This genus has high spired shells. The sculpture consists of spiral ribs, which are crossed by axial growth lines. At their crossing points scales are developed. The umbilicus is deep and rather narrow. Aperture rounded. Apart from the type species, also Calliotropis clavata (Watson, 1879) from the Caribbean belongs to this genus.

Genus Spinicalliotropis Poppe, Tagaro & Dekker, 2006
Type species: Spinicalliotropis spinosa (Poppe, Tagaro & Dekker, 2006) (by o. d.) - Recent, Philippines, Mindoro Island, MUSORSTOM 3, stn DR 94, 13°47fN, 120°04,N, 842 m. Gender: feminine.
Diagnosis. The main general conchological features of the Spinicalliotropis species are a rather small size (H<7 mm), a conical shape with convex whorls, spiral cords with spiny or scaly beads at their intersections with the axial threads, an almost circular aperture, a convex base with granular to prickly spiral cords, a moderately large umbilicus.
Remarks. This genus was originally proposed as a subgenus of Calliotropis, based mainly to spiny or scaly beads of the spiral cords (Poppe et ah, 2006). Spinicalliotropis was erected as a full genus based on anatomical characters, different from those of Calliotropis species (Kano et al., 2009).
