Genus Euchloe Hübner, [1819]

Three, basically parapatric, species of ‘dappled whites’ (genus Euchloe ) are unanimously recognised to occur in Europe, viz. 1) the eastern dappled white, 2) the mountain dappled white, and 3) the western dappled white. By common consensus, the names [ Papilio ] ausonia (Hübner, [1804]) , Pontia simplonia Freyer, 1829 and Euchloe crameri Butler, 1869 , in the same order, have slowly become fixed to identify them ( Bernardi 1945, 1947, Tolman & Lewington 1997, Tshikolovets 2011, Wiemers et al. 2018, etc.).

Each of these names is riddled with interpretational and nomenclatural problems principally deriving from mismatches between characters shown by the illustrated type materials and their stated type localities. As required by Art. 75.3.1 ( ICZN 1999 and later updates), these problems will be resolved by designating two lectotypes and two neotypes.
