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).

Short description
Morfología | Morfometría
This species can be distinguished from its known congeners by the following set of characters: gill pouches 8 pairs; 3-cusp multicusps on the anterior sets and 2-cusp multicusps on the posterior sets of cusps; total cusps 47-51; prebranchial pores 13-15; trunk pores 49-55; total pores 84-88; a single nasal-sinus papilla in the middorsal surface of the nasal sinus (Ref. 95645).
The holotype was collected from the type locality over green muddy bottom at bottom temperature of 6.8°C, surface water temperature 28.3°C (Anonymous, 1910). Additional specimens from the Verde Island Passage were collected at 578 and 710 m, sediment type ranged from mud to sand (Ref. 95645).
