Family Camaenidae Pilsbry, 1895

Remarks.

Camaenidae and Bradybaenidae are traditionally distinguished on the basis of the absence of the dart sac and mucous glands in the former and the presence of these structures in the latter. The molecular phylogeny of Wade et al. (2007) showed that the dart sac was lost multiple times during the evolution of the Camaenidae . Camaenidae and Bradybaenidae form a single clade, and neither of them is mono phyletic. Therefore Gittenberger et al. (2012) formally treated the Bradybaenidae as a junior synonym of Camaenidae . Bouchet et al. (2017) retained the subfamily Bradybaeninae Pilsbry, 1934 under Camaenidae . This system is followed here.
