Wingspan 9.0− 12.5 mm . The forewing of T. oxygramma is much darker than those of related species and lacks the dark suffusion or streaks on dorsum. The male genitalia ( Fig. 43E, M ) are characterized by the bulged ventral margin of valval base and the very reduced, minute anellus lobe. The female genitalia ( Fig. 60D ) closely resemble those of T. lata , but can be differentiated from the species by having a larger colliculum situated close to ostium bursae, the ductus bursae nearly as long as corpus bursae and the signum situated at middle of corpus bursae. Distribution. China ( Hainan , Yunnan ), India . Remarks. This species is recorded from China for the first time.
