Remarks

This small species is widely distributed around the island of Boa Vista. It is very variable, and it has given rise to the introduction of several names (applied to representative specimens from certain local populations from the southwest and south coasts of the island), which are hereby considered junior synonyms. In the molecular tree, it appears as sister to A. diminutus , with a short genetic distance. Both species belong to a clade in which all the individuals have medium-sized and very broad radular teeth. The specimens in the type series of A. barrosensis and A. varandinhensis exhibit shell coloration, pattern and shape consistent with the morphological variability of A. boavistensi s.
