Solenidion σ 1of genu I about twice the length of solenidion ω 1of corresponding tarsus. Genual seta cGI and II, and mGI and II, setiform. Solenidia ω 1of tarsi I and II subequal in length.  Differential diagnosis.The new species most closely resembles  T. tenuifoliaPark & Atyeo, 1974in having setae h3lanceolate in males, but can be readily distinguished by the shorter aedeagus reaching only the level of setae g; in  T. tenuifoliathe aedeagus is much longer, reaching the level of the adanal suckers.   Etymology.The specific epithet refers to the length of male aedeagus, shortest than any known species of the genus, and is a noun in apposition.
