Scythropiodes hamatellus Park et Wu, 1997: 36 . TL: Korea. TD: CIS.

Diagnosis. Adult (Fig. 6) with wingspan 16.5–21.5 mm. Scythropiodes hamatellus is similar to S. jiulianae in appearance by having a similar body color and the same markings on the forewing. Scythropiodes hamatellus can be distinguished in the male genitalia by the subquadrate valva with a long hooked apical process and the absence of the cornutus (Fig. 21); in the female genitalia by the corpus bursae without an appendix bursae and the signa consisting of two elliptical plates with minute denticles (Fig. 35). In S. jiulianae, the triangular valva bears no apical process and the phallus has two cornuti in the male genitalia (Fig. 22); and the corpus bursae has an appendix bursae and the signa consist of two gear-like plates with 9–10 radiated arms in the female genitalia (Fig. 36).
