Figs. 4 , 6 C

Description. Body large. Head: face comparatively long and narrow. Fastigium verticis slightly broader than scape. Eyes ovoid, protruding forward and outward. Ocelli distinct, oval. Pronotum slightly broader than long. Second and third abdominal tergites each with two rows of stridulatory pegs.

Legs. Procoxa with a spine at anterior margin; profemur and mesofemur with four pairs of long spines and a pair of short apical spurs separately. Postfemur with 10–11 spines on inner margin and 7–8 spines on outer margin of ventral surface; posttibia with 6–8 spines on both sides of dorsal surface; bearing a pair of dorsal apical spurs and two pairs of ventral apical spurs.

Wings reaching apex of stretched posttibia. Tegmen: Radius with two branches; media anterior free from base, cubitus anterior at base with a single branch that forks into two veins, the anterior branch curving and fused with media anterior (MA) for a short distance, then forks, shortly after anterior one (MP) fused with media anterior (MA) for a comparatively long distance, then dividing, while posterior branch (CuA2) not dividing further; cubitus posterior (CuP) undivided, free throughout; with four anal veins, last two with common stem. Both tegmina with the same characters.

Coloration. Body light brown. Fastigium verticis and occiput black. Eyes brown. Antennal socket with the edge brown; gena dark brown; antenna blackish brown. Pronotum with black stripe along whole edge; anterior area of disc with a pair of blackish brown spots; lateral lobe with a comparative broad dark brown spot separately. Spines and spurs on all femora and tibiae brown. First to seventh abdominal tergites with a transversal black stripe separately, male eighth and ninth abdominal tergites black. Tegmen and hind wing semi-transparent; veins dark brown. Projection of male tenth abdominal tergite with apex brown.

Male. Ninth abdominal tergite moderately protruding, with a pair of S-shaped and sclerotized processes. Tenth abdominal tergite with a pair of comparatively shorter projections, subapically upcurved, compressed, inner edge with some teeth. Cercus longer, apex rounded. Subgenital plate slightly broader than long, posterior margin concave. Stylus stout and short, inserted on lateral margin of subapex.

Female. Unknown.

Measurements (mm). Body: ♂ 24.6; pronotum: ♂ 5.0; tegmen: ♂ 35.0; postfemur: 14.0.

Specimen examined. Holotype: male, Huangsha , Lingui, Guangxi, China, 13 August 2016, collected by Shao-Li Mao and Li-Juan Wang.

Etymology. The name refers to MA fusing with MP+CuA1 and MP for a distance separately; from Latin combin- (connected).

Discussion. The new species is similar to Woznessenskia arcoida Guo & Shi, 2011 and Woznessenskia curvi cauda ( Bey-Bienko, 1962), but differs from them by: tegmen MA fused with MP+CuA1 for a short distance, then with MP for a comparatively long distance.
