Abstract

CASTILLO-RODRIGUEZ, Zoila G.; NARANJO-GARCIA, Edna  and  AMEZCUA-LINARES, Felipe. A new record of Huttonella bicolor (Hutton, 1834) (Mollusca, Gastropoda, Streptaxidae) in Mexico. Acta Zool. Mex [online]. 2018, vol.34, e3411181. ISSN 2448-8445.  https://doi.org/10.21829/azm.2018.3411181.

A specimen of Huttonella bicolor = Gulella bicolor (Hutton, 1834) was collected from clayey-sandy soil in Tabasco, Mexico, which constitutes its second record in the state and the third in Mexico. This small gastropod is a predator that has mainly spread through tropical and island regions as an exotic species. Its introduction to Asian and Caribbean Islands is noteworthy. Its pupiform shell and the lamella or tooth complex were compared against previous descriptions. In Mexico, this species has been found in northern Veracruz and Tabasco, which confirms that it is spreading along the Gulf of Mexico from the United States towards Brazil. The features of this streptaxid as a potential hazard through its preferred prey are discussed.

Keywords : Exotic species; land snail; Gulella; Tabasco.
