Comment

Prior to the publication of Dufresnes, Strachinis, Tzoras, Litvinchuk, and Denoël, 2019, ZooKeys, 859: 131–158, the species was considered a race of Pelobates syriacus or not distinct from that species whatsoever (Eiselt, 1988 "1986", Ann. Naturhist. Mus. Wien, Ser. B, 90: 51-59). Szabolcs, Mizsei, Jablonski, Vági, Mester, Végvári, and Lengyel, 2017, Amphibia-Reptilia, 38: 435–448, provided a dot map and discussion of range in Albania (as Pelobates syriacus). Phylogeographic study of Pelobates provided the evidence whereby Dufresnes, Strachinis, Tzoras, Litvinchuk, and Denoël, 2019, ZooKeys, 859: 131–158, recognized this species. Dufresnes, Strachinis, Suriadna, Mykytynets, Cogǎlniceanu, Székely, Vukov, Arntzen, Wielstra, Lymberakis, Geffen, Gafny, Kumlutaş, Ilgaz, Candan, Mizsei, Szabolcs, Kolenda, Smirnov, Géniez, Lukanov, Crochet, Dubey, Perrin, Litvinchuk, and Denoël, 2019, Mol. Ecol., 28: 3257–3270, reported on the hybrid zone with Pelobates syriacus. See Dufresnes, 2019, Amph. Eur., N. Afr., & Middle East: 58, for brief summary of identifying morphology and biology, a range map, as well as a photograph. Koynova, Marinova, and Natchev, 2022, Herpetol. Notes, 15: 303–305, reported specimens from Vetrishte, Shumen Province, northeastern Bulgaria. Mollov, Natchev, Koynova, Kambourov, Rashkov, Dimitrov, Todorov, Petrova, Vladov, and Uzunov, 2022, Ecol. Balkanica, Spec. Edit. 5: 43–74, discussed the presence of this species (as Pelobates syriacus) in protected areas of southeastern Bulgaria.
