Diversity[1] | |
1243 species (including Simpulopsidae and Bothriembryon). |
Distribution of species in the family Bulimulidae includes Ecuador (9 genera)[3] and other South American countries. Some species also occur in North America.
The family's oldest fossil record dates from the late Cretaceous of Brazil (Itaboraí Basin).[4][5]
Members of this family have a haploid chromosome number between 26 and 30 (according to the values in this table).[6]
Shells of species within Bostrycinae have a smooth protoconch and the genital organs feature a relatively long penis sheath (ca. 1/4–1/6 total phallus length).[7]
Previously, the members of the Orthalicidae were also included in this family, as the subfamily Orthalicinae, and the taxa listed here were placed in their own subfamily, the Bulimulinae.[8]
Bulimulinae was placed in the family Orthalicidae according to the taxonomy of the Gastropoda (Bouchet & Rocroi, 2005).[9]
The subfamily Bulimulinae included 3 tribes:[9]
Breure et al. (2010)[1] moved Bothriembryon to Placostylidae (since 2012 as Bothriembryontidae), elevated Bulimulinae to Bulimulidae and Odontostomini to Odontostomidae.[1]
Breure & Romero (2012)[10] confirmed previous results from 2010, additionally they elevated Simpulopsini to Simpulopsidae.[10] There are three subfamilies within Bulimulidae:[10]
