–32.34.

Etymology: Species name grandivalvatus relates to the ovipositor being long and robust.

Distribution: Anhui, Guangxi, Sichuan, Zhejiang.
