Spiraxidae is a family of predatory air-breathing land snails, terrestrial pulmonate gastropods in the superfamily Testacelloidea (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).
The distribution of this family is Neotropical.[1]
Taxonomy
2005 taxonomy
The family Spiraxidae is classified within the informal group Sigmurethra, itself belonging to the clade Stylommatophora within the clade Eupulmonata (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).[2]
The family Spiraxidae consists of the following subfamilies:
- Spiraxinae H. B. Baker, 1939
- Micromeninae Schileyko, 2000
2010 taxonomy
Thompson (2010)[1] redefined subfamilies in the Spiraxidae, moving Euglandininae and Streptostylinae to become subfamilies of Spiraxidae. According to their work, there are three subfamilies within the Spiraxidae:
- Spiraxinae H. B. Baker, 1939 - including Micromena
- Euglandininae H. B. Baker, 1941
- Streptostylinae H. B. Baker, 1941
Apparently this system of classification is not universally accepted, as Fauna Europaea uses different systematics for the subfamily Euglandininae, still placing it within the family Oleacinidae.[3]
