Catalogue of the ants (Hymenoptera, Formicidae) of Bulgaria Author Lapeva-Gjonova, Albena Author Antonova, Vera Author Radchenko, Alexander G.

(Peshtera) [ Atanassov 1936 (as Formica nasuta )]. Notes: Atanassov and Dlusskij (1992) noted that specimens determined by Forel (1892) and Atanassov (1964) as Proformica nasuta in fact are Proformica striaticeps (see below). At the same time, they stressed that material, based on which ( Atanassov (1934 , 1936 ) recorded Proformica nasuta for Bulgaria, has been lost, and it is impossible to make definitive conclusion on the taxonomic status of those ants. Proformica nasuta is definitely distributed in the Iberian Peninsula and France, but it is also recorded from Romania and Greece (see Marko et al. 2006 , Radchenko 2007 ). As we cannot exclude its occurrence in Bulgaria, we include this species in the current list; on the other hand, this data needs confirmation.
