Etymology: Eptatretus: hepta (Gr.), seven; tretos (Gr.), perforated (i.e., with holes), referring to seven gill apertures on what would later be described as Homea banksii (=E. cirrhatus) [range within genus is 6-14 pairs of gill apertures]. (See ETYFish);  luzonicus: -icus (Gr.), belonging to: Luzon Island, Philippines, type locality [replacement name of E. fernholmi McMillan & Wisner 2004, which became a junior homonym of Paramyxine fernholmi Kuo, Huang & Mok 1994 when Paramyxine was subsumed into Eptatretus]. (See ETYFish).
