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.
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).
The family Spiraxidae consists of the following subfamilies:
- Spiraxinae H. B. Baker, 1939
- Micromeninae Schileyko, 2000
Thompson (2010) 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.
Genera in the family Spiraxidae include:
Subfamily Spiraxinae include seven genera:
These land snails are carnivorous and predatory.
