An updated checklist of the scarab beetle fauna of Asinara Island, Sardinia, Italy (Coleoptera: Trogidae, Geotrupidae, Scarabaeidae, Aphodiidae, Cetoniidae, Dynastidae, Hybosoridae)

The island of Asinara, located in the northwest of Sardinia, is characterized by a large number of feral grazing mammals belonging to four herbivorous species (horse, donkey, mouflon, and goat) and an omnivorous one (wild boar). Hand-collections of scarabs in 2014 and the examination of unpublished records revealed the presence of five species new for Asinara (Trox nodulosus, Ateuchetus laticollis, Sisyphus schaefferi, Caccobius schreberi and Cetonia carthami). Based on all records (published and unpublished) we present a new checklist of the scarab beetle fauna of Asinara which increased from 30 to 43 species belonging to seven families: 2 Trogidae, 2 Geotrupidae, 13 Scarabaeidae, 19 Aphodiidae, 5 Cetoniidae, 1 Dynastidae, and 1 Hybosorida
