This species differs from the true Polydactyly.* plebeius of Samoa in its much larger scales and also in its 

 different color, its less concave anal and -rend dorsal, its deeper body, and shorter, blunter snout. In 

 P. zophomus the free pectoral filaments reach but little beyond tip of pectoral, while in P. plebeius they reach 

 beyond tip of ventral.

P. zophomus has been confounded with Polydactylies plebeius, as the above synonymy indicates. It is, 

 however, quite distinct from the latter and equally so from the common Japanese species, Polydactylus ayonasi 

 Jordan & McGregor, which also has been recorded as Polydactylus plebeius.
