1 Woznessenskia incurva sp. nov. (Chinese name 弯WdzDzù)

Figs.1 , 6 D

Description. Body large. Head: Face narrow oval, fastigium verticis slightly wider than scapus. Eyes globular, protruding forward and outward. Ocelli small, little distinct. Pronotum broader. Second and third abdominal tergites each with two rows of stridulatory pegs.

Legs: Procoxa with a spine at anterior margin; profemur and mesofemur without spines on ventral surface, protibia and mesotibia with four pairs of long spines and a pair of short apical spurs; dorsal surface of mesotibia with an inner apical spur. Postfemur with 10–11 inner spines and 6–7 outer spines on ventral surface; posttibia with 6–7 spines on both sides of dorsal surface separately, bearing a pair of dorsal apical spurs and two pairs of ventral apical spurs.

Wings elongate, surpassing apex of stretched posttibia. Tegmen: Radius with two branches, both forked near tip; media anterior (MA) free from base; cubitus anterior at base with a single branch that forks into two veins, the anterior branch curving and receiving an oblique connection vein from MA and shortly after dividing again into two parallel branches, i.e. media posterior (MP) and cubitus anterior 1 (CuA1), while the posterior branch (CuA2) not dividing further; cubitus posterior (CuP) undivided, free throughout; with four anal veins, last two with common stem.

Coloration. Body light brown. Fastigium verticis and occiput black, around the eyes with annular black ring; gena beneath eye black, antennal socket with the edge black, antenna black. Eyes brown, ocelli yellow. Pronotum with black stripe along entire margin, with a pair of brown spots near anterior margin, and a pair of brown spots on lateral areas. Spines and spurs on protibia and mesotibia brown; apices of spines and spurs on postfemur and posttibia brown. Tegmina and hind wings transparent, veins dark brown. Apical area of male abdomen with tergites black.

Male. Ninth abdominal tergite moderately protruding posteriorly, with a pair of S-shaped and sclerotized processes. Tenth abdominal tergite with a pair of long projections, apical area each distinctly upcurved with compressed and serrate apex. Cercus short, incurved, apex rounded. Subgenital plate with posterior margin concave, lateral lobes with apices rounded. Styli short, inserted on subapices of lateral margins of subgenital plate.

Female. Seventh abdominal sternite with base comparatively narrow, apical area slightly broad, with median carina, posterior margin almost straight. Cercus long conical, apex rounded. Ovipositor moderately upcurved, apex rounded. Subgenital plate semi-membranous, with many thin transversal riffles, and a median carina, posterior margin rounded.

Measurements (mm). Body: ♂ 21.0, ♀ 22.0; pronotum: ♂ 4.5, ♀ 5.1; tegmen: ♂ 35.0, ♀ 36.0; postfemur: ♂ 13.5, ♀ 14.8; ovipositor: 13.3.

Specimens examined. Holotype: male, Meizihu , Puer, Yunnan, China, 27 July 2007, collected by Fu-Ming Shi & Shao-Li Mao . Paratype: 1 female, same data as holotype .

Etymology. The name of the new species refers to the long projections of male tenth abdominal tergite with apical area distinctly upcurved; from Latin incurv - shows curved upward.

Discussion. The new species is similar to Woznessenskia bimacula Guo & Shi, 2011 , but differs from the latter by: the projections of male tenth abdominal tergite with apical areas distinctly upcurved, inner and apical margins with some teeth; posterior margin of female subgenital plate straight.
