An invasive snail population of Xerolenta obvia was discovered at the end of 2021 in Sant Julià de Lòria (Principat d'Andorra). This location, the first occurrence of this species for this country, is intermediate between the few locations in the south of France and the only known location in Spain. For its taxonomical determination, morpho-anatomical studies of the shell and the reproductive system have been carried out, and it has been compared with other species of geomitrids that are more similar based on the shell, such as Cernuella neglecta or Helicella itala and even, for less expert people, with Xerosecta cespitum arigonis, also present in Andorra. X. obvia is an invasive species, considered as a pest, which can produce serious impacts on agriculture. From a parasitological-veterinary point of view, it acts as an intermediate host for helminths (nematodes, trematodes, cestodes) and various pathogenic fungi, and can affect animals and humans. Regarding its eradication and control, X. obvia has been an objective in several countries and a project is currently underway to eradicate it in the municipality of Linares de Mora by the Government of Aragon (Spain).
