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.

Catalogue of ants of Europe, the Mediterranean Basin and adjacent
regions is given with country data, list of synonyms, and comments. From the area 1261
species are rocorded. All infraspecific names, including subspecies names, are treated as
synonyms although in future studies many of them can be raised to species level. Table with
distribution of ant species in major regions of Europe and the Mediterranean Subregion is
presented. From Europe 622 species have been recorded, from North Africa 441, Middle
East 256, Turkey and transcaucasian countries 358, Iran 165, and Arabian Peninsula 304.

The paper presents the first detailed research of the ants (Formicidae) of Plana Mountain
(Western Bulgaria). A total number of 49 species were identified, 44 of which are new the studied
area. Tetramorium hungaricum (R\öszler, 1935) and Formica exsecta Nylander, 1846, reported from Plana
by other authors, were not found during the current research. The paper also provides a brief
zoogeographical analysis of the local ant fauna and a comparison with those of the adjacent Vitosha
and Lozen Mountains. Some habitat information and additional remarks are given as well.
