Diagnosis.

The shape of aedeagus of T. jakli sp. n. is somewhat similar to that of T. ferrugata (Blanchard, 1850) from the Himalayas; the left paramere of the new species is, however, distinctly longer and distinctly split into two short filiform branches at apex.

Etymology.

The new species is named after its collector, St. Jakl (noun in genitive singular).
