Diagnosis.

This species is very similar to T. distorta based on the characters of the adult and the male genitalia. However, it can be distinguished from T. distorta by the combination of the following characters: the frons is deep reddish-brown in T. apicirosea but yellowish-brown without reddish pigmentation in T. distorta ; in the male genitalia, the uncus is smaller in T. apicirosea than in T. distorta ; the socii form a right angle and are without process at the base in T. apicirosea , while these are weakly curved and with a triangular process at the base in T. distorta ; the processes on the dorsal and the ventral margin of the valvula are obviously longer in T. apicirosea than in T. distorta ; the juxta is broader in T. apicirosea than in T. distorta . The female genitalia are similar to those of T. dichela in having a slender seventh sternite, but the posterior bifurcate parts are more extended outwards in T. apicirosea ; the ductus bursae is shorter in T. apicirosea than in T. dichela ; the sclerotized part of the ductus bursae is smaller in T. apicirosea than that in T. dichela .
