A new species, Bilacunaria aksekiensis A. Duran & B. Doan (Apiaceae), is described and illustrated from Anatolia, Turkey. It grows in open Pinus brutia forests and on calcareous stony slopes of the Taurus Mountains in the district of Akseki (C3 Antalya province). Bilacunaria aksekiensis is morphologically close to B. microcarpa. The diagnostic morphological characters of B. aksekiensis are discussed. In addition, the pollen characteristics and mericarp surface of B. aksekiensis and B. microcarpa are examined by SEM. The geographical distribution of the new species and the morphologically related species is mapped. Bilacunaria aksekiensis is diploid with the chromosome number of 22.
