Abstract
Two very rare boxfishes, Kentrocapros flarofasciatus and K.rosapinto, are redescribed on the basis of specimens collected from the western Pacific and south-western Indian Oceans.They are easily distinguished from the only other congener, K.aculeatus, by having no spines on the carapace.Kentrocapros flavofasciatus differs from K.rosapinto by the location of the gill opening: in the former the gill opening is below the posterior half of the eye, while in the latter it is restricted below the posterior edge of the eye.The monotypic genus Aracanostracion is regarded as a junior synonym of Kentrocapros on the basis of the comparisons of the external and osteological characters among these three species.
