Etymology: Andromakhe: Named for Áνδρομάχη, Andromakhe (‘battle of men’), a character in Greek mythology, she is the wife of Hector, Prince of Troy, and, in Homer’s epic poem Iliad, the mother of Ἀστυάναξ, Astyanax (‘city protector’).
Eponymy: Andromakhe (or Andromache) is a character in Greek mythology: the wife of Hector, Prince of Troy, and the mother of Astyanax. The name was chosen when the authors placed several species formerly in the genus Astyanax into this new genus. (Ref. 128868), visit book page.
