Aurila sp. 1

Fig. 7 :10–19

Material. 11 specimens (five from MP-612 and six from MP-747).

Figured specimens. CP-465 e CP-466 (carapaces); CP-467, CP-468, CP-469 and CP-470 (valves) ( Tab. 12).

Remarks. Generic diagnosis follows Pokorný (1955) and Jellinek (1995), except for the presence of an anterodorsal shoulder, resulting from the fusion of ribs close to the posterior cardinal angle. This characteristic is also present in Aurila n. sp. ( Bold 1975), and Aurila auricula Teeter, 1975 ( Teeter 1975; Bold 1988). Aurila . sp. 1 differs from these species by its smaller size and details in ornamentation.
