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).
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.
