Abstract: A comparison of the zoogeographical peculiarities of the myrmecofauna in urban and non-urban habitats in Sofia region is performed. The proportion of the widespread Holarctic species was twice as high in the urban as compared to the non-urban sites. Also Euro-Caucasian elements are well represented in the urban sites. The share of South-Transpalaearctic, Eurasian steppe and Boreo-Montane elements is low or such elements are absent from the urban sites.
