A new species of Calliotropis is described from the vicinities of the Concepcion Methane Seep Area (similar to 36 degrees S) and from additional material from off Antofagasta (northern Chile, similar to 22 degrees S). It is compared to C. pelseneeri pelseneeri Cernohorsky, 1977, and C. pelseneeri rossiana Dell, 1990, from the adjacent Antarctic area, which differ notably from the new species by having a thicker supra-peripheral spiral cord, more angulate whorls, and a more lamellose sculpture present in the subspecies pelseneeri. The new species is also separated from the widespread C. infundibulum (Watson, 1879) by having a weaker P1 spiral cord and narrower umbilicus with spiral cords inside. The radula of the new species is also typically calliotropine.
