Simone, Luiz Ricardo L., 2006, Morphological and phylogenetic study of the Western Atlantic Crepidula plana complex (Caenogastropoda, Calyptraeidae), with description of three new species from Brazil, Zootaxa 1112 (1), pp. 1-64 : 30-31

Crepidula fornicata (Linné, 1758)

(Fig. 114)

Synonymy see Simone (2002: 38). Complement:

Crepidula fornicata: Collin 1995: 815–829 (fig. 1); 2001 (fig. 4); Simone 2002: 38–40 (figs. 10, 11, 71, 72, 160–164).

The anatomical description provided by Simone (2002) is appropriate. The single addition is the female genital papilla. This structure is broader than those of remaining species; a pair of broad, longitudinal folds running in posterior side close from each other, with a shallow and narrow furrow between both, both finishing at some distance from genital pore (Fig. 114). Another longitudinal fold running in right side, narrow, slightly sinuous, starting gradually in base of papilla, finishing also gradually far from pore. Genital pore with thick edges, marked by deep, radial furrows.

Additional material examined. UNITED STATES OF AMERICA; Florida; St. Petersberg , MZSP 35843 , 14♀ (T. Bert col. 1997, R. Collin leg. & id.) .

N.B.: The lot ANSP 411047 is 3 shells almost certainly of C. fornicata , however, the collect data is URUGUAY; Rocha, La Paloma 34º40S 54º09W (E. Duarte leg iii/1959). It is possible that some change of data happened and this species does not occur in the south Atlantic .
