Spirlins of the southern Black Sea basin, with the description of a new species (Teleostei: Leuciscidae)

Abstract

Alburnoides turani, new species, from the Filyos River drainage is described and the distribution of the nine other Alburnoides species known from the southern Black Sea basin is revised. Alburnoides turani is distinguished by having a naked ventral keel, or the keel is covered with 1-3 scales between the posterior pelvic-fin base and the anus, an interoibital distance wider than the eye diameter and the snout length, 48-55 total lateral-line scales, 5-6 scale rows between the analfin origin and the lateral line, 131/2 -141/2 branched anal-fin rays, and 41-42 total vertebrae.
