Santa Maria material examined. Maximum height 24.0 mm, width 15.0 mm. DBUA-F 869-2 (1), DBUA-F 867 (1), Ponta dos Cedros; DBUA-F 1295 -D (1), Malbusca (west cave); DBUA-F 161-10 (1), Pedreira do Campo; one specimen from LNEG collection (unnumbered), unknown locality, Santa Maria Island, Azores, Touril Complex, Lower Pliocene.
Description. Azorean material too incomplete for description. See Landau & Fehse (2004: 8).
Discussion. The best preserved specimen is an unnumbered complete adult in the LNEG collection, photographed by one of us (August 2012, SPA). Unfortunately, the specimen is slightly rotated on apertural view, and the photograph out of focus on dorsal view. On a subsequent visit to rephotograph the specimen it could no longer be found (May 2022, CS). The other Azorean specimens consist of fragments and internal moulds.
Schilderia flavicula (Lamarck, 1810) and Schilderia garonettii Fehse, 2004, have a more elongated shell. Zonaria porcellus (Brocchi, 1814) is much larger with a more produced anterior extremity. Schilderia utriculata is a typically Mediterranean Pliocene species that survived into the early Pleistocene before becoming extinct. This would be the first Atlantic record for the species.
Distribution. Lower Pliocene:?Atlantic, Santa Maria Island, Azores (this paper); central Mediterranean, Italy (Chirli 2008; Sosso & Dell’Angelo 2010). Upper Pliocene: western Mediterranean, Estepona Basin, Spain (Landau & Fehse 2004); central Mediterranean, Italy (Sacco 1894; Pavia & Demagistris 1970; Inzani 1985; Fehse 2001 c, 2004), Cyprus, Algeria (Inzani 1985). Lower Pleistocene: central Mediterranean, Italy (Cerulli-Irelli 1911; Malatesta 1960).
