Capoeta tinca (Heckel, 1843)

Types. Lectotype: Naturhistorisches Museum Wien 55931:1, designated by Banarescu & Herzig-Straschil

(after Banarescu, 1999).

T y p e L o c a l i t y. “Brussa in Natolien”

Diagnosis. Meristic characters (tab. 1–4): D: III 8 (8.0), P: I 18–20 (18.8), V: I 8–9 (9.0), A: III 5, lateral line: 69–80 (74.9), scales number above/below lateral line: 14–17 (15.7)/9–11 (9.5).

C. tinca , previously known from the Rioni and Chorokh rivers was revised recently and noted only for the Marmara Sea basin in Turkey. This species is distinguished from the Capoeta species of East and South- East Black Sea rivers ( C. svanetica sp. n., C. sieboldi , C. oguzelii , C. baliki , C. ekmekciae , and C. banarescui ) by the combination of characters. Two pairs of barbels ( C. sieboldi and C. oguzelii have only one pair); gill rakers number (19–23 (20.6)) higher than in C. svanetica sp. n., C. banarescui , C. baliki and C. oguzelii but fewer than for C. sieboldi ; last unbranched dorsal-fin ray well ossified with the high number of serrae (unlike C. sieboldi and C. oguzelii ); 14–17 scales above the lateral line are highest than in C. svanetica sp. n., C. banarescui and C. sieboldi ; 9–11 scales rows below lateral line are highest than in C. svanetica sp. n. and C. banarescui . C. tinca also characterized by less length of anterior and posterior barbels 8.1–14.1 (mean 10.6) and 13.1–19.3 (mean 15.4) respectively than the same parameter for C. svanetica sp. n. (13.9–20.1 (mean 16.7) / 18.7–28.6 (mean 22.2)) and C. banarescui (12.4–20.8 (mean 16.9) / 18.4–28.8 (mean 21.9)).

Distribution. C. tinca is known from the rivers draining to the southern shore of the Sea of Marmara ( Turan et al., 2006 b).
