Etymology Rathke (1843: 175 gives an etymology as "Wegen der grossen Zahl von bürstenartigen Hervorragungen an beiden Seiten des Körpers habe ich die in Rede stehende Gattung von Würmern nach der vielbrüstigen Diana benannt, die in Ephesus" [Because of the large number of brush-like protrusions on both sides of the body, I have named the genus of worms in question after the many-breasted Diana who lived in Ephesus] [details]
Grammatical gender Feminine. Rathke named the genus after a female, but indirectly by using a modified ending for the city of Ephesus in Greece. Subsequent authors added feminine species-group names. In legend Ephesus was first occupied by (female) Amazons, and it had a strong feminine tradition. [details]
Homonymy Ephesia Rathke, 1843 is permanently unavailable as it is a junior homonym to Ephesia Huebner, 1818 (Zuträge z. Exot. Schmett., 1, 11, 14) in Lepidoptera. [details]
