Type locality: localities in Poland, Latvia and Russia. Synonymy with G. catocala by Thomas (1987) . Notes. Although we have not studied the lectotype of Lophyrus catocalus , the interpretation of its taxonomic status is possible after referring to Gussakovskij's description of G. verticalis and the other publications cited above. We agree with Pschorn-Walcher (1982) and Viitasaari and Varama (1987) that the two forms are an expression of individual variability, linked to population differences with a geographical component. Accordingly, we treat Gilpinia catocala as a junior synonym of G. pallida .
