The South Australian cobbler (Gymnapistes marmoratus), better known as the soldier but also known as the cobbler, devilfish or soldierfish, is a species of marine ray-finned fish, a waspfish, belonging to the subfamily Tetraroginae which is classified within the family Scorpaenidae, the scorpionfishes and their relatives. It is endemic to southern Australia. It is the only species in the monotypic genus Gymnapistes. Taxonomy The South Australian cobbler was first formally described in 1829 as Apistus marmoratus by the French zoologist Georges Cuvier with the type locality given as "Timor Island, southern Malay Archipelago", although this is likely to be an error and the actual locality is in Western Australia. In 1839 the English zoologist William John Swainson placed it in the new genus Gymnapistes, as its only species. This taxon is included in the subfamily Tetraroginae within the Scorpaenidae in the 5th edition of Fishes of the World however other authorities place that subfamily within the stonefish family Synanceiidae, while other authorities classify this subfamily as a family in its own right. The genus name is a compound of gymnos which means "bare" or "naked" with Apistes, this was originally proposed as a subgenus of Apistus and the first part alludes to the mostly scaleless body of this taxon. The specific name marmoratus means "marbled" as in alcohol this fish has a marbled appearance. Description The South Australian cobbler has a long based dorsal fin which has 12 or 13 spines, each separated by an incision in the membrane between them, and between 7 and 10 soft rays, the spiny and soft-rayed parts are separated by an incision, with 3 spines and 4 to 6 soft rays in its anal fin. It eye does not bulge above the dorsal profile of the head, the intraorbital space is slightly concave and there are several obvious spines on the head. The lacrimal bone is mobile and has a sizeable, curved, erectile spine to its posterior and a smaller anterior spine. The only scales are on the lateral line. This fish has a mottled pattern made up of brown to dark brown blotches on the upper body fading to pale ventrally. These blotches are less obvious in the larger fish. There is an obvious dark blotch on the dorsal fin between the 4th and 7th spines. There is a dark, oblong spot near the base on the pectoral fin while the other fins
