Previously considered the same as P. philippinus, but recently described as a different species. It has pale spots on each scale and all-black median fins, but best distinguished based on location. So far known only from eastern Australia. Records in the Coral Sea outside of the Great Barrier Reef may potentially be a different species, recently separated (P. nirgriradiatus).


Max Size: N/A cm

Sea Temperature Range: N/A

Depth: N/A

Habitat Generalization Index: 12.66

Also referred to as the SGI (Species Generalisation Index), this describes the habitat niche breadth of the species. Species with values less than 15 are found in a relatively narrow range of reef habitat types (specialists), while those over 25 may be found on most hard substrates within their range (generalists).

Conservation and Rarity

IUCN Status: Not Evaluated

Occurrence: Common (32.7% of sites)

Occurrence describes how often the species is found on surveys within its distribution. It is calculated as the % of reef sites surveyed by RLS divers across all the ecoregions in which the species has been observed

Abundance: Many (22 per transect)

Abundance is calculated as the average number of individuals recorded per RLS transect, where present.
