Abstract
    A taxonomic review of the genus Banjos (Perciformes: Banjosidae), previously restricted to a single species, Banjos banjos (Richardson 1846), recorded from the northwestern Pacific Ocean from the South China Sea north to Japan, as well as Lombok (Indonesia), New Caledonia and Australia, resulted in the recognition ofthree species, including B. banjos (northwestern PacificOcean, Indonesia and western Australia), Banjos aculeatus sp. nov. (eastern Australia) and Banjos Peregrinus sp. nov. [northern Australia (Timor Sea)]. Records of B. banjosfrom New Caledonia probably also represent B. aculeatus,which is clearly distinct from other congeners in having a relatively long, strongly serrated spine at the posteroventral angle of the preopercle and an entirely dusky membrane on the spinous dorsal fin in juveniles\ca. 70 mm SL, in addition to slightly longer first and second dorsal-fin spines. Banjos Peregrinus is characterized by a relatively greater head length, orbit diameter, postorbital length andpre-pelvic-fin length, as well as poorly developed serration of the exposed margin of the cleithrum. Within B. banjos, a population from the southeastern Indian Ocean, including Indonesia and western Australia, is regarded as a distinct subspecies (Banjos banjos brevispinis ssp. nov.), distinguishable from B. banjos from the northwestern Pacific Ocean by a relatively narrow least interorbital width, and shorter second and eighth dorsal-fin spines. Ontogenetic morphological changes within the genus and the status ofthe holotype of Anoplus banjos Richardson 1846 are discussed in detail.
