Taxonomy edit
2005 taxonomy edit
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 edit
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]
Genera edit
Genera in the family Spiraxidae include:
Subfamily Spiraxinae include seven[1] genera:
- Mayaxis Thompson, 1995[1]

- Pseudosubulina Strebel & Pfeffer, 1882[1]
- Rectaxis Baker, 1926[1]
- Spiraxis C. B. Adams, 1850[1] - type genus of family Spiraxidae
- Volutaxis Strebel & Pfeffer, 1882[1]
Subfamily Euglandininae
- Euglandina Crosse & P. Fischer, 1870 - type genus of the subfamily Euglandininae[2]
- Guillarmodia H. B. Baker, 1941[4]
- Pittieria von Martens, 1901[4]
- Poiretia Fischer, 1883[3]

Ecology edit
These land snails are carnivorous and predatory.[1]
