Holotype: male; type locality: Jinyunshan, Chongqing, China; location of type specimen: Zoologiacal Institute of Shaanxi Normal University.

Redescription. Stridulatory file weakly curved, 1.9 mm long, with about 126 teeth. Male genitalia sclerotized, comparatively shorter, visible in dorsal view

Discussion. The left tegmen together with its stridulatory file are very similar to the other species of the genus. Male genitalia sclerotized, shorter. Therefore, we transfer the species to the genus Acometura. The species differs from Acometura forcipata Liu, Zhou & Bi, 2008 in: body brown; subapical area of male cerci concave ventrad, broadened, apices with 1 small apical spine; female subgenital plate semicircular, basal margin slightly excavate, posterior margin obtusely rounded, median carina obviously raised.
