J.: First occurrence ofRosalia longicorn Rosalia alpina (Linnaeus, 1758) in the valley of the Drava River (Hungary). Abstract: One male of Rosalia longicom Rosalia alpina (Linnaeus, 1758) was found on the shore of the Old- Drava side arm near Bares on the 1st July 2016. This was the first finding of this rare, Natura 2000 species in the area of the Drava valley which belongs to the Danube-Drava National Park. Keywords: distribution, long-horn beetles, Natura 2000, saproxilic species, Somogy Introduction Rosalia longicom Rosalia alpina (Linnaeus, 1758) is a saproxilic beetle species which is endangered and strictly protected through its range (Cizek et al. 2009) and it is also listed among species of special interest for the European ecological network Natura 2000 (European Commission 1992). This species lives in the forests of the mountains and hilly regions in Hungary. It occurs in the beech zone in the North Hungarian Mountains (Északi-középhegység) and Transdanubian Mts. (Dunántúli-középhegység), Mecsek Mts, Transdanubian Hills (Dunántúli-dombság) as well as in the Villány Hills (Hegyessy & Merkl 2014, Gy. Dudás pers. comm.). This species was not registered during the previous studies of long-horn beetles along the Drava River (Horvatovich 1995, 1998). Rosalia longicorn was not found either on the Croatian side of the Drava River (Katusic et al. 2017). Material and methods The natural values in the Old-Drava, side arm of the Drava River near Barcs, Somogy County (XL89 - according 10x10 km UTM), belonging to Danube-Drava National Park were investigated between 2015 and 2017. During intensive field work, special attention was paid to revealing Natura 2000 species and forest habitats (91E0 - Alluvial forests ISSN 1587-1908 (Print); ISSN 2062-9990 (Online)
