The family Spiraxidae consists of the following subfamilies:
- Spiraxinae H. B. Baker, 1939
- Micromeninae Schileyko, 2000
2010 taxonomy
Thompson (2010) have redefined subfamilies in Spiraxidae and have moved Euglandininae and Streptostylinae as subfamilies of Spiraxidae. There are three subfamilies within Spiraxidae:- Spiraxinae H. B. Baker, 1939 - including Micromena
- Euglandininae H. B. Baker, 1941
- Streptostylinae H. B. Baker, 1941
Apparently, this is not universally accepted, as Fauna Europaea states another systematics for the Euglandininae subfamily, still placing it among the Oleacinidae family .
