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.

Harpagoxenus sublaevis (Nylander, 1849) was found among ants taken in pitfall traps set in the Alibotoush Reserve, Slavjanka Mountain in southwestern Bulgaria. This species is new to the Bulgarian myrmecofauna that recently numbered about 130 species.
