Stabilisation of some names of European butterflies (Lepidoptera: Pieridae) in their prevailing usage

To stabilise nomenclature in its prevailing usage, the authors designate three lectotypes, respectively for the nominal taxa Pontia daplidice race nitida Verity, 1908 (Museo di Storia naturale della Universita di Firenze, sezione di Zoologia, 'La Specola' MZUF), for Euchloe crameri Butler, 1869 (Natural History Museum UK, NHMUK) and for Euchloe ausonia var. esperi Kirby, 1871 (National Museum of Ireland, NMI). They also designate two neotypes, respectively for [Papilio] ausonia Hubner, [1804] (MZUF) and for Pontia simplonia Freyer, 1829 (Jura Museum, Eichstatt, JME).
