Types.

Holotype: ♂ (SMF), Myanmar, Chin State, Nat Ma Taung National Park, Road S of Nat Ma Taung Summit, Pristine Primary Forest, 21°10.125'N, 93°54.892'E, 2543 m, 16.V.2014, P. Jäger leg.

Etymology.

The species is named in honor of Peter Jäger (Frankfurt am Main, Germany), a prolific spider taxonomist.

Diagnosis.

Males of T. peterjaegeri sp. nov. resemble those of T. ganlan sp. nov. but can be distinguished by the narrow oblong shape of the bulb (Fig. 6C) (vs. elliptical in T. ganlan sp. nov. (Fig. 8C)), the embolus is half the length of the entire bulb (Fig. 6C) (vs. embolus almost equal in length to the entire bulb in T. ganlan sp. nov. (Fig. 8C)), and the embolus is thin and straight (Fig. 6C) (vs. embolus is thicker and curved in T. ganlan sp. nov. (Fig. 8B)).
