Erratum to A third European species of grayling (Actinopterygii, Salmonidae), endemic to the Loire River basin (France), Thymallus ligericus n. sp., published in Cybium 2019, 43 (3)

In the paper, the description and the diagnosis of Thymallus ligericus n. sp. Persat, Weiss, Froufe, Secci-Petretto and Denys, 2019, a mistake was done with a permutation between 'concave' and 'convex' concerning the snout profile. Moreover, one paratype have an occipital depth of head of 60.9% HL (instead of 54.8% HL). So the values for this character in the table i are 66.6 (60.9-71.7). In consequence, we correct here these points.
