Li Hu ( GUGC).

Variation. Based on the examined specimens, the paraphysis has the basal digitate process, subapical process and apex always curved toward the same side, but some specimens are mirror images of others ( Figs. 92, 93, 95, 96 ).

Remarks. This species was described from the holotype (male) and three female paratypes from GUGC. It is similar to T. multipars (Walker, 1858) in external appearance, but differs in having the paraphysis excavated subapically with two processes ( Figs. 92, 95 ). In T. multipars the paraphysis has one process basally, tapered to apex ( Figs. 147, 150 ) and the ventral processes of segment X are shorter than the pygofer processes in T. digitata ( Fig. 90 ) and longer in T. multipars ( Fig. 145 ).
