We give a list of 29 ant species in Vrachanska Planina Mountain from 24 localities. Nine species were confirmed by previously reported data. Among all 19 unpublished species (found in 50\’s of last century and during 2013-2014), 10 are new for the region. Four species are of nature conservation importance.

The myrmecofauna of the green areas in Sofia City was extensively sampled by qualitative and quantitative methods to assess spatial variation in species composition of ant assemblages. The cluster analysis of the assemblages based on presence/absence data resulted in grouping into two main clusters: woody and open habitats. The assemblages of the open areas further divided into two groups: grassy habitats and artificial biotopes (asphalt coverings and agricultural land). Most of the assemblages in open areas clearly demonstrated the impact of urbanization by grouping into three main zones depending on the distance from the city centre: central, peripheral and rural.

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.

Seven nests of coexisting ant species in the city of Sofia and its vicinity were discovered. Five of
these were reported from Zapaden park, one from Knyaz Borisova Gradina and one from Vladaja
village. Two of the nests represented mixed colonies probably with temporary parasitic interaction
between species of the genus Lasius. The compound nests included species from the genera Lasius,
Leptothorax, Myrmica and Formica. Solenopsis fugax was found in lestobiotic interaction with two species
of the genus Lasius within one of the mixed colonies.

The present catalogue of the ants (Hymenoptera, Formicidae) of Bulgaria is made on a base of critical
reconsideration of literature (covering the period from 1892 till 2009 and part of 2010) as well as on
examination of the authors\&$\#$39; and several museum\&$\#$39;s collections. A lot of data were omitted in the previous
Bulgarian monograph on ants, lots of new data were recently added and many important additions and
alterations were made due to taxonomic revisions of Eurasian Formicidae during the last three decades.
Two new species are reported for the country [Temnothorax graecus (Forel, 1911) and Temnothorax cf. korbi
(Emery, 1924)].
This catalogue contains a list of 163 ant species belonging to 40 genera of 6 subfamilies now known
from Bulgaria. Synonyms and information on the previously reported names in relevant publications are
given. Known localities of the species are grouped by geographic regions. Maps with concrete localities or
regions for each species were prepared. The conservation status of 13 ant species is given as they are includ-
ed in IUCN Red List of Threatened Species and Bulgarian Biodiversity Act. In comparison with adjacent
Balkan regions the ant fauna of Bulgaria is quite rich and its core is composed of South European elements.
