Polyphylla ichnusae new species from Sardinia with notes on Mediterranean Polyphylla (Col. Scarabaeidae Melolonthinae Melolonthini) - G.Sabatinelli, M.T. Nuvoli & D.Cillo
Abstract. – Polyphylla ichnusae n. sp., a Sardinian endemic, was previously reported in Sardinia as P. fullo (Linnaeus, 1754). Distinctive male genitalia, bidentate protibiae and light-brown elytral integument indicate that P. i c h n u s a e represents an autochthonous species, clearly distinct from Corsican and continental populations of P.fullo. This finding further supports the higher level of endemism in Sardinia compared with Corsica. The new species appears to be restricted to north-eastern Sardinia, from sea level to approximately 1,000 m, where it inhabits mixed Pinus–Quercus forests. In comparing the new species with other Mediterranean Polyphylla, we also confirm the previously supposed conspecificity of P.algirana Brenske, 1896 and P. macrocera Reitter, 1891 with P.fullo (Linnaeus, 1758). A catalogue and a male identification key to Mediterranean Polyphylla species are provided with illustrations of the habitus, parameres and key characters (69 photos).
