Bothriembryontidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Orthalicoidea.

Taxonomy

This family has been named Placostylidae and had no subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005). Breure et al. (2010) moved Prestonella and Bothriembryon to Placostylidae. Breure & Romero (2012) confirmed previous results from 2010 and they renamed Placostylidae to Bothriembryontidae. Prestonellinae was formally described as a new subfamily within Bothriembryontidae in 2016. Therefore three subfamilies are recognized in Bothriembryontidae:

Genera

Genera within the family Bothriembryontidae include: Bothriembryontinae Placostylinae Prestonellinae A cladogram based on nuclear ITS2, 28S rRNA and histone 3 (H3) and sequences of mitochondrial cytochrome-c oxidase I (COI) genes showing phylogenic relations of Bothriembryontidae by Breure & Romero (2012):

Distribution

Bothriembryontidae have Gondwanan distribution.
