Diagnosis. This new species is similar to T. taiwanus Ono, 1977  , but can be separated from the latter by: 1) the shape of the epigynal ridge, 2) the copulatory ducts long and twisted complicated vs. short and simple curved in T. taiwanus  .

Chelicerae, gnathocoxae, labium and sternum yellow. Eye measurements: AME 0.06; ALE 0.13; PME 0.08; PLE 0.11; AME –AME 0.20; AME – ALE 0.20; PME –PME 0.30; PME –PLE 0.40. MOA length 0.38 with front width 0.32 and back width 0.46, Legs yellow. Leg formula: 1243; leg measurements: I: 9.00 (2.70, 3.50, 1.80, 1.00); II: 9.10 (2.80, 3.50, 1.80, 1.00); III: 4.90 (1.50, 2.00, 0.80, 0.60); IV: 5.10 (1.70, 2.00, 0.80, 0.60).
