Diagnosis. This species shares a similar wing pattern and polymorphisms with S. cucullioides and S. signifera; all have basal pale or dark-brown zones which extended to the medial or postmedial lines. This species also resembles S. ferrifera (Walker, 1863) distributed in Malaysia, but its medial line is strongly curved inwards below CuA2, and is vertical to the anal margin in S. ferrifera . The male genitalia are distinguishable by the shape of the membranous webbing of the valva, which lies from the base of the costal lobe in S. macromma, but from the end of the costal lobe in S. cucullioides and S. signifera . In S. macromma the costal lobe is compressed basally (not compressed in S. ferrifera); the cornutus is absent (two groups of cornuti present in S. ferrifera), the uncus is slightly broadened basally, but not in S. ferrifera .
