Abstract

Stenogyropsis is one of the few genera of Helicoidea having a high-spired shell. Here, we describe a new species (Stenogyropsis chorismenostoma n. sp.) that has a further remarkable trait: its last quarter whorl is detached from the penultimate whorl. We also show that a partly detached last whorl has evolved much more frequently in terrestrial Caenogastropoda than in Stylommatophora relative to the number of species within those groups. This may be due to the more superficial contact of the neighbouring whorls in the former group.
