A new genus, Tologuica, with two species (T. aurorae sp. nov. and T. karhui sp. nov.), from the Middle Miocene of the Sharga locality (western Mongolia) is described. The new genus shares some characters with the extinct genera Palaeocryptonyx, Palaeortyx, and Plioperdix and with extant Coturnix. The foot structure suggests that Tologuica resembled in ecology the European genus Palaeortyx and was probably adapted to an arboreal mode of life, in contrast to the terrestrial Coturnix and Plioperdix.

The phasianid genera Perdix, Plioperdix, and Bantamyx from the Neogene of Mongolia and Transbaikalia are reviewed. Based on published data and new material, the diagnoses of Late Pliocene Perdix margaritae Kurochkin and Plioperdix ponticus (Tugarinov) and Late Miocene Bantamyx georgicus Kurochkin are emended. It is shown that a tarsometatarsus from the Upper Miocene of the Pavlodar locality belongs to the genus Palaeoperdix rather than Palaeortyx, as was proposed in the previous studies. Small Neogene Asian phasianids are compared in detail with Neogene taxa from Europe and extant genera.

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.
