Etymology: Trachonurus: Greek, trachon, -onos = roughness + Greek, oura = tail (Ref. 45335); robinsi: Named for C. Richard Robins.
Eponymy: Dr Charles Richard ‘Dick’ Robins (1928–2020) was an American systematic ichthyologist whom one etymology honoured as an ‘eelologist’; as well as a colleague, advisor and friend, for his contributions to the knowledge of fishes (including [...] (Ref. 128868), visit book page.
