Non-native terrestrial slugs from Sinaloa, Mexico: Deroceras laeve (O. F. Müller, 1774) and Sarasinula plebeia (P. Fischer, 1868) (Mollusca, Gastropoda)

Abstract

This is the first record of two non-native terrestrial slug species from Sinaloa, Mexico. Deroceras laeve and Sarasinula plebeia were collected between 2019 and 2022 in Concordia and Mazatlan Municipalities (north-western Mexico). The external morphology and anatomic features of the dissected specimens coincide with the descriptions of each species, whose identities were also confirmed by their partial COI sequences. The ample occurrence of S. plebeia suggests that this species has an established population, while D. laeve was found as isolated individuals, likely associated with plant nurseries.
