Bioacoustics of Anterastes serbicus

Remarks. This species is found in the Balkan Peninsula and the Euro-Siberian phytogeographical region of Turkey , particularly along the Black Sea (Karadeniz) Region, which is home to many European-origin Orthoptera species. Some examples include Mechostethus thalassinus, Pholidoptera fallax , Ph. griseoaptera , Euthystira brachyptera , and Chorthippus macrocerus . Heller (1988: 120) conducted an acoustic study of this species in Greece and at two locations in northern Turkey : Ilgaz Mountain and Giresun , which is the type locality for A. boreoanatoliensis . He categorized all these populations as a single species. Additionally, there have been numerous records of A. serbicus from various locations along the Black Sea Region of Turkey , including the type locality of this new species, as documented by Karabağ (1958) and Ünal (2006, 2012, 2018), as well as Mol et al . (2016) . However, Uluar et al . (2023) , in their description of a new species, did not consider these earlier findings (refer to the remarks sections regarding Bolua and Anterastes ). The morphological characteristics, distribution, and song patterns suggest they belong to a single species; this contradicts the molecular findings of Uluar et al . (2023) . In molecular studies, it is known that genetic differences within the same species tend to increase with geographical distance. Therefore, if there is a continuous distribution within a species, the terminal populations should not be classified as different species if they still show the same morphology and acoustic characters. Thus, all previous distributional data are important and should be carefully evaluated when describing a new taxon. In the present study, the author compared several specimens of A. serbicus from Montenegro with a substantial collection that includes the topotypes of A. boreoanatoliensis housed in AİBÜEM, as well as published data. It is proposed that Anterastes boreoanatoliensis be considered a synonym of A. serbicus (see the Remarks section of Anterastes above).
