Supplementary description. Male. Posterior margin of tenth abdominal tergite with a posterior process, base robust, apical half divided into two branches, which curved outwards. Cercus elongate, basal half cylindrical, possessing a small projection on internal margin of ventral surface near middle area; apical half compressed, and subapex slightly expanded dorsally, apex with a small notch. Subgenital plate with base slightly broad, median area with a longitudinal carina, posterior margin rounded. Styli conical and apices rounded, inserted on lateral margins of subgenital plate.
Female. Cercus short and conical. Basal margin of subgenital plate nearly straight, middle area slightly broad; posterior margin feebly concave. Ovipositor long and straight, basal area stout, slightly constricted near the middle, dorsal valvulae with apices acute and ventral ones with apices hook-shaped.
Material examined. 2♂, Chawanggu, Mangshan, Yizhang, Hunan, 20 August, 2018. coll. Yanqing Li; 1♂, Chawanggu, Mangshan, Yizhang, Hunan, 21 August, 2018. coll. Yanqing Li; 1♂, Chawanggu, Mangshan, Yizhang, Hunan, 23 August, 2018. coll. Yanqing Li; 1♀, Chawanggu, Mangshan, Yizhang, Hunan, 20 August, 2018. coll. Yanqing Li.
Measurements (mm). Body: ♂ 7.8–8.5, ♀ 8.5; pronotum: ♂ 2.5–3.5, ♀ 3.3; tegmen: ♂ 10.1–10.5, ♀ 12.5; hind femur: ♂ 8.3–8.8; ovipositor: 9.1.
Discussion. Liu & Zhang (2000) described this species based on a single male specimen (holotype: male; type locality: Qiongzhong, Hainan). Wang (2020) examined the type specimen and concluded that the holotype has a broken distal portion of subgenital plate, proposing Xizicus furcutu s Jiao & Shi, 2014 as a synonym of Xiphidiopsis (Euxiphidiopsis) quadridentata (Liu & Zhang, 2000). Our team collected several specimens of this species from Mangshan, Hunan Province in 2018. This study describes the female of the species for the first time.
