( Figs. 27–29 )

Description. Male. Body median sized. Fastigium of vertex long-ovate, about 2 times as wide as scape. Frons smooth; eyes long-oval, prominent. Fore margin of pronotum projected, hind margin straight. Tegmina rather extending beyond the apex of abdomen, half-transparent; R with 4 branches at apex, not united with M at base; Rs occurred at the middle of R, with 3 branches. Wings transparent, slightly longer than tegmina. Fore and mid tibiae with 5 pairs of spurs, mid tibia without intero-apical spur above. Hind femur armed with 7–8 spines on each side of ventral surface, hind tibia with 6–7 internal and 6-7 external spines on dorsal surface. 9 th abdominal tergite split into two spine-like lobes ( Fig. 28 ); subgenital plate short, broader than long; styli almost as long as subgenital plate, cylindrical.

Female. Subgenital plate narrower at apex, with slightly truncate posterior margin ( Fig. 29 ). Ovipositor straight, slightly longer than hind femur, apex blunt.

Material.

Distribution. China (Hunan, Sichuan, Guangxi, Guizhou).

Diagnosis. This new species appears to be closely related to M. (B.) elongata Li, Liu et Li sp. nov., but its antenna is absolutely infuscate; also the apex of lobes of 9 th abdominal tergite spine-like are not paralleled in it.
