Figs. 3, 6 B
Description. Body large. Face comparatively long. Fastigium verticis slightly broader than antennal scape. Eyes ovoid, protruding forward and outward. Ocelli distinct, oval. Pronotum broader than long, anterior margin protruding forward, posterior margin rounded. Second and third abdominal tergites each with two rows of stridulatory pegs.
Legs. Procoxa with a spine at fore margin; profemur and mesofemur unarmed on ventral surfaces; protibia and mesotibia with four pairs of long spines and a pair of short apical spurs. Postfemur with 10–11 inner spines and 7–8 outer spines on ventral surface; posttibia with 5–6 spines on both sides of dorsal surface; bearing a pair of dorsal apical spurs and two pairs of ventral apical spurs.
Wings long, reaching apex of stretched posttibia. Tegmen: Radius with two branches, two forked near tip; media anterior free from base; cubitus anterior at base with a single branch that forks into two veins, the anterior branch makes a curvature and receives an oblique connection vein from MA and shortly after divides again into two parallel branches, i.e. MP and CuA1; while the posterior branch (CuA2) does not divide further; cubitus posterior undivided, free throughout, with 4 anal veins, last two with common stem. Hind wings slightly longer than tegmina.
Coloration. Body light brown. Fastigium verticis and occiput black, eyes dark brown, gena light brown. Outer surface of antennal scape light brown, other area brown. Pronotum with a black stripe along whole edge. Spines and spurs on femora and tibiae brown. Tegmen and hind wing semi-transparent; veins dark brown. Male first to seventh abdominal tergites each with a transversal stripe, eighth and ninth tergites black.
Male. Ninth abdominal tergite with a pair of S-shaped and sclerotized hooks on lateral margins. Tenth abdominal tergite with a pair of long slightly incurved projections, apical area compressed, sclerotized area short, apex truncate, serrate. Cercus long conical, little curved, apex rounded. Subgenital plate broad and short, lateral lobes with apices rounded, posterior margin concave in the middle. Styli cylindrical, inserted subapically near the lateral margins of subgenital plate.
Female. Seventh abdominal sternite shorter, posterior margin slightly concave (Fig. 3H). Subgenital plate broad and short, with some transversal riffles, posterior margin slightly concave. Ovipositor whole moderately upcurved, apex rounded. Cercus long conical, apex rounded.
Measurements (mm). Body: ♂ 24.0, ♀ 26.0; pronotum: ♂ 5.0, ♀ 5.1; tegmen: ♂ 38.0, ♀ 39.0; postfemur: ♂ 14.5, ♀ 16.0; ovipositor: 16.0.
Specimens examined. Holotype: male, Babaoshan, Ruyuan, Guangdong, China, 14 June 2019, collected by Tao Wang & Peng Cui. Paratype: 1 female, same data as holotype.
Discussion. The new species is similar to Woznessenskia finitima Gorochov, 2002, but differs from the latter by: the projection of male tenth abdominal tergite with sclerotized area short, tip almost truncate, with several teeth only on the tip; female seventh abdominal sternite short.
It is different from Woznessenskia brevisa Guo & Shi, 2011 by: the projection of male tenth abdominal tergite long, sclerotized area short, tip truncate with several teeth.
Etymology. The name of the new species refers to the apex of projection of male tenth abdominal tergite truncate; from Latin truncate (truncate).
