Cryptophlebia chaomorpha (Meyrick) is closely related to C. isomalla (Meyrick) and C. batrachopa Meyrick (= C. colivora Meyrick), new synonym, and the three form a species group. If one wishes to separate this group from the remaining species of Cryptophlebia, Diakonoff's Metriophlebia should be used.
