Stead (Ed. Fish. N.S. Wales) has expressed the opinion that 

 /'. nigromarginatus is merely the male form of P. gymnogenis 

 which attains a larger size than the female. In support of this it 

 must be noted that the distribution of the two is the same and 

 that both are obtained from the same localities, which are usually 

 in the vicinity of rocky reefs, etc. The more robust form of 

 P. nigromarginatus as compared with P. gymnogenis is only 

 what is found in all large specimens of Vseudolabrus, while the 

 colour differences between the two are not more striking than 

 what I have found between young and old examples of /'.
