Pseudotriacanthus

Pseudotriacanthus is a monospecific genus of marine ray-finned fish belonging to the family Triacanthidae, the triplespines or tripodfishes. The only species in this genus is Pseudotriacanthus strigilifer, the longspined tripodfish. This taxon is found in the Indo-West Pacific region.

==Taxonomy== Pseudotriacanthus was first proposed as a monotypic genus in 1941 by the British ichthyologist Alec Fraser-Brunner with Triacanthus strigilifer designated as its type species. T. strigilifer was first formally described in 1849 by the Danish physician and biologist Theodore Cantor, with its type locality given as the Sea of Penang off Peninsular Malaysia. In 1843, Henri Hollard described this species as Monacanthus longirostris, predating Cantor's name, but this name fell into disuse and is a nomen oblitum. In 1968, James C. Tyler classified the family Triacanthidae within the suborder Triacanthoidei alongside the Triacanthodidae. The fifth edition of Fishes of the World classifies the Triacanthoidei as a suborder of the order Tetraodontiformes.
