Orthurethra

Orthurethra is a clade of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the clade Stylommatophora.

In the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005, Orthurethra is treated as an informal group and subclade of Stylommatophora.

In the revised taxonomy of 2017 this taxon is no longer supported and has been replaced by the infraorder Pupilloidei.
