Tridrepana hypha Chu & Wang, 1988, Acta Entom. Sinica, 31 (2): 206, fig. 4, pl.1: 7. Holotype ♂, China: Yunnan: Lushui. (IZCAS)

Diagnosis. This species is close to T. finita on the wing pattern but larger. Two brownish black spots are present under M 3 and CuA 1 near the lower angle of the cell on the forewing, instead of big grayish brown patches centered by dark spots as in T. finita; the postmedial line is thin and deeply wavy, nearly continuous. In the male genitalia, the two lobes of the uncus are triangular, with the lateral margins oblique, while in T. finita, the lobes of the uncus are nearly quadrate, with lateral sides nearly erect.

Material examined. CHINA, Yunnan: Lushui, Yaojiaping, 2500 m, 4. VI.1981, coll. Wang Shuyong, 1♂ (Holotype) (IZCAS).

Distribution. China (Yunnan).

Remarks. The holotype of this species was dissected by the original authors. In the genitalia slide of the type, the aedeagus has accidentally been placed under the left side of the uncus and is partly covered by the uncus (Fig. 65). Fortunately the features of the aedeagus are recognizable. It is stout and small, lacking a spinose band inside; the cornuti are composed of a bundle of spines.
