Interchangeable taxa

As a smooth species, C. albertoi resembles C. rustica, C. gerhardtae De Jong & Coomans, 1988 (see Rolan & Crúz-Abrego, 1998: 6, fig. 15) and C. aulakion. Caelatura albertoi has a stronger varix than that of C aulakion, and a granulose texture on the protoconch, whereas it is smooth in the latter species. Also, C. aulakion has a peripheral furrow between the body whorl and the base, whereas C. albertoi has no such furrow. Caelatura albertoi can be distinguished from C. rustica and C. gerhardtae by the lack of a varix behind the aperture in the two latter species.
