Abstract: Reconstructing the origin and historical
biogeography of the Austropotamobius torrentium is
hampered by insufcient phylogeographic coverage
of the Balkans and deep contradictions in previous
molecular dating. The present work extends the phylogeographic coverage to Serbia, a country crucial for
understanding the species southward dispersal. Our
analysis revealed that the Southern Balkans lineage
occurs in most of the country, the Central and southeastern Europe lineage is restricted to the southwest
and northeast of the country, while a single population in the north of the country harbors the Lika and
Dalmatia lineage, which was previously thought to be
restricted to the northern-central Dinarides. Dataset
expansion led to revised phylogenetic relationships,
which indicated that the Apuseni lineage is not nested
within Northern-central Dinarides lineages but arose
after the most basal split within Austropotamobius
torrentium. This ‘Apuseni frst’ phylogeny provides
a new perspective for molecular dating, according to
which the split between Austropotamobius pallipes
and A. torrentium took place in the Late Oligocene,
while the formation of the phyletic lineages and the
dispersal from the Dinarides to Serbia occurred in
the late Miocene and is probably associated with the
complex and protracted process of disintegration of
the Neogene freshwater lakes in southeastern Europe.
