Material. 2 carapaces from Mitsero (MAB13996, holotype and MAB13531, paratype)

Locality and stratigraphy. Mitsero; Koronia Member (Pakhna Formation, late Serravallian-early Messinian).

Etymology. The species is named after Mitsero, the locality where the holotype and paratype were found.

Description. The shape of the carapace of P. mitseroensis sp. nov. is subcircular, of which the anterior part is circular in outline, the posterior is square, with rounded corners. There are no teeth on the keeled anterolateral margins, a short, downturned rostrum, a bilobed frontal with small orbital ridges on the onset of the rostrum. The epibranchial region is faintly bulbous and well defined. The cervical groove is well defined, the branchial groove is less defined and disappears laterally. The gastric region is well defined and shows a deep dent posteriorly of the mesogastric region.

The surface is smooth, with exception of the branchial region near the posterolateral margin, which is striated.

Remarks. This species can be distinguished from its congeners in having a subcircular carapace, striations on the metabranchial region, a short, downturned rostrum, a faintly bulbous epibranchial region and in lacking anterolateral teeth.
