Before 2005, the snails in this genus were all thought to belong to one species, which was known as Crepidula aculeata, the spiny slipper snail.^[1] However, morphological and DNA sequence data show that the spiny slipper snails are a monophyletic group that is more closely related to Crepipatella than it is to Crepidula.

Taxonomy

Taxonomic history

All of the species within the genus Bostrycapulus were previously assigned to a single species, Crepidula aculeata.^[1] However, molecular phylogenetic and anatomical work have shown them to be a separate monophyletic grouping or clade, which has elevated them to the genus status.^[1] DNA sequence data has also been used in combination with embryological observations to distinguish 8 species.^[1]
