Urocoptidae Explained

Urocoptidae is a family of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the superfamily Urocoptoidea.

Taxonomy

2005 taxonomy

The family Urocoptidae was classified in the superfamily Orthalicoidea (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).

The family Urocoptidae consists of 7 subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005):

• Urocoptinae Pilsbry, 1898 (1868) - synonym: Cylindrellidae Tryon, 1868
• Apomatinae Paul, 1982
• Brachypodellinae H. B. Baker, 1956
• Eucalodiinae P. Fischer & Crosse, 1873
• Holospirinae Pilsbry, 1946
• Microceraminae Pilsbry, 1904 - synonyms: Johaniceraminae Jaume & de la Torre, 1972; Macroceraminae Jaume & de la Torre, 1972
• Tetrentodontinae Bartsch, 1943

2008 taxonomy

Uit de Weerd (2008) moved the Urocoptidae to the newly established superfamily Urocoptoidea based on molecular phylogeny research.^[1]

The following cladogram based on Bayesian analysis of sequences of 28S ribosomal RNA shows the phylogenic relations within the Urocoptoidea.^[1] There are up to 2008 genetically analyzed species of Urocoptidae and one species of Cerionidae marked in khaki color in the cladogram.^[1]

2012 taxonomy

Fred G. Thompson established the family Epirobiidae in 2012 for five genera of snails (Epirobia, Propilsbrya, Pectinistemma, Gyrocion, Prionoloplax), that were previously placed within Urocoptidae.^[2] Data from molecular phylogeny research as well as morphology supports monophyly of Holospiridae Pilsbry, 1946 and the Eucalodiidae Crosse & Fischer, 1868.^[2]
