Phylogenetic analysis based on osteological characters of some Neogene and Recent phasianids is performed. Phylogenetic tree shows close relationships of Plioperdix with Ammoperdix and Tologuica with Excalfactoria. Chauvireria is at the base of the clade (Alectoris + (Coturnix + (Excalfactoria + Tologuica))). Palaeoperdix is relatively close to the lineage of large pheasants.
