Goniistius is a subgenus of marine ray-finned fishes, traditionally classified as being within the genus Cheilodactylus and belonging to the family Cheilodactylidae, known as morwongs, although this name is not unique to this family and the true taxonomic placement of this taxon requires clarification. They are found in the Pacific Ocean and southeastern Indian Ocean.
Goniistius was created as a subgenus of Cheilodactylus in 1862 by the American ichthyologist Theodore Nicholas Gill with Cheilodactylus zonatus designated as its type species. [1] The name of the subgenus is a compound of gonio meaning “angle” and istios which means “sail”, Gill did not explain what his name alluded to but he may have been referring to the deep incision between spiny and soft-rayed parts of the dorsal fin of the type species. [2]
Genetic and morphological analyses of the family Cheolodactylidae have found that the family as traditionally arranged is polyphyletic. These analyses suggest that the a monophyletic Cheilodactylidae would contain only two species, the southern African C. fasciatus and C. pixi . Goniistius is then proposed to be a valid genus and would be placed in the family Latridae. [3] [4] [5]
The following species belong in this subgenus: [4] [5]
Goniistius is characterised by having an oval, compressed body. The mouth has thick, fleshy lips, In most species there is a bony processes on the frontal bone in line with the centre of the eye or it is in the front of the mouth in two species while in G. rubrolabiatus and G. zonatus it is absent. All species have a steep dorsal profile to the head and a deep body, other than G. rubrolabiatus There are 14-17 spines and 29-35 soft rays in the dorsal fin while the anal fin contains 3 spines and 8-12 soft rays, There are 14 pectoral fin rays, of these the lowermost 6 are simple and robust, and the fin does not extend to the anal fin. The pattern of the body is typically that there are a number of black and white diagonal bars along the body and head, except for G. rubrolabiatus, in which the black is replaced by reddish brown, and in G. zonatus in which yellow replaces the black. [4] The maximum total length of the species within Goniistius ranges from 22.1 cm (8.7 in) in G. zebra and 45 cm (18 in) in G. zonatus. [6]
The species in Goniistius are mainly found in the Pacific Ocean in both the northern Pacific and southern Pacific. [4] This genus contains the only morwongs found in the northern hemisphere. [7] Two species reach the eastern Indian Ocean. [6] They are found in rocky areas. [4]
Goniistius morwongs feed on benthic invertebrates which they pick from the substrate. [4]
Cheilodactylidae, commonly called morwongs but also known as butterfish, fingerfins, jackassfish, sea carp, snappers, and moki, is a family of marine ray-finned fish. They are found in subtropical oceans in the Southern Hemisphere. The common name "morwong" is also used as a name for several unrelated fish found in Australian waters, such as the painted sweetlips. The classification of the species within the Cheilodactylidae and the related Latridae is unclear.
The red moki also known as the banded morwong, brown-banded morwong, carp or nanua is a species of marine ray-finned fish, traditionally regarded as belonging to the family Cheilodactylidae, commonly referred to as morwongs. It is found off southern Australia and the North Island of New Zealand
The porae, the grey morwong, blue morwong, butterfish, Douglas' morwong, Eastern blue morwong, great perch, queen snapper, rubberlip morwong or silver morwong, is a species of marine ray-finned fish, traditionally regarded as belonging to the family Cheilodactylidae, the members of which are commonly known as morwongs. It is found around south eastern Australia and the north eastern coast of the North Island of New Zealand at depths of about 10 to 100 metres, on sandy and rocky coasts.
Nemadactylus macropterus, the tarakihi, jackass morwong or deep sea perch, is a species of marine ray-finned fish, traditionally regarded as belonging to the family Cheilodactylidae, the members of which are commonly known as morwongs. It is found in the south western Pacific Ocean, in Australia and New Zealand. Although there are records from the southern Indian Ocean and southwestern Atlantic, these may be due to misidentifications of similar species.

The magpie perch, magpie morwong or black-striped morwong, is a species of marine ray-finned fish, traditionally regarded as belonging to the family Cheilodactylidae, the members of which are commonly known as morwongs. It is found off southern Australia and northern New Zealand from shallow depths to 250 m (820 ft).
The barred fingerfin is a species of marine ray-finned fish, belonging to the family Cheilodactylidae, commonly referred to as morwongs. It is found only in the southeastern Atlantic and southwestern Indian Oceans off the coasts of South Africa.
The red morwong, also known as the sea carp, is a species of marine ray finned fish traditionally regarded as belonging to the family Cheilodactylidae, the members of which are commonly known as morwongs. It is found off southeast Australia and the North Island of New Zealand from shallow depths to at least 55 m, on rocky reef and coastal areas. Its length is between 30 and 60 cm.

They were formerly included in the genus Cheilodactylus in family Cheilodactylidae, but based on genetic and morphological analyses they have strongly suggested that the genus Morwong is a valid genus and should be placed in the family Latridae.
