For taxonomic reasons what has been known as Episcia hirsuta (Benth.) Hanst. needs to be united with the species of Nautilocalyx Linden ex Hanst. Unfortunately its basionym, Centrosolenia hirsuta Benth., is the type of Centrosolenia Benth., a generic name that predates Nautilocalyx. The proposed conservation would generate one new combination, but avoid 42 new combinations among the 48 species concerned, including more than 25 species in cultivation.
