Etymology: Canthigaster: Greek, kanthos = the outer or inner corner of the eye, where the lids meet, 1646 + Greek, gaster = stomach (Ref. 45335); figueiredoi: Named in honor of José Lima de Figueiredo, for his contributions to the advancement of the taxonomy of Brazilian marine fishes, as well as for his long term encouragement and support to the authors (Ref. 43205)

Spine dorsali (totale): 0; Raggi dorsali molli (totale): 9-10; Spine anali 0; Raggi anali molli: 9. 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).
Inhabits coral-rich as well as coral-poor areas, and areas with rocky bottoms (Ref. 43205). Often in pairs, hovering over the reef during the day (Ref. 43205). Feeds on vegetation, sponges, crustaceans, and mollusks (Ref. 42064).
