The genus Sciota was established by Hulst (1888), with S. croceella Hulst as the type species from Texas, United States of America. This genus is similar to the related genus Nephopterix Hübner, 1825, but can be distinguished by the following characteristics: in the forewing, the R₂ and R₃₊₄ are approaching at base but not connate; in the male genitalia, the juxta is rounded or elongate without lateral lobes; in female genitalia, the corpus bursae is scobinate or with minute sclerites on inner surface. Currently, the genus Sciota comprises 40 species all over the world(Leraut, 2002; Neunzig, 2003; Slamka, 2010), of which four species were reported from the Far East of Russia, two species from South Korea, and five species from Japan(Yamanaka, 2001; Jinbo, 2004-2008; Bae et al., 2008; Kirpichnikova, 2009), and four species have been known in China(Xu, 1997; Li, 2012), the species are as follows: S. adelphella(Fischer von Röslerstamm, 1836), S. fumella(Eversmann, 1844), S. hostilis Stephens, 1834, and S. rhenella(Zincken, 1818). However, only S. adelphella(Fischer von Röslerstamm, 1836) has been reported from NE China. In the present study, we recognize three species of the genus Sciota: S. cynicella(Christoph, 1881), S. fumella(Eversmann, 1844) and S. adelphella (Fischer von Röslerstamm, 1836), of which S. cynicella(Christoph, 1881) is newly recorded from China.

Materials used in this study were collected by light traps in NE China: Heilongjiang, Jilin, and Liaoning Provinces, and NE region of Inner Mongolia. Abbreviations used herein are as follows: TS, type species; TL, type locality.
