Alburnoides manyasensis (Actinopterygii, Cyprinidae), a new species of cyprinid fish
from Manyas Lake basin, Turkey
Abstract
Alburnoides manyasensis, sp. n., is described from the Koca
Stream (Lake Manyas drainage, Marmara Sea basin) in Anatolia. It is
distinguished from all species of Alburnoides in Turkey and adjacent regions,
Alburnoides tzanevi (Rezovska [Rezve], Istranca and Terkos streams in the
western Black Sea drainage), Alburnoides cf. smyrnae (Banaz Stream, a drainage
of Büyük Menderes River, Aegean Sea basin), Alburnoides fasciatus (streams and
rivers in the eastern Black Sea drainage) and Alburnoides eichwaldii (Kura and
Aras rivers [a drainage of Kura River], Caspian Sea basin) by a combination of
the following characters (none unique to the species):marked hump at nape,
especially in specimens larger than 60 mm SL; partly developed ventral keel
between pelvic fin and anal fin, scaleless 1/2 to 2/3 its length; body depth at
dorsal-fin origin 29−32% SL; caudal peduncle depth 11−12% SL; 45–52+ 2–3
lateral-line scales; 9–12 scale rows between lateral line and dorsal-fin
origin; 4–5 scale rows between lateral line and anal-fin origin, 10½–12½
branched anal-fin rays; 40–42 total vertebrae.
