Diagnosis . The new species belongs to the M. chionea species-group, being most closely related to M. chionea ( Hampson, 1911 ) with its pale greyish white forewing ground colour and the broad, almost straight, obtuse pale grey medial band of the forewing. As the species-group comprises several externally indistinguishable species, examination of the genitalia is required for reliable identification. In the male genitalia, M. subchionea differs clearly from M. chionea by its somewhat broader uncus and considerably narrower harpe and the vesica armed with a pair of short but heavily sclerotized, thorn-like cornuti (the vesica of M. chionea bears a peculiar elongate, crest-like, dentate cornutus). The female is unknown.
