Redlich originally named the genus Hoeferia (1899). It turned out however, that this name was already given to an Arcoid bivalve by Bittner (1894), rendering it an unavailable junior homonym. This is why in 1902 Cossmann renamed Hoeferia Redlich, 1899 to Redlichia.
Mesodema Whitehouse, 1939, Dongshania Lin in Qiu et al., 1983, and Spinoredlichia Liu, 1975, are considered synonyms of Redlichia.
