Type locality

Off Mobile Bay , Alabama .

Distribution

Northwestern Atlantic; Gulf of Mexico; Caribbean Sea ( McCain 1968; Oliva-Rivera 2003; Foster, Thomas, et al. 2004; Diaz et al. 2005; Ortiz and Lalana 2010).

Records in the Gulf of Mexico

MEX: Yalahau Lagoon ( Oliva-Rivera and Jiménez-Cueto 1997; present study); Campeche Sound ( Winfield et al. 2006); Celestun; Progreso; Dzilam Bravo; Rio Lagartos; El Cuyo; Cabo Catoche (present study). USA: Mississippi-Alabama continental shelf ( Mayer 1903); Strait of Florida ( Pearse 1908); between Delta of the Mississippi River and Cedar Key ( Pearse 1912); Alligator Harbor ( Steinberg and Dougherty 1957); Port Isabel; Puerto Aransas; Mobile Bay; Tampa Bay, Key Largo ( McCain 1968); St Andrew Bay; St Joseph Bay (Foster, Thomas, et al. 2004).

Habitat

Deutella incerta shows predatory habits to obtain its food; however, detritus is the dominant stomach content reported ( Caine 1974). This species is widely distributed in the temperate and tropical areas of the western North Atlantic ( McCain 1968), and has been collected on mangrove roots, Sargassum sp. , Thalassia sp. , sponges, hydroids, alcyonarians, ascidians, coral rubble, sandy bottom, detritus and it has occasionally been taken in plankton tows ( Guerra-García 2003b; Oliva-Rivera 2003; Diaz et al. 2005; Guerra- García, Krapp-Schickel, et al. 2006). The depth range reported is shallow water extending to 1470 m ( Winfield et al. 2006; Winfield and Escobar-Briones 2008; LeCroy et al. 2009).

Remarks

Steinberg and Dougherty (1957) synonymized the monotypic Luconacia of Mayer (1903) with Deutella , transferring L. incerta to Deutella . McCain (1968) re-established Luconacia and claimed several important differences between the genera. Finally Gable and Lazo-Wasem (1987) described a transitional species ( Deutella aspiducha Gable and Lazo-Wasem 1987 ) that allowed them to re-unite Deutella and Luconacia , which was later supported by Guerra-García (2003b).

McCain (1968) did not mention the record of D. incerta to Tampa Bay, although it is represented in his map. Thereby it is assumed to be a valid record.
