Diagnosis. Adult ( Fig. 20B View FIGURE 20 ). 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 View FIGURE 43 ) are characterized by the bulged ventral margin of valval base and the very reduced, minute anellus lobe. The female genitalia ( Fig. 60D View FIGURE 60 ) 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.
