The phylogenetic relationships and taxonomy of the spirlins in the genus Alburnoides are examined by 36 comparative sequencing analysis of mitochondrial and nuclear markers. Molecular analyses revealed 37 17 Eurasian lineages divided into two main clades, termed the Ponto-Caspian and European in accor- 38 dance with the lineage distribution. The indel diagnostics of b-actin and S7 markers and translation of 39 cyt b to the amino acid chain were evaluated as a reliable identifying tool for most of the recognised lin- 40 eages. Lineage richness is closely connected with the existence of known glacial refugia in most cases. The 41 underestimation of species richness in the genus Alburnoides is confirmed: the genetic analyses support 42 the validity of 11 morphologically accepted species; apart from them, four phylogenetic lineages requir- 43 ing descriptions as separate species were revealed. The distribution area of the nominotypical species A. 44 bipunctatus s. stricto is newly defined. Two diverging phylogenetic lineages, A. ohridanus, and A. prespensis 45 complex, were observed in the Southeast Adriatic Freshwater Ecoregion, confirmed as a hotspot of ende- 46 mic biodiversity. A. ohridanus demonstrates high divergence from the A. prespensis complex, represented 47 by three similar mitochondrial lineages with the same nuclear haplotypes and sympatric occurrence. The 48 range restricted endemism was confirmed for at least seven species. The Albanian river systems, as well 49 as the wider Ponto-Caspian basin exhibit complications among definite species delineations and gaps in 50 understanding of microevolutionary processes; these areas require further investigations.
