The Orthalicoidea are a superfamily of air-breathing land snails and slugs, terrestrial gastropod mollusks in the informal group Sigmurethra.[1]
This taxonomy, as accepted by Bouchet & Rocroi, was based on the study by Nordsieck, published in 1986, [2] and the classification as formulated by Schileyko in 1999 [3]. 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.
Taxonomy
- Family Cerionidae Pilsbry, 1901
- Family Coelociontidae Iredale, 1937
- † Family Grangerellidae Russell, 1931
- Family Megaspiridae Pilsbry, 1904
- Family Orthalicidae Albers, 1860
- Family Placostylidae Pilsbry, 1946
- Family Urocoptidae Pilsbry, 1898 (1868)
- Family Prestonellidae van Bruggen, 1978 : A study by Herbert and Mitchell, published in 2008, places this enigmatic family, of which the phylogenetic relationships were previously unknown, in the Gondwanan superfamily Orthalicoidea [4], while it was previously tentatively placed in the superfamily Achatinoidea.
