Rhinus suturalis ( Baker, 1914)

( Fig. 21 )

Bulimulus (Rhinus) rochai suturalis Baker, 1914:620 , 637 (pl. 23, figs. 13-14) [Mongúba, Ceará & Baturité R.R., ~ 27 km from Ceará]; Haas, 1939:269; Breure, 1979:131.

Rhinus rochai suturalis : Morretes, 1949:148; Dutra- -Clarke & Souza, 1991:291 (pl. 3, fig. 3) [Recife, PE].

Rhinus suturalis : Salgado & Coelho, 2003:163; Simone, 2006:129 (fig. 416).

Types: Holotype ANSP 109322a. Paratype FMNH 14099 (all examined).

Remarks: The shells collected in that Bahia region are conchologically indistinguishable from the type specimens of R. suturalis ( Simone, 2006, fig. 416), which so far was known to northern states Ceará and Pernambuco ( Baker, 1914; Dutra-Clarke & Souza, 1991). The present report expands the geographic distribution of the species towards the south and east about 800 km. B. suturalis belong to what can be called “complex Rhinus durus (Spix, 1827) ”, a group of species with obese, short shell which has a relative good anthropic acceptation, commonly found in home gardens and parks throughout Northeastern Brazil. Then, anthropic transportation cannot be completely disregarded.

Material examined: BRAZIL. Bahia; Santa Maria da Vitória , ~ 13°24’S, 44°12’W, ~ 460 m of elevation, MZSP 103924 , 4 shells (Coltro col., i/2012) .
