30. Chorthippus eisentrauti ( Ramme, 1931) = alpski livadni skakavac

First faunistic record for Croatia: Ebner 1951

Distribution in Croatia: Reported from NW Dinaric Alps (e.g. Ebner 1951, Nagy 2006). Male calling song from Učka Mt., Kapela Mt. and Velebit Mt. close to Senj is similar to that of typical C. eisentrauti (Skejo, unpublished

data). Thorough taxonomic and biogeographic study has not been carried out yet, but is necessary to determine whether this species is present in Croatia, or these are hybrid populations between C. eisentrauti and C. biguttulus . Distribution in Europe: Endemic to the southern and eastern parts of the Alps. It ranges from the Haute-Alpes, just at the border to Italy in the west, over Val d´Aosta, Tessin and Graubünden in Switzerland along the southern edge of the Italian Alps eastwards to Southern Austria Northern Slovenia. It is very similar to the closely related Chorthippus biguttulus , so the precise distribution is often unclear and misidentifications (and even hybrids) are not rare ( Zuna-Kratky et al. 2016).
