Identification
Distinguishing Orthofidonia from related geometrid requires examination of genitalic structures and pattern details. The three described —O. tinctaria, O. exornata, and O. flavivenata—exhibit subtle differences in wing coloration and pattern that may aid in identification. Specific diagnostic characters for the genus itself are not well documented in available sources.
