During the preparation of the “Online taxonomic facility of geometrid moths” (see Rajaei et al. 2022), it was noted that Rindgea Ferguson, 2008 is a junior homonym of Rindgea Johnson, 1993, a New World genus in the butterfly family Lycaenidae. Rindgea Johnson, 1993 is currently considered as a junior synonym of Nicolaea Johnson, 1993 (Lamas 2004).

As requested by the International Code of Zoological Nomenclature (ICZN 1999, Article 60), (Rajaei et al. 2022) proposed Frederickia nom. n. as a new replacement name for Rindgea Ferguson, 2008, respecting the original intent behind the naming of this genus by Ferguson (2008).
