Diagnosis.

The species is similar to T. acerosus Yang, Zhou & Schillhammer, 2011, T. fujianensis Yang, Zhou & Schillhammer, 2011, and T. diaoluoensis Yang, Zhou & Schillhammer, 2011 in general appearance, but it can be distinguished from them by the apex of median lobe pointed dorsad forming an apical tooth in lateral view, and from T. diaoluoensis also by the aedeagal median lobe with a subapical tooth on the dorsal side. Aedeagal variation (Figs 17 View Figures 15–20 - 32 View Figures 29–32 ) occurs in the apical parts of median lobe and paramere.
