La superfamilia Helicoidea (Pulmonata, Stylommatophora) en la provincia de Huesca

Abstract

The Helicoidea superfamily (Pulmonata, Stylommatophora) in the province of Huesca
From new and bibliographical records, 35 species of Helicoidea from the Huesca province have been listed and classified in six faunistical groups with different distnbutional pattems. Trochoidea elegans and Iberus gualtieranus are recorded for the first time for the province. An affinity analysis canied out using the Jaccard index shows four biogeographical sectors: West Pyrenees, East Pyrenees, Subpyrenees and the Ebro basin. Thesk sectors are well correlated with data from a previous phytogeographical analysis.
