In the system of modern Russian studies, a significant place is occupied by multidisciplinary, parallel, South Russian socioeconomic studies conducted in many regional centers, whose development in recent years has been accompanied by the circulation in scientific discourse of a wide range of heterogeneous, "different-time", sometimes inadequate geographical realities of toponyms and geoconcepts. The article focuses on the need for their ordering, as well as correction, including taking into account modern geopolitical determinants. Priority attention is paid to the presentation of modern South Russian and adjacent territories in numerous
historically successive zoning schemes (since the XIX century) and the potential of using the corresponding "archival" toponymy in regionalism. It is shown that post-Soviet spatial innovations not only generated and brought to the forefront the geoconcept "South of Russia", but also predetermined its subsequent homonymy. The geopolitical and ethnodemographic determinants of modern South Russian regionogenesis are analyzed. The necessity of additional inclusion in the updating geographical picture of the world of the extremely broad geoconcept "The Large South of Russia " in its meaningful sound is substantiated, its internal fragmentation,
the "migrating" nature of borders, conjugacy (including mutual incorporation) with other macroformats of spatial structuring of Eurasia is revealed.
