More than 20 species were reported under the circum Black Sea lineage Poecilimon bosphoricus group (Orthoptera, Tettigonioidea, Phaneropterinae). The taxonomy of the group has for a long time been controversial; once these species were transferred to Eupoecilimon and many new species have been described since the revision by Ramme (1933) or synonyms have been suggested/re-established. This study aims to test the classification of the group presently based on morphological characters by bioacoustic data. The following results were obtained or conclusions arrived. First, several qualitative morphological characters previously used in descriptions/diagnoses of the species are variable and overlap between species. Those are the elevation and widening of pronotum in metazona, the emargination of caudal margin of pronotal disc and the structure of male subgenital plate at caudal margin. Thus, still the male cercus, especially the orientation of denticles, is the most productive structure may allow more objective delimitation of species. As in qualitative morphology the general morphometry seems uninformative for the taxonomy of the group. Second, male calling song and partly the number of stridulatory pegs are more useful characters both for delimitation of species and describing their relationships. Especially, the pattern of the syllable, the number of impulses per syllable and the duration of early part of syllable in species group allow us a more objective delimitation of the species and definition of relationships. Third, from the distribution and relationships of species, we suggested three radiation centres for the lineage: (1) Northwest Anatolia + Eastern Balkans, (2) Northeast Anatolia + Caucasus and (3) Crimea. Fourth, after evaluating morphological and song phenotypes we considered 21 species in P. bosphoricus group constituting three subgroups: (1) P. sureyanus and P. kocaki (+ P. athos), 2) P. turcicus + P. turciae and (3) P. bidens, P. bischoffi, P. bosphoricus, P. cervus, P. demirsoyi, P. geoktschajcus, P. heinrichi, P. istanbul, P. miramae, P. pliginskii, P. proximus, P. roseoviridis sp. n., P. scythicus, P. similis and P. tauricus (+ P. djakonovi). The following nomenclatural actions were made: (1) P. roseoviridis Chobanov & Kaya sp. n. described, (2) P. similis proximus Unal, 2010 raised to species level as P. proximus stat. n., (3) P. naskrecki Unal, 2001 syn. n. synonymised with P. demirsoyi Sevgili, 2001 (4) P. diversus Unal, 2010 syn. n. and P. anatolicus Ramme 1933 syn. n. put in synonymy with P. sureyanus Uvarov, 1930, (5) P. oligacanthus Miram, 1938 syn. n. and P. tereckensis Stshelkanovtzev, 1910 stat. rev. resynonymised with P. similis Retowski, 1889, (6) P. beybienkoi Tarbinsky, 1932 syn. n. and P. kusnezovi Miram, 1929 syn. n. synonymised with P. tauricus Retwoski, 1888, and (7) P. boldyrevi Miram, 1938 syn. n. synonymised with P. pliginskii Miram, 1929.
