Messina Strait and Ustica Isola, in the southwestern Tyrrhenian Sea. The species has been discovered in the circalittoral, on bottoms colonized by the coral Errina aspera (Linnaeus, 1767), and also on kelp beds of Laminaria rodriguezii Bornet, 1888. Both environments are characterized by the presence of strong currents and low temperature (Giaccobe & Renda, 2019).
 
The shell of this species is compared to those of catenatus, montagui and tumidulus; it differs from catenatus by the general pattern, which is here yellowish brown with reddish spiral bands and mottled with white blurred blotches building like « irregular and interrupted axial stripes » (Smriglio & al., 2016); the shell of errinae differs from that of montagui by « the sculpture more tuberculate and densely ornamented with growth striae, producing a more jagged appearance of the shell surface, and the different shell chromatic pattern »; from tumidulus by its larger size in adults, a higher spire, and by the colour set. In fact, what mainly characterizes the shell of errinae is this red-brownish spiral banding on a yellowish bakground, with the whitish maculations.
