Chicoreus boucheti is the only species to which this new species may be compared, and even though the large and paucispiral protoconch, attesting of an intracapsular development, is the same, the teleoconch morphology is sufficiently distinct to separate both species. Found at the same depth and having the same distribution area, C. boucheti is more spinose and larger, the suture of the whorls is appressed, the spiral sculpture is more irregular and delicate. The aperture of C. boucheti has a broader columellar lip, a slighter
erect outer lip with the sculpture of the inner side being weaker and more irregular.
