Type material.

Holotype. ♂, China: Yunnan Province, Gongshan County, Dulongjiang Town, Bapo Village , 27.7418 ° N, 98.3561 ° E, alt. 1610 m, 9. VII. 2021, Shengchuan Yang leg.

Diagnosis.

The new species can be distinguished from other congeneric species by the shape of the male epiproct and the ninth abdominal tergite. The ninth abdominal tergite of the male has a long posteromedian process, basal half narrow with a longitudinal median furrow, lateral sides raised into ridges; apical half slightly broadened and curved downwards, with a carina in midline, apex truncate. Male epiproct linguiform, concave on ventral side, apical area slightly protruding.

Description.

Male. Body medium-sized. Fastigium verticis with rostral tubercles, pressed to each other and divided by a narrow and deep furrow, pointing forwards. Eyes ovoid, protruding forwards; lateral ocelli large and circular, occupying basal 2 / 3 of lateral surface of rostral tubercles; median ocellus slightly smaller, oval, located between antennal sockets. Pronotum long, anterior margin straight, posterior margin arcuate; lateral lobe longer than high, ventral margin arc-shaped. Mesonotum and metanotum short, posterior margin of mesonotum arcuate, posterior margin of metanotum straight. Fore coxa with one small spine. Internal genicular lobe of fore femur with one long spine; internal and external genicular lobes of mid femur each with one long spine; hind femur with one inner spine on ventral surface, internal genicular lobe with one small spine. Tibia and hind basitarsus with following armament – ve, vi, ve, v 2 a / de, d ~ 2, d 2 a, ve, ve, v 2 a / d 20 e – 18 i (d 22 e – 20 i), d 2 sa, 6 a / d 3 c, dac. Posterior margin of eighth abdominal tergite angularly projecting. Ninth abdominal tergite with long posteromedian process, basal half narrow with a longitudinal median furrow, lateral sides raised into ridges; apical half slightly broadened and curved downwards, with a carina in midline, apex truncate. Epiproct linguiform, concave ventrad, apical area slightly protruding; paraproct nearly triangular in lateral view. Cercus narrow, conical, apex acute. Subgenital plate transverse and broad, posterior margin straight. Stylus cylindrical, apex rounded, inserted on posterolateral area of subgenital plate. Genitalia membranous. Female. Unknown.

Coloration. Body light brown. Face, fastigium verticis and eyes black; ocelli pale. Thoracic tergites brown.
