Bothriembryon Explained

Bothriembryon is a genus of tropical air-breathing land snails, terrestrial pulmonate gastropod mollusks in the family Bothriembryontidae.

B. J. Smith (1992) made the last review of the genus summarizing all known data.

Distribution

The land snail genus Bothriembryon is endemic to Australia but forms part of the Gondwanan element in the superfamily Orthalicoidea. Bothriembryon species are mostly patchy in their distribution.

Fossils of Bothriembryon have been found on the Nullarbor Plain in southern Australia, dating to the late Pliocene.^[1]

Taxonomy

This genus was classified with the Bulimulidae by Pilsbry (1900),^[2] Breure (1979)^[3] and by B. J. Smith (1992).^[4]

It was classified in tribe Bulimulini, in subfamily Bulimulinae within the family Orthalicidae according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005.

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

Breure & Romero (2012) confirmed previous results from 2010 and they renamed Placostylidae to Bothriembryontidae.^[6]
