Genus Pseudomonticlarella Smirnova, 1987

Type species. Pseudomonticlarella varia Smirnova, 1987

Diagnosis. Small, equibiconvex, striate, somewhat ligate; outline variable from rounded-triangular to rounded or pyriform; maximum width at midvalve; 3 to 5 lateral folds or plicae; anterior commissure with lateral folds resembling Monticlarella ; ventral sulcus broadly arcuate with trapezoidal linguiform extension; ventral umbo long with pointed and slightly incurved beak; foramen small, hypothyrid. Hinge teeth long, deeply inserted; dental plates subparallel to weakly ventrally divergent; strong socket ridges; elongated hinge plates supported by strong, low septum. From Manceñido et al. 2002, p. 1314.

Discussion. This diagnosis is for the genus established by monotypy. Therefore, it is also the diagnosis for the type species, Pseudomonticlarella varia Smirnova. It does not require emendation in the light of the new Spitsbergen material.

Occurrence. Upper Volgian–Lower (?Upper) Ryazanian.
