Placostylidae Pilsbry, 1946

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

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 within the family Bothriembryontidae include:

Bothriembryontinae

Placostylinae

Prestonellinae
