Remarks
In 1999,
Mark Parsons et al included
Antepirrhoe as a synonym of
Eustroma (in Malcolm Scoble's catalog
Geometrid Moths of the World).
In 2001, Sei-Woong Choi (see References below) reinstated Antepirrhoe as a valid genus, based on cladistic analysis of 51 morphological characters compared among 47 related species. Three species of Antepirrhoe occur in North America, whereas all Eustroma species are restricted to Eurasia.
