Diagnosis. Ctenane michaeli resembles externally C. labuana but is generally somewhat larger in size (wingspan of C. michaeli is 17–18 mm, that of C. labuana is 13–18 mm), having more greyish forewing ground colour with considerably paler and narrower median fascia and less sharply defined dotted row of postmedial line compared to those of the two related species. In the male genitalia, the new species has conspicuously shorter apically rounded uncus; much longer and narrower tegumen, considerably broader valva with parallel margins; somewhat longer and much narrower, more acute harpe; shorter and rounded vinculum. The uncus is longer, apically pointed in C. labuana ; the valva is medially tapered, and the vinculum is pointed in the related species. In addition, C. michaeli has somewhat shorter, apically more wrinkled aedeagus than those of the related species. Female unknown.

Distribution. The species is known only from Sumatra.
