Yang Weicheng, Long Jiankun, Sun Haiyan & Xu Fangling; 1♂, CHINA: Hainan, Jianfengling, 23 April 2014, coll. Long Jiankun ( GUGC).

Variation. Based on the examined specimens, the pygofer caudoventral lobe is long and bluntly narrowed in lateral view and the segment X ventral processes are long, exceeding the apex of pygofer in specimens from Guangxi, Guizhou ( Fig. 195 ), but in Hainan both are relatively short ( Fig. 201 ).

Remarks. This species was described from the holotype (male) from ZSU (Sun Yat-Sen University, Guangzhou, Guangdong, China). It resembles T. vastestyla Wang & Li, 2002 in general appearance, but differs in having the ventral processes of segment X straight ( Figs. 195, 201 ), versus curved in T. vastestyla ( Wang & Li 2002: 2, Fig. 2 ); the paraphysis lateral margins are toothed, without process, and the style is slender with the apex pointed ( Fig. 198 ), whereas in T. vastestyla there are two processes on the paraphysis, and the style is broad, with apex expanded ( Wang & Li 2002: 2, Figs. 4 , 6 ).
