Remarks. Hampson (1896) described S. hyalodisca based on external characters, including variation in wing colour from reddish brown to dark brown. Chu & Wang (1987) described S. fenestra based on two female specimens, which have an identical wing pattern to the females of S. hyalodisca . In addition, the male genitalia of the specimen from the type locality of S. fenestra were found to belong to S. hyalodisca . We therefore synonymize S. fenestra with S. hyalodisca .
