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.

subfamily Bothriembryontinae Iredale, 1937 subfamily Placostylinae Pilsbry, 1946 - for species from New Zealand and Melanesia

Prestonellinae was formally described as a new subfamily within Bothriembryontidae in 2016.Bruggen A. C. van, Herbert D. G. & Breure A. S. H. (2016). "Prestonellinae – validation of the name as a new subfamily of Bothriembryontidae (Mollusca, Gastropoda, Orthalicoidea)". Zootaxa 4084: 590–592. Therefore three subfamilies are recognized in Bothriembryontidae: subfamily Bothriembryontinae Iredale, 1937 subfamily Placostylinae Pilsbry, 1946 Prestonellinae van Bruggen, Herbert & Breure, 2016
