Original description: Brevoort 1856, Perry Exped. v. 2 (fig. 4) from specimens collected at Okinawa, Ryukyu Is., Japan. Based on a drawing. Validated by Allen 1991. Later described as Prochilus polylepis, by Bleeker 1877 in Versl. Akad. Amsterdam (Ser. 2) v. 11 from specimens
collected at Amboina, in southeast New Guinea. Synonym of Amphiprion frenatus.

Word origin: Amphiprion is from the Greek roots amph, -I, -o, meaning Around, on both sides; double, and -prion which means a saw. The genus frenatus is from the Latin root fren, -a, -at, =um, meaning bridle, probably in reference to the single head stripe.
