The family Pleurodontidae includes some American taxa that used to be included within the Australasian family Camaenidae, a taxon whose monophyly was in doubt.
Anatomy
Pleurodontids are defined by a missing diverticulum. However the diverticulum is partially present in the genus Solaropsis. The stimulatory organ is equally missing. However, Solaropsis has in part a penial stimulator and a divided penis retractor muscle.
Genera
Genera within this family include:
Coloniconcha Pilsbry, 1933 - with the only species Coloniconcha prima Pilsbry, 1933[3]
Dentellaria Schumacher, 1817 - either separate genus (with a synonym: Lucerna)[4] or as a synonym of Pleurodonte[5]
