The exotic snail Rumina decollata (Linnaeus, 1758) (Gastropoda, Achatinidae, Rumininae) in Argentina: new records, range extension, and areas of origin of Argentine populations.
The decollate land snail Rumina decollata (Linnaeus, 1758), which is native to the Mediterranean region, has been introduced to several countries worldwide. We report here three new records of R. decollata in Argentina: two from Córdoba Province and the first one from Misiones Province, which also constitutes the northernmost record for the country and extends its northeastern geographic range. Species-specific identification was achieved based on anatomical, conchological, and molecular information. DNA data showed that different haplotypes are present in Argentina, which originated from distinct source areas within the native range.
