Distribution of Tree frogs (Hyla spp.) in Serbia: Implications of the recent taxonomic revision

We present the updated distribution data of the Hyla arborea species complex in Serbia. Hyla arborea inhabits all biogeographic regions, while Hyla orientalis inhabits only the easternmost parts of northeastern , Eastern and southeastern Serbia. Potential hybrid zone encompasses parts of central and southern Serbia from the Đerdap gorge, over Niš to Bosilegrad. Since the taxonomic separation UROŠEVIĆ, A. ET AL.: DISTRIBUTION OF TREE FROGS (HYLA SPP.) IN Serbia 138 between the tree frog taxa was not yet recognized in national nomenclature, we propose the official Serbian names. The species H. arborea will keep the standard Serbian name "Gatalinka", while for the species H. orientalis we propose the name "Istočna gatalinka".
