A single specimen of Lixus vilis (Rossi, 1790) was found during an examination of samples from a wildfire area in the Valais above Leuk. Very recently, further specimens of the species were additionally collected by one of the co-authors in the Central Valais. This large weevil lives on Erodium cicutarium (Geraniaceae) and was reported for the last time in Switzerland in 1906. Until now, this species has been without a reference specimen.
