Carei Plain is a Protected Area in Northwestern Romania with a rich biodiversity, which among other human impacts, is threatened by road traffic. The road mortality intensity and its consequences were indicated in the region by some studies. During such a road mortality survey, realised in 2016, we identified five road-killed individuals of Carabus hungaricus, a rare species in Romania. Carei Plain is situated a few kilometres away from the area where the species presence was known in Hungary. The road is surrounded with sand dunes and wet areas with rich herbaceous vegetation, but also with Robinia pseudoacacia plantations. Carabus hungaricus is a rare species, with zoogeographic and conservation importance, affected by the road mortality in the region. The real distribution of C. hungaricus in the region should be established by investigating its potential habitats in the Protected Area.
