(5) Physocypria ivanae (Díaz & Lopretto, 2011) comb. nov.

Following the synonymy of Keysercypria with Cypria and Physocypria (see below under New Synonymies for details), Keysercypria ivanae Díaz & Lopretto, 2011 is here provisionally transferred to Physocypria . However, the original description indicates that this species has tubercles on both valves, so its generic position needs to be revised.
