Distribution. China (Guangxi, Fujian, Zhejiang, Guizhou, Guangdong, Taiwan).

Material examined. 1♂, CHINA: Guangxi, Yuanbaoshan, 16 July 2004, coll. Yang Maofa; 1♂, CHINA: Guizhou, Leigongshan, 2 Aug. 2004, coll. Xu Pian; 1♂, CHINA: Guizhou, Leigongshan, 13–14 Sep. 2005, coll. Li Zizhong & Zhang Bin; 1♂, CHINA: Guangdong, Nanling, 7–9 Aug. 2006, coll. Yang Zaihua; 1♂, CHINA: Fujian, Wuyishan, 3 Aug. 2009, coll. Zheng Yanli ( GUGC).

Variation. Based on the literature and the examined specimens, the number of style processes varies from four ( Nielson 1977: 36, Figs. 78–79 ) to three ( Figs. 209, 211–213 ), the latter with two processes apical and the third at apical 1/3 ( Figs. 209, 211, 213 ) (Fujian, Guangxi, Guangdong) or near the middle ( Fig. 212 ) (Guizhou).

Remarks. This species was placed in the genus by Nielson (1977) and described from the holotype (female) from SMTD (Staatlische Museum für Tierkunde, Dresden, East Germany). It is similar to T. projecta (Distant, 1908) in external morphology and certain male genital features, but can be distinguished by the three or four processes on the style ( Figs. 209, 211–213 ; Nielson 1977: 36, Fig. 79 ). In T. projecta the style is bifurcate medially and the inner branch has many teeth ( Fig. 221 ). In T. philagroides the segment X ventral processes reach the apex of the pygofer lobe ( Fig. 206 ), whereas they are shorter than the pygofer lobe in T. projecta ( Fig. 218 ).
