Diagnosis.

This species differs from its congeners by the following characters: the wing colour of the area outside the medial line is darker than the area inside the medial line; the postmedial line of the forewing is narrow and forms black spots on the veins; the middle part of the postmedial line of the hindwing is strongly curved. In the male genitalia, the uncus is small and raised in T. ruptilinea , which is similar to that of T. correspondens and T. adunca ; the socii are long and digitiform, extending beyond the tip of the uncus; the costa of the valva is narrow at the terminal half and rounded at the tip; the arm between the valvula and the sacculus is longer than the valvula and as long as the costa of the valva, and equipped with several small teeth on the ventral margin, except on the basal half and the subapical part; the sacculus is short and acute at the apex; the vesica of the aedeagus is weakly sclerotized and wrinkled. The seventh sternite of the female is short and bifurcated on the posterior margin; the lamella postvaginalis in the female genitalia are three quadrate lobes, the central one is less sclerotized than the lateral ones; the ductus bursae is very short, narrow, and sclerotized posteriorly.
