Taxonomy

This family has been named Placostylidae and had no subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).[4]

Breure et al. (2010)[5] moved Prestonella and Bothriembryon to Placostylidae.

Breure & Romero (2012)[2] confirmed previous results from 2010 and they renamed Placostylidae to Bothriembryontidae.[2]

  • subfamily Bothriembryontinae Iredale, 1937
  • subfamily Placostylinae Pilsbry, 1946 - for species from New Zealand and Melanesia[2]

Prestonellinae was formally described as a new subfamily within Bothriembryontidae in 2016.[6] Therefore three subfamilies are recognized in Bothriembryontidae:

  • subfamily Bothriembryontinae Iredale, 1937
  • subfamily Placostylinae Pilsbry, 1946
  • Prestonellinae van Bruggen, Herbert & Breure, 2016[6]
