Cataegis new genus, type species C. toreuta new species, is proposed to include three new species from continental slope depths (200-2,000 m): the type species and C. meroglypta from the Gulf of Mexico to Colombia, and C. celebesensis from Makassar Straits, Indonesia. Important shell characters are the prominent spiral cords, non-umbilicate base, and oblique aperture. The radula is unique among the Trochidae in lacking the rachidian, having the first pair of laterals fused and uncusped, and the first marginals enlarged. The gill is the advanced trochid type with well-developed afferent membrane. These characters do not correspond to an available subfamily; the new subfamily Cataeginae is therefore proposed.
