'''''Austrolycus''''' is a genus of marine [ray-finned fish](/source/ray-finned_fish)es belonging to the [family](/source/Family_(taxonomy)) [Zoarcidae](/source/Zoarcidae), the [eelpout](/source/eelpout)s. The two species in this genus are found in the southeastern Pacific Ocean and the western South Atlantic Ocean off southern South America and the [Falkland Islands](/source/Falkland_Islands).

==Taxonomy==
''Austrolycus'' was first proposed as a [monospecific genus](/source/monospecific_genus) by the English zoologist Charles Tate Regan in 1913 when he [described](/source/Species_description) ''Austrolycus depressiceps'', giving the [type locality](/source/type_locality_(biology)) as the [Magellan Strait](/source/Magellan_Strait). Later, ''Lycodes laticinctus'', which had been described by Carlos Berg in 1895 from mouth of the [Rio Santa Cruz](/source/Santa_Cruz_River_(Argentina)) in Argentina, was placed within ''Austrolycus''.<ref name = CofF/><ref name = CofF2>{{Cof genus|genus=Austrolycus|access-date=16 October 2022}}</ref> This genus is classified within the [subfamily](/source/subfamily) [Lycodinae](/source/Lycodinae), one of 4 subfamilies in the family Zoarcidae, the eelpouts.<ref name = A&F2004>{{cite journal | author1 = Anderson , M.

==Etymology==
''Austrolycus'' is a compound of ''austro'' meaning "south" and ''lykos'', meaning "wolf"in [Greek](/source/Greek_language). the root of the [type genus](/source/type_genus) of the Lycodinae, ''[Lyciodes](/source/Lyciodes)''.<ref name = ETYFish>{{cite web | url = https://etyfish.org/perciformes14/ | title = Order Perciformes Suborder Cottoidea: Infraorder Zoarcales: Family: Zoarcidae | work = The ETYFish Project Fish Name Etymology Database | editor1= Christopher Scharpf | editor2 = Kenneth J. Lazara | name-list-style = amp |date = 6 May 2022 | access-date = 16 October 2022 | publisher = Christopher Scharpf and Kenneth J. Lazara}}</ref>

==Characteristics==
''Austrolycus'' eelpouts have [pelvic fin](/source/pelvic_fin)s and they have 6 [branchiostegal rays](/source/branchiostegal_rays). The gill slit does not extend down as far as the lower rays of the pectoral fins. There are between 27 and 33 vertebrae before the [caudal fin](/source/caudal_fin). They do not have a pyloric caecum. There are 6 or 7 pores below the eye and a single one behind the eye above the gill slit. The lack of a whitish strip on snout and head distinguishes these species from ''[Phucocoetes latitans](/source/Phucocoetes_latitans)''. In ''A. depressiceps'' the pelvic fins do not extend as far as, or just reach a vertical line through the base of the [pectoral fin](/source/pectoral_fin) base and there are between 72 and 79 caudal vertrebrae. In ''A. laticinctus'' the   pelvic fins clearly extend beyond a vertical line through the base of the pectoral fin and there are 80-89 caudal vertebrae.<ref name = A&G1991>{{cite journal | author1 = M.

==Distribution and habitat==
''Austrolycus'' eelpouts are found around southern South America. '' depressiceps'' is found in the southeastern Pacific Ocean from [Chiloé Island](/source/Chilo%C3%A9_Island) south to [Tierra del Fuego](/source/Tierra_del_Fuego) and it also occurs in the South Atlantic at the Falkland Islands,<ref name = Fishbase2>{{FishBase|Austrolycus|depressifrons|month=June|year=2022}}</ref> while ''A. laticinctus'' is found in the southwestern Atlantic in Argentina from [Puerto Deseado](/source/Puerto_Deseado) south to Tierra del Fuego.<ref name = Fishbase3>{{FishBase|Austrolycus|laticinctus|month=June|year=2022}}</ref> These demersal fishes are found in rocky areas in estuaries and in well vegetated areas of the [intertidal zone](/source/intertidal_zone).<ref name = Fishbase/><ref name = Fishbase3/>
