ABSTRACT. Temnothorax mongolicus (Pisarski, 1969), previously known from the type localities in Zabaikalskii Krai, Amurskaya Oblast and Primorskii Krai, is registered from Olkhon Island in Irkutskaya Oblast of Russia for the first time. Multivariate analysis of morphometric data confirmed that newly found specimens from the Irkutskaya Oblast are conspecific with the type specimens of T. mongolicus (Pisarski). Specimens from the new locality are compared with the specimens from the Zabaikalskii Krai. Ecological characteristics and biotopic distribution of the species are provided.
