Species

Two recognized species are in this genus: * '' Lindbergichthys mizops'' ( Günther, 1880) (Toad notie) * '' Lindbergichthys nudifrons'' ( 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
