Here is an undescribed species from Coral Sea, Osprey Reef of the Great Barrier Reef of Australia. P. mccoskeri (bottom) for comparison is shown.
It was photographed by a Japanese diver there and he informed me that it formed a harem with a male and several females. The male was some 10 cm long, and is very similar to P. mccoskeri from the Indian Ocean. The coloration of the anal fin is quite outstanding and the filament on dorsal fin is robust. No specimen is available so no examination by ichthyologists. It is hard to say that it is a variant of mccoskeri for its remote locality, but it seems so close to that species.
