Abstract
The review includes the comparative analyses of Plebejus christophi (Staudinger, 1874), P. argivus (Staudinger, 1886), P. argivus noah (Herz, 1900), comb. nova et stat. novus, and P. roxane (Grum- Grshimailo, 1887). Three new taxa are described: P. karinae sp. nova (NW Kazakhstan, Atyrau reg., NW Kulsary town), P. paveli sp. nova (E Kazakhstan, south of Lake Zaisan, Zhagalbaily Mts.) and P. argivus kazakh ssp. nova (Kazakhstan, Transili Alatau Mts., northern foothills). The distinctions of the genitalia are discussed in details. Some notes about P. bergi Kuznetzov, 1908 are added, including designation of the neotype.
