'''''Lindbergichthys''''' is a [[genus]] of marine [[ray-finned fish]]es belonging to the [[Family (taxonomy)|family]] [[Nototheniidae]], the notothens or cod icefishes.<ref name="WoRMS">Froese, R. and D.

They are native to the [[Southern Ocean]].

==Taxonomy== ''Lindbergichthys'' was first formally [[Species description|described]] in 1976 as ''Lindbergia'', a [[subgenus]] of ''[[Lepidonotothen]]'', by the [[Soviet]] [[ichthyologist]] [[Arkady Vladimirovich Balushkin]] with ''Notothenia mizops'' as the type species.<ref name = CofF/> However, [[Pristilomatidae|Lindbergia]] was preoccupied by a [[Gastropod]] genus described by [[Alexander Riedel|Riedel]] in 1959 and in 1979 Balushkin replaced the name with ''Lindbergichthys''.

==Etymology== The name of honours the Soviet ichthyologist [[Georgiĭ Ustinovich Lindberg]] who died in 1976.<ref name = Balushkin>{{cite journal | author = Balushkin, A.V. | year = 1979 | title = Lindbergichthys (Nototheniidae) — a new generic name for Lindbergia Balushkin, 1976 non Riedel, 1959 | journal = Voprosy Ikhtiologii | volume = 19 | issue = 5 | pages =930–931 | language = Russian}} English translation in Journal of Ichthyology v. 19 (no. 5):144-145</ref> The genus is not recognised by all authorities and, for example, is treated as a [[Synonym (taxonomy)|synonym]] of ''[[Nototheniops]]'' by the ''[[Catalog of Fishes]]''<ref name = CofF/> but is treated as a valid genus by [[FishBase]].<ref name = FishBase/> Some authorities place this taxon in the [[subfamily]] Nototheniinae,<ref name = Gon>{{cite book | editor1 = O.

==Species== Two recognized species are in this genus:<ref name=FishBase>{{FishBase genus|genus=Lindbergichthys|month=June|year=2021}}</ref> * ''[[Lindbergichthys mizops]]'' ([[Albert Günther|Günther]], 1880) (Toad notie) * ''[[Lindbergichthys nudifrons]]'' ([[Einar Lönnberg|Lönnberg]], 1905) (Yellowfin notie)

==Characteristics== ''Lindbergichthys notothens ''have a variable amount of scales on the head but the snout. lower jaw, nasal area, the area to the front of the eyes and the orbit are always unscaled. The rear part of the head may be scaled or unscaled. The upper lateral line has tubed scales while the middle [[lateral line]] has no tubed scales. In smaller fishes the pelvic fins are longer than the pectoral fins but they are equal in size in larger fishes. The [[caudal fin]]s have 12-14 branched fin rays.<ref name = Gon/> The maximum [[total length]] is between {{cvt|15|and |19.5|cm}}.<ref name = FishBase/>

==Distribution and habitat== ''Lindbergichthys'' notothens are found in the [[Scotia Arc]] from the [[Antarctic Peninsula]] to [[South Georgia]] in the Atlantic section of the [[Southern Ocean]] and from the [[Kerguelen Islands]], [[Heard Islands]], [[Crozet Islands]] and [[Prince Edward Islands]].<ref name = Gon/>

==Biology== ''Lindbergichthys'' notothens are benthic fishes which feed on small benthic invertebrates moving on to fish eggs and small crustaceans when they are larger.<ref name = Gon/>
