Thagria bispina Zhang 1990: 97 –98, Fig. 95; Li & Wang 1991: 276; Li 1993: 31; Zhang 1994: 14 –15, Fig. 5, original; Nielson, 2013: 81

Distribution. China (Guangxi, Guizhou).

Material examined. 1♂, CHINA: Guizhou, Libo, Maolan, coll. Chen Huimin; 3♂, CHINA: Guizhou, Libo, Dongtang, 22 May 1995, coll. Chen Xiangsheng; 1♂, CHINA: Guizhou, Libo, Banzhai, 25 May 1998, coll. Li Zizhong; 1♂, CHINA: Guizhou, Libo, Wengang, 22 July 2011, coll. Zheng Weibin (GUGC).

Variation. Based on the examined specimens, the two basal processes of paraphysis are mirror images of each other, Figs. 33–34 (Guizhou, Maolan), Figs. 36–37 (Guizhou, Wengang).

Remarks. This species was described from the holotype (male) from NWAFU (Northwest A&F University, Yangling, Shaanxi, China). It is similar to T. birama Zhang, 1994, T. conica Zhang, 1990 and T. projecta (Distant, 1908) in general appearance, but differs in having two processes on the base of the paraphysis (Figs. 33, 36), while the other three species lack such process (Figs. 23, 57, 221); T. bispina has the style entire, with one subapical spine and the apex hooked (Fig. 33), whereas the style is bifurcate medially in T. projecta (Fig. 221), and apically in T. conica (Fig. 57) and T. birama (Fig. 23).
