Diagnostic Description

Differs from other Atlantic Canthigaster species by the long anterior extension of the lower horizontal dark stripe on the flank (composed of irregular horizontal and diagonal bars and originating as a solid stripe on the ventral caudal fin margin). This stripe reaches the pectoral fin base. Differs from C. jamestyleri by the presence of a dark caudal-fin margin, the absence of vertically oriented bars on the caudal fin, the possession of fewer stripes and spots on body especially on the dorsum, as well as by the absence of a small black irregular spot on the anal fin base (Ref. 43205).
