2013 Fellerites sp. P1; Maillet: 66, pl. VII, fig. 9.

Material. 3 specimens (1 C, 2 V).

Description. Medium-sized equivalve carapace, truncated circular outline in lateral view, flat and slightly biconvex in dorsal view, almost symmetrical both, in lateral and dorsal views. Hmax median; Lmax at 2/5 dorsal; Wmax slightly dorsal. Straight hinge line and dorsal margin. Posterior cardinal angle of about 120°. Anterior cardinal angle of about 135°. From there, regularly convex free margins, describing a perfect circle. Carapace flattened around the cardinal angles. Surface punctuated.

Discussion. These specimens may belong to F. crumena (Kummerow, 1953), however, none of them is complete and surface is punctuate, not smooth.

Occurrence. Middle Givetian (Candás Fm, mb B), Asturias (Peran-Perlora section).
