The Orthalicoidea are a superfamily of air-breathing land snails, terrestrial gastropod mollusks in the infraorder Orthalicoidei of the suborder Helicina [2]

Distribution

The Orthalicoidea is a dominant faunal element in the Neotropics, but also has a number of genera with a Gondwanan distribution. [1]

Taxonomy

2005 taxonomy

This taxonomy, as accepted by Bouchet & Rocroi, was based on the study by Nordsieck, published in 1986, [3] and the classification as formulated by Schileyko in 1999. [4] However Bouchet & Rocroi diverged from this classification in uniting the families Bulimulidae and Orthalacidae. They also considered the family Placostylidae as a distinct family from Orthalicidae, and the family Coelociontidae a distinct family from Urocoptidae. However, the position of the families Megaspiridae and Grangerellidae is doubtful. [5]

The following seven families have been recognized in the taxonomy of Bouchet & Rocroi (2005):

2008 taxonomy

Uit de Weerd moved two families Urocoptidae and Cerionidae to newly established superfamily Urocoptoidea based on molecular phylogeny research in 2008. [6]

2009 taxonomy

Family Prestonellidae van Bruggen, 1978 - A study by Herbert and Mitchell, published in 2009, places this enigmatic family, of which the phylogenetic relationships were previously unknown, in the Gondwanan superfamily Orthalicoidea, [7] while it was previously tentatively placed as a synonym of Aillyidae. [5]

2010 taxonomy

Breure et al. (2010) [8] moved Prestonella and Bothriembryon to Placostylidae and they elevated Bulimulinae to Bulimulidae, Odontostomini to Odontostomidae, Amphibuliminae to Amphibulimidae. [8] They also removed Coelociontidae from Orthalicoidea. [8]

2012 taxonomy

Breure & Romero (2012) [9] confirmed previous results from 2010, additionally they elevated Simpulopsini to Simpulopsidae, renamed Placostylidae to Bothriembryontidae. [9] Therefore, there are recognized seven extant [9] families and one extinct [5] family within Orthalicoidea:
