Taxonomy/Identity: First described from the upper Cenomanian of Algeria by Peybernès et al. (1988) having been first identified as a new taxon by Peybernès et al. (1984; see also Peybernès et al., 1986), this species differs from the more commonly recorded Aptian-Albian species P. cuvillieri Deloffre, 1961 , and the more recently described Barremian? – Aptian P. minima Schlagintweit et al., 2020 , in having a larger test (up to 16 mm diameter in microspheric forms) and a more discoidal rather than reniform test shape. Schlagintweit et al. (2020) provides useful comparative data.

It superficially resembles other thin, discoidal generic forms discussed herein such as Cyclolina , Cyclopsinella , Mangashtia and Dicyclina but differs in possessing a (small) post-embryonic peneropliform stage and a “… Choffatelliform hypodermis with polygonal subepidermal network ” ( Peybernès et al. (1988, p. 458 translated from original).

Confident Stratigraphic Range: not applicable.

Uncertain Stratigraphic Range: late Cenomanian.

Although described as occurring in the late Cenomanian in the only detailed report of this species ( Peybernès et al., 1988), this age assignment is based on co-occurrence with Pseudorhapydionina dubia ( De Castro, 1965) . Simmons & Bidgood (2023) noted that P. dubia has a long range within the Cenomanian, at least as old as middle Cenomanian, if not older.

Geographic Distribution: This species has so far only been reported from Algeria.
