Figs. 2 , 6 A

Description. Body large. Face long. Fastigium verticis almost broad as antennal scape. Eyes globular, protruding forward. Ocelli distinct, oval. Pronotum broad and short, anterior margin slightly protruding, 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, their tibiae 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 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 surpassing apex of stretched posttibia. Tegmen: Radius divided RS vein from the middle; 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) not divided further; cubitus posterior (CuP) undivided, free throughout; with four anal veins (fourth indistinct), last two with common stem. Hind wing longer than tegmen.

Coloration. Body yellowish brown, eyes brown, genae under eyes with a thin black stripe separately; fastigium verticis blackish brown; with a thin stripe along edge of antennal socket. Outer surface of antennal scape light, other area blackish brown. Pronotum with a black stripe along edge, lateral lobe each with a light brown stripe. The spines and spurs on all femora and tibiae brown. Male first to eighth tergites each with a transversal black stripe, ninth abdominal tergite black. Tegmen semi-transparent, veins dark brown; hind wing semi-transparent whitish, veins dark brown.

Male. Ninth abdominal tergite with a pair of S-shaped and sclerotized processes on lateral margins. Tenth abdominal tergite with a pair of evidently long and little curved projections; the sclerotized area compressed, long, apex and inner edge near apex serrate. Cercus long conical, incurved, apex rounded. Subgenital plate shorter, posterior margin lightly concave. Styli cylindrical, inserted on lateral margins of subapex of subgenital plate.

Female. Seventh abdominal sternite with length and width almost equal, lateral margins subparallel. Cercus conical, apex acute. Ovipositor moderately upcurved, apex rounded. Subgenital plate short, with many wrinkles, posterior margin rounded.

Measurements (mm). Body: ♂ 19.0–24.0, ♀ 29.0; pronotum: ♂ 4.9–5.0, ♀ 5.2; tegmen: ♂ 36.0–39.0, ♀ 39.0; postfemur: ♂ 16.0–16.1, ♀ 16.0; ovipositor: 13.0.

Paratypes: 1 male, Gaozhai , Xing’an, Guangxi, China, 7 July 2007, collected by Jian-Hua Huang ; 1 male, Xing’an , Guangxi, China, 18 July 2002, collected by Jian-Hua Huang ; 1 male, Gaozhai , Xing’an, Guangxi, China, 20 July 2006, collected by Jian-Hua Huang ; 1 female, Gaozhai , Xing’an, Guangxi, China, 10 July 2014, collected by Jian-Hua Huang. Other specimens: 1 male, Nanling , Ruyuan, Guangdong, China, 5 July 2021, collected by Tao Zhang ; 1 male, Nanling , Ruyuan, Guangdong, China, 8 July 2021, collected by Tao Zhang.

Etymology. The new species is named for the long projections of male tenth abdominal tergite and elongate sclerotized area; from Latin procer- (long).

Discussion. The projection of male tenth abdominal tergite is long, apical sclerotized area is long, tip and inner margin near the tip bear some teeth; female seventh sternite with lateral margins subparallel.
