Bothriembryontidae


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.
Breure et al. moved Prestonella and Bothriembryon to Placostylidae.
Breure & Romero 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. Therefore three subfamilies are recognized in Bothriembryontidae:
  • subfamily Bothriembryontinae Iredale, 1937
  • subfamily Placostylinae Pilsbry, 1946
  • Prestonellinae van Bruggen, Herbert & Breure, 2016
