The status of golden loaches (genus Sabanejewia) in the region of Central
Europe and Balkans is still ambiguous. The greatest controversy is caused
by species Sabanejewia balcanica and S. bulgarica, whose distinguishing
features are often difficult to prove and their occurrence in some river
sections is often mentioned as sympatric. Previous phylogenetic studies
aimed at the resolving of their taxonomic status did not include samples
from their type localities and so led to a lack of their true distribution
in this region. Therefore, the main aim of this study was to identify the
taxonomic status of golden loaches populations in this area on the model
territory of Slovakia. For this purpose, we used a novelty approach
(morphological, molecular and microhabitat) and we also included the
missing samples from the type localities of both species. Based on mtDNA
all the Slovakian samples reflected haplotype richness revealed on the
type locality of S. bulgarica, although the genetic distances from other
representatives of the genus Sabanejewia occurring are not significant.
Within the morphology, we have revealed a great measure of variability in
studied populations, which is largely caused by different habitat
conditions and thus representing a phenotypic plasticity of these fish.
