Scythropiodes barbellatus Park et Wu, 1997: 39 . TL: China (Jiangxi) . TD: IZCAS.

Diagnosis. Adult ( Fig. 9 ) with wingspan 13.0–15.5 mm. Scythropiodes barbellatus is similar to S. gnophus in appearance by having a uniformly dark brown forewing with a narrow yellow costal band. It can be separated from the latter in the male genitalia by the valva not being bifurcated distally, the costa having a long leaf-like process at distal 1/4, the transtilla with paired lateral lobes, and the trapezoidal juxta ( Fig. 24 ); and in the female genitalia by the absence of a signum ( Fig. 37 ). In S. gnophus , the valva is bifurcated into two lobes from distal 1/4, the costa lacks a process, the transtilla lacks lateral lobes, and the juxta is inverted triangular in the male genitalia ( Fig. 25 ); and the corpus bursae has a pair of pyriform signa in the female genitalia ( Fig. 38 ).

Female genitalia ( Fig. 37 ). Papillae anales rectangular, setose. Apophyses posteriores about three times length of apophysis anteriores. Eighth tergum with anterior margin protruded rhombically, heavily sclerotized. Seventh tergum and sternum weakly sclerotized posteriorly, with dense microtrichia on lateral sides of distal half, concave on posterior margin. Lamella antevaginalis heavily sclerotized, trapezoidal. Ductus bursae membranous, with dense minute denticles on inner surface, about 1.2 times length of corpus bursae. Ductus seminalis arising from posterior 1/3 of ductus bursae, dilated distally. Corpus bursae ovate, with scattered minute granules on inner surface except two rounded areas bearing dense minute denticles.
