Cryptophyllus sp. P1

(Pl. II: Fig. 12)

2013 Cryptophyllus sp. P1; Maillet: 98, pl. XII, fig. 2.

Material. 11 specimens (3 C, 7 V, 1 F).

Description. Medium-sized carapace, sub-triangular in lateral view. Moult retention ostracod with at least 6 exuviae. Large exuviae, slender posteriorly. Straight dorsal margin. Rounded umbo prominent over dorsal margin at 2/5 posterior. Anterior cardinal angle of about 150°. Posterior one of about 130°. Free margins of the carapace describing a regular bow. Anterior and posterior margins flattened. Anterior part of the carapace slightly wider and higher than posterior one. Hmax at 2/5 posterior; Lmax almost median; Wmax clearly dorsal and slightly posterior (umbo). Overlap of the valves unknown. Surface smooth.

Discussion. This morphology is similar to C. sp. C of Maillet (2013) from the Givetian of the Ardenne.

Occurrence. Middle Givetian (Candás Fm, mbs A and B), Asturias (Peran-Perlora section).
