New data and distribution of common spadefoot toad Pelobates fuscus (Laurenti, 1768) (Anura: Pelobatidae) in Western Balkans

Based on known literature data and data collected during field research in 2014 and 2015, we present updated distribution map of the common spadefoot toad (Pelobates fuscus) in Western Balkans (Bosnia and Herzegovina and Croatia). Pelobates fuscus is listed as least concern on the global IUCN Red List, data deficient in Croatian Red Book and the populations are in constant decline. Until year 2014 this species was only suspected to inhabit Bosnia and Herzegovina. Today we have confirmed localities in Posavina region (western, central and eastern part) presented with precise coordinates and elevation. In this paper we also present first findings of tadpoles, more precisely, the reproductive sites of the common spadefoot toad in the Bosnia and Herzegovina. In Croatia, this species is found along the rivers Mura, Drava and Sava, including most lowland areas up to 300 m above sea level. Historical records of Pelobates fuscus in Adriatic region are discussed and compared with distribution area of Italian isolated population.
