Abstract

ARAIZA, Victoria  and  NARANJO-GARCIA, Edna. Systematic checklist of the terrestrial malacofauna from Atoyac, Veracruz. Rev. Mex. Biodiv. [online]. 2013, vol.84, n.3, pp.765-773. ISSN 2007-8706.  https://doi.org/10.7550/rmb.33106.

Previous studies about the gastropod diversity of Atoyac, demonstrated the presence of 37 terrestrial gastropods species. However, due to the disappearance of the natural landscape due to the increase in recent years of coffee and cane crops in the municipality and the lack in Mexico of specimens reported in those studies, it is interesting to document the actual diversity of the municipality, using collecting techniques directed to the study of the terrestrial malacofauna, so 21 localities were visited in Atoyac, Veracruz in 2007 and 2008. Fifty seven species, 21 subspecies and 19 families of terrestrial gastropods were found. The families with the largest number of species are Spiraxidae (with 17 species), Subulinidae (11), Euconulidae (8), Helicinidae (7) and Orthalicidae (6). The species with the widest distributions are: Hawaiia minuscula minuscula, Helicina (Tristamia) zephyrina zephyrina, Schasicheila (Atoyac) alata and Leptopeas micra. The malacofauna known in Atoyac increases in 21 species, 10 subspecies and 7 families; 5 species Pyrgodomus simpsoni, Pupisoma dioscoricola, Salasiella camerata, Pseudosubulina minuta and Punctum minutissimum are registered for the first time for Veracruz and 7 are possible new species.
