Figure 3 , Map 1 Description. Male. Fastigium verticis about 1.5 times as broad as scape ( Fig. 3A ). Pronotum subsellate, anterior margin slightly projected, posterior margin subtruncate, lateral lobes longer than high, humeral sinus conspicuous ( Fig. 3B–C ). Fore and middle femora unarmed on ventral surface, fore and middle tibiae with 5 pairs of spines on ventral surface; dorsal surface of middle tibiae with 1 inner apical spine. Hind femora with 5–7 inner spines and 6– 7 outer spines on ventral surface; hind tibiae with 5–7 spines on inner and outer margins of dorsal surface separately, 1 pair of dorsal apical spines, 2 pairs of ventral apical spines, and 1 pair of ventral subapical spines. Ninth abdominal tergite slightly curved downwards, lateral margins with 1 pair of comparatively short spine-like processes, which curved downwards. Tenth abdominal tergite short, centre of posterior margin with 1 pair of triangular processes, upcurved, basal area connected, apical area acute ( Fig. 3D–E ). Cerci slightly short, conical. Subgenital plate rectangular, broader than long, basal margin slightly arcuate concave, posterior margin with a concavity in the middle, the lateral lobes triangular ( Fig. 3F ). Female. Appearance of female is similar to male. Seventh abdominal sternite rather large and not membranous, posterior margin concave. Subgenital plate basally broad, with several transverse folds, posterior margin slightly concave in the middle ( Fig. 3J ). Coloration. Body yellowish brown. Eyes blackish brown. Occiput with 1 semicircular black stripe. Middle area of pronotum black, ventral edges of lateral lobes black ( Fig. 3B–C ). Genicular lobes of all legs brown. Fore and middle tibiae with spines blackish brown, their apices yellowish. Spines of hind tibiae brown. Ninth abdominal tergite and processes dark brown ( Fig. 3D–E ). Measurements (mm).

FIGURE 3. Diaphanogryllacris brevispina sp. nov. : A, G. head in frontal view; B–C, H–I. head and pronotum: C, H. dorsal view, B, I. lateral view; D–E, L. apex of abdomen: D. dorsal view, E, L. lateral view; F, J. subgenital plate in ventral view; K. apex of ovipositor in lateral view. A–F. male; G–L. female. Distribution. China ( Yunnan ). Etymology. The new species name is derived from the shorter spines of male ninth abdominal tergite. Discussion. The new species may be related to Diaphanogryllacris laeta ( Walker, 1869 ) , but differs from the latter in: male ninth abdominal tergite with 1 pair of short processes, which curved downwards, not crossed each other; the processes of tenth abdominal tergite obviously triangular, apices close each other. The new species is widely distributed in Yunnan , Southwestern of China , while the type locality of Diaphanogryllacris laeta ( Walker, 1869 ) is in Fujian . From the comprehensive physical geographical regionalization consideration, these localities belong to different physiographic regions. Meanwhile, the two species have significant differences in morphology characteristics. Besides, the new species may be the same species as the material examined by Bey-Beniko (1957) and Gorochov & Woznessenskij (2000) , while the specimens examined by Bey-Beniko (1959) collected from Dinghushan, Guangdong may be belong to Diaphanogryllacris laeta ( Walker, 1869 ) .
