Material examined. Two males and two females, PR China: Guizhou, Jiangkou (Fanjingshan Mountains, Fig. 6, a), 27°52′20.8′′N, 108°47′5.5′′E, 300 m, 30 July 2016, coll. Ling-Sheng Zha. Two junior nymphs (one male and one female), PR China: Hunan, Dongkou (Xuefengshan Mountains, Fig. 6, b), 27°33′N, 110°39′E, 800–900 m, 12 September 2016, coll. Ling-Sheng Zha.
Notes. Phaesticus moniliantennatus was originally described from Fujian, PR China (Günther, 1940). Podgornaya (1991) recorded the species from northern Vietnam. The species is similar to F. daqingshanensis from Guangxi (Jiang & Zheng, 1998), F. dentifemura from Guangxi (Zheng, 2003), F. guizhouensis from Guizhou (Wang, 1992), F. nankunshanensis from Guangdong and Guangxi (Zheng, 2005), and F. wuyishanensis (= F. chishuiensis, = F. nigrifemura, = F. nigritibialis) from Guangxi, Guangdong, Guizhou, Fujian, and Hunan (Ding et al., 2017). Their main differences from these allied species are: 1) width of vertex (generally 0.9–1.3 time as wide as one eye, and generally in females slightly wider than in males); 2) prozonal carinae and interhumeral carinae (invisible, barely visible, or visible; inconspicuous); 3) hind pronotal process (varies from nearly reaching the apices of hind femora to surpassing the middle of hind tibiae, in males generally longer than in females); and 4) hind wings (similar to hind process, vary from nearly reaching to slightly surpassing the apex of hind process, in males generally longer than in females). However, all these differences are minor, which is why it is not logical to separate them into different species. Geographically, they were all reported from adjacent regions (northern Vietnam, Guangxi, Guangdong, Guizhou, Fujian, Hunan). Ding et al. (2017) described the specimens from Guizhou as F. wuyishanensis, and synonymized F. chishuiensis, F. nigrifemura, and F. nigritibialis with F. wuyishanenis; Skejo (2017) identified these specimens as P. moniliantennatus, and considered F. dentifemura, F. nankunshanensis, F. nigrifemura, and F. nigritibialis as synonyms of P. moniliantennatus. For these reasons, we combined these allied species into one species.
