Review of Indo-Pacific species of the scorpionfish genus Scorpaena (Teleostei: Scorpaenidae), with descriptions of two new species from the west coast of Australia

A taxonomic review of Indo-Pacific species of the scorpionfish genus Scorpaena resulted in the recognition of 21 valid species (including 2 subspecies and 2 new species) and 13 synonyms. The new species, Scorpaena longaecrista and Scorpaena sororreginae, were described on the basis of 50 and 23 specimens, respectively, from the west coast of Australia. Updated definitions of both the genus and species of Indo-Pacific Scorpaena, based on previously published characters and confirmed by examination of type and non-type specimens in this study, are provided. A diagnosis, synonymy, distribution, and list of specimens examined (or appropriate citation if previously published in detail) are given for each species, together with an identification key for all valid Indo-Pacific species of Scorpaena.
