Notes on the taxonomy of a forgotten tree snail: Drymaeus cuticula is a juvenile Cochlorina aurisleporis (Gastropoda: Bulimulidae)

We propose that Drymaeus cuticula (Pfeiffer, 1855) is a junior synonym of Cochlorina aurisleporis (Bruguière, 1792) based on an analysis of their conchological characters. Aside from appearing on a few species checklists, D. cuticula has been relegated to taxonomic oblivion for decades, likely due to new specimens being readily attributed to its more well-known synonym. By synonymising the two species, we clarify the status of D. cuticula and contribute to ongoing efforts to revise the taxonomy of the genus Drymaeus.
