Diagnosis.

This species is very similar to T. apicirosea and T. distorta in its external characters. The species can be distinguished by the following characters: the colour of the frons is deeper in T. dichela than that in T. apicirosea , and without reddish pigmentation in T. dichela . In the male genitalia, the uncus is longer in T. dichela than in T. apicirosea and T. distorta ; the socii are composed of two short acute processes on both sides of the tegumen in T. dichela , while these are much longer and digitiform in T. apicirosea and T. distorta ; the process on the dorsal margin of the valvula is much stouter in T. dichela in comparison with T. apicirosea and T. distorta . The diagnostic characters of the female genitalia are given under T. apicirosea .
