Material and measurements: Six complete carapaces in dorsal view ( MSF 1171 – lcxp: 9 mm, wcxp: 9 mm; MSF 2314 – lcxp: 15 mm, wcxp: 13 mm; MSF 2321 – lcxp: 6 mm, wcxp: 5 mm; MSF 2322 – lcxp: 8 mm, wcxp: 6 mm; MSF 2323 – lcxp: 14 mm, wcxp: 13 mm; MSF 2324 – lcxp: 10 mm, wcxp: 8 mm).

Discussion. The studied specimens are confidently as- signed to Palaeomyra bispinosa A. Milne Edwards in E. Sismonda, 1861 in having a globose subrounded carapace covered by irregular small tubercles; bilobate front; small rounded orbits; deep gastro branchial groove; suboval rounded cardiac region; and posterolateral corners with an elongate spine.

The species was described by A. Milne Edwards in E. Sismonda (1861) from the Miocene sandstone of the hills around Torino (Piedmont, NW Italy), and later reported from the Oligocene of Morbello , Alessandria, and the Miocene of Cocconato (Asti, Piedmont) by Garassino et al. (2004) .
