CORREA-SANDOVAL, Alfonso et al. Diversity and Zoogeography of terrestrial mollusks in Sierra of Tamaulipas, Mexico. Acta Zool. Mex [online]. 2017, vol.33, n.1, pp.76-88. ISSN 2448-8445.

Diversity and biogeography of Mexican terrestrial gastropods is poorly known. The terrestrial mollusks of the Sierra of Tamaulipas were surveyed from October 1988 to November 2005. A total of 482 samples were obtained from 30 localities, characterized with different vegetation types. Thirty-one genera and 46 species belonging to 18 families are recorded. The primary zoogeographical relationships are characterized by the presence of neotropical and neartic affinities (17 species: 37%) and the endemic taxa (11 species: 24%). The family Spiraxidae has the largest number of endemic species (6). The biogeographical value in this area is 3.78.
