4. Omocestus viridulus (Linnaeus, 1758)

A record of the species (Pongrácz 1944) from the surroundings of Kopački Rit is questionable, but impossible to review since the collection in Hungarian Natural History Museum was destroyed in 1956. We did not find the species as there are no suitable habitats in Croatia (Alpine meadows). Revised material (Croatian Natural History Museum, Faculty of Science in Zagreb) previously identified as O. viridulus turned out to be O. rufipes (in some cases green Chorthippus sp. or Stenobothrus sp.). Since no evidence exists confirming its presence in the country, we omit the species from the checklist.
