Odites approximans Caradja, 1927: 33 . TL: China (Beijing) . TD: MGAB. Odites choricopa Meyrick, 1931: 74 .

Scythropiodes choricopa (Meyrick) : Lvovsky, 1996: 650. Scythropiodes approximans (Caradja) : Park & Wu, 1997: 35.

Diagnosis. Adult ( Fig. 4 ) with wingspan 17.5–24.0 mm. Scythropiodes approximans is similar to S. tribula in appearance by having a similar forewing pattern. It can be separated from the latter by the valva that is suddenly produced from distal 1/3 to a slender finger-like process in the male genitalia ( Fig. 19 ), and by the gear-like signum with 8–11 radiated arms but without any denticles in the female genitalia ( Figs 34 a–c). In S. tribula , the valva is slightly narrowed from distal 1/3 and has a short apical spine in the male genitalia ( Fig. 20 ); and the ovate signum has denticles but lacks radiated arms in the female genitalia ( Park & Wu 1997: 49–49a).
