Saproxylic beetles of conservation interest in the Calabrian side of the Pollino National Park (Calabria, Italia): Lucanus tetraodon Thunberg, 1806, Osmoderma italicum Sparacio, 2000, Cerambyx cerdo Linnaeus, 1758 and Rosalia alpina (Linnaeus, 1758) (Coleoptera Lucanidae Cetoniidae Cerambycidae)

In this article an update on the distribution of Coleoptera Lucanus tetraodon Thunberg, 1806 (Lucanidae), Osmoderma italicum Sparacio, 2000 (Cetoniidae), Cerambyx cerdo Linnaeus, 1758 and Rosalia alpina (Linnaeus, 1758) (Cerambycidae) in the Calabrian side of the Pollino National Park is described. Data regarding the ecological part and the conservation status will be presented for each species. Therefore, of particular interest it can be noted: the presence in nine locations of L. tetraodon, an uncommon species and with little-known distribution; the discreet diffusion of O. italicum, rare and with a very restricted area, found in thirteen locations up to over 1800 m of altitude; C. cerdo for the Calabrian side of the National Park of Pollino; the first data for the presence of R. alpina at 1900 m altitude, the highest recorded in Italy and the discovery of larval stages on Italian alder (Alnus cordata), never ascertained in Italy. The Pollino National Park is confirmed as one of the areas of greatest national importance for the conservation of these xylophagous species linked to old forests.
