Woznessenskia Gorochov, 2002 , Entomol. Oboz., 81(2): 318–337. (Entomol. Rev., 82(7): 765–781.) Type species: Woznessenskia finitima Gorochov, 2002 .

Generic diagnosis. Body medium-sized. Distance between antennal sockets equal to width of scape; clypeal suture lost in middle area. Pronotum with noticeable, rather short posterior lobe; fore margin broadly rounded, hind margin straight. Tegmina and hind wings considerably surpassing apices of hind femora. Fore and middle femora unarmed; fore and middle tibiae with 5 pairs of spurs (including a pair of apical spurs) on ventral margin, all spurs long except apical spurs; middle tibiae with an inner upper apical spur; hind femora with 2 rows of spines on ventral margin; hind tibiae with 2 rows of spines on dorsal margin, a pair of ventral spurs near apex, a pair of apical spurs on dorsal margin and 2 pairs of apical spurs on ventral margin; tarsi with well developed blade-like pulvillus. In male, eighth and ninth abdominal tergites enlarged, lateral margins of apex of ninth abdominal tergite with a pair of characteristic S-curved hooks; tenth abdominal tergite partly lost and represented by a pair of narrow sclerites, each sclerite with a long and narrow process, apices of processes with fine denticles; subgenital plate simple, with shallow emargination at apex; styli rather small; genitalia membranous. In female, from eighth to tenth abdominal tergites diminished; ninth and tenth abdominal tergites divided into two parts by membranous area in middle; seventh abdominal sternite forming a pair of roundly angular blade-like lateral folds in posterior part; subgenital plate small, semimembranous, with abundant fine stripes; ovipositor medium length, slightly curved dorsally, with narrow and rounded apex. All margins of pronotum black. Tegmina and hind wings more or less hyaline, with brownish veins. All spines and spurs on legs darkened. Apical abdominal tergites black, except tenth in male, ninth and tenth in female.

Discussion. Woznessenskia Gorochov, 2002 resembles Diaphanogryllacris Karny, 1937 , it differs by the Scurved processes of male ninth abdominal tergite; long and narrow processes of male tenth abdominal tergite; seventh abdominal sternite forming a pair of roundly angular blade-like lateral folds in posterior part and subgenital plate semimembranous in female.
