摘要：

A new species of seven-gilled hagfish Eptatretus astrolabium (Myxinidae) is described from a 400 mm total length female trapped 1 km east from Planet Rock, Astrolabe Bay, Papua New Guinea, at c. 500 m depth. This is the first hagfish species reported from the waters around New Guinea. It can be distinguished from other hagfishes by a combination of characters including seven pairs of gill apertures, three-cusp multicusps on the anterior and posterior rows of cusps, 10 posterior unicusps, 52 total cusps, 18-19 prebranchial pores, five branchial pores, 48-49 trunk pores, 83-84 total pores and no nasal-sinus papillae.
