TABLE 2 in Rhizotrogus ruzzantei, a new species from southwestern Sardinia (Italy), with biogeographic considerations on the Sulcis-Iglesiente subregion and Scarabaeoidea endemics of Sardinia (Coleoptera: Scarabaeidae: Melolonthinae: Rhizotrogini)

TABLE 2. Results of PERMANOVA testing interspecific differences between Rhizotrogus genei Blanchard (n=28) and R. ruzzantei sp. nov. (n = 23) across eight morphological characters where df is the degrees of freedom, MS is the mean squares, F-ratio quantifies the strength of each effect.
