摘要

Rabaulichthys squirei is described as a new species of the serranid subfamily Anthiinae from 12 specimens collected at Flinders Reef and Flora Reef in the Coral Sea from 6 to 54 m. A huge population was also observed at Holmes Reef in 55 m. The species is distinct from three others of the genus by the combination of a high count of 23 or 24 lower-limb gill rakers, relatively long snout, a very high spinous portion of the dorsal fin of the male, and subtle differences in colouration. It forms small elusive aggregations that feed on zooplankton, mainly over open substrata of coral rubble.
