Diagnosis. This species is characterized by the forewing having a broad yellowish white dorsal band. Ypsolopha dentella is similar to Y. varidentella sp. nov., but can be separated by the yellowish white head and thorax (Fig. 41), the arched uncus and the longer phallus about 1.4 times length of the valva in the male genitalia (Fig. 141), and the lamella postvaginalis composed of two sclerotized parallel bands in the female genitalia (Fig. 186). In Y. varidentella sp. nov., the forewing has a grayish brown dorsal band, and the head and the thorax are gray or grayish brown (Fig. 43), the uncus is triangular and the phallus is slightly longer than the valva in the male genitalia (143), and the lamella postvaginalis is V-shaped in the female genitalia (Fig. 188).
