Type locality: Azores, Atlantic Ocean. Bathypterois dubius , Quéro & Ribes, 1999 : 200 –204 (synonymized B. mediterraneus with B. dubius ); Bathypterois mediterraneus Bauchot, 1962: 639 , Figs. 4b, 6. Type locality: Rosas, Costa Brava, Spain . Bathypterois mediterraneus, Klausewitz, 1989 : 255 ; Galil & Goren, 1994 : 48; Goren & Galil, 1997 : 201; 2002: 151; Gates et al . , 2012 : 217–219 . Distribution. Northeastern Atlantic, Mediterranean; depth range 260–2800 m . Comment. Quero & Ribes (1999) , who compared the populations of B. mediterraneus and B . dubius from the northeast Atlantic and Mediterranean, concluded that they are identical and B. mediterraneus is a junior synonym of B. dubius . Froese & Pauly (2014) stated that B. mediterraneus "may be valid". Further taxonomic study using molecular tools may resolve the issue.
