The genus comprises three species which are found in the western central Pacific, southeastern Pacific and Southern Oceans.

==Taxonomy== ''Dieidolycus'' was first proposed as a monospecific genus in 1988 by the South Africa based American ichthyologist M. Eric Anderson when he described its type species ''Dieidolycus leptodermatus'', with its type locality given as south of South Georgia in the Scotia Sea at 55°01'-10'S, 39°55'-46'W, and from a depth of {{cvt|2886|-|3040|m}}.<ref name = CofF/.<ref name = CofF2>{{Cof genus|genus=Dieidolycus|access-date=28 October 2022}}</ref> This genus is classified within the subfamily Lycodinae, one of 4 subfamilies in the family Zoarcidae, the eelpouts.<ref name = A&F2004>{{cite journal | author1 = Anderson, M.

==Species== ''Dieidolycus'' has three species:<ref name = Fishbase>{{FishBase genus|genus=Dieidolycus|month=June|year=2022}}</ref> {{Linked species list | Dieidolycus adocetus | Anderson, 1994 | Dieidolycus gosztonyii | Anderson & Pequeño, 1998 | Dieidolycus leptodermatus | Anderson, 1988 }}

==Characteristics== ''Deiedolycus'' eelpouts have robust bodies which have a depth that is roughly 10% of their standard length. The skin is gelatinous and transparent and the muscles, bones and fin rays are clearly visible through the skin. They have no scales or lateral lines, although the sensory pores on the head are enlarged. The gills slit reaches vertically to the middle of the base of the pectoral fin.<ref name = FofSO/> The only measurement published is of ''D. leptodermatus'' which gives its maximum total length of {{cvt|16.6|cm}}.<ref name = Fishbase/>

==Distribution and habitat== ''Deiedolycus'' eelpouts are bathydemersal fishes found in the Pacific Ocean. ''D. leptodermatus'' Is found in the Southern Ocean, ''D. gosztonyii'' is found in the southeastern Pacific off Chile and ''D. adocetus'' in the Bismarck Sea.<ref name = Fishbase/>
