25. Chorthippus biguttulus (Linnaeus, 1758)

25.1. Chorthippus biguttulus biguttulus (Linnaeus, 1758) = širokokrili livadni skakavac

First faunistic record for Croatia: Graber 1870

Also reported as: Chorthippus variabilis Fieber, 1852 (Frauenfeld 1861), C. biguttulus hedickei (Ramme, 1942) (see Taxonomic note)

Distribution in Croatia: Nominal subspecies only. Widespread and common in all regions.

Distribution in Europe: Widespread, from the Pyrennees to the Urals and from Greece to Southern Scandinavia. In Italy occurs only north of the Po Valley (Hochkirch et al. 2016).

Taxonomic note: Populations from the Pannonian lowland and the Balkans were assigned to C. b. hedickei (e.g. Mikšić 1970, Helversen 1989). However, no morphological or bioacoustic differences that would evidence separation of more than one group within this species were found among Croatian populations (unpublished data).

Thus, we consider further investigations necessary to clear out the infraspecific taxonomy of this species.
