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]
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:
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:
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 in the family Spiraxidae include:
Subfamily Spiraxinae include seven[1] genera:
Subfamily Euglandininae
