diagnosis

Diagnosis. Distinguished from other species of Alburnoides in Mediterranean, Marmara, and Black Sea basins by: ○ ventral keel scaleless up to half its length, rarely almost completely or completely covered by scales / ○ body depth at dorsal origin greater than head length / ○ horizontal eye diameter usually slightly to markedly larger than interorbital distance / ○ snout short, pointed / ○ mouth terminal / ○ tip of mouth cleft situated at a horizontal line with middle of pupil or slightly below / ○ 45 − 52 + 2 − 3 lateral-line scales / ○ caudal peduncle depth 11 – 12 % SL / ○ lateral line clearly distinct in both, anterior and posterior parts / ○ snout length about equal to interorbital distance / ○ 4 pharyngeal teeth in long row on right 5 th ceratobranchial / ○ 10 − 12 ½, usually 12 ½, branched anal rays / ○ 6 − 10, usually 8 – 10, gill rakers. Size up to 92 mm SL.

description

Description. Maximum known size 92 mm SL. General appearance shown in Fig. 3; morphometric and meristic data given in Tables 1 and 3. Body deep, its depth at dorsal-fin origin 29 - 32 % SL, mean 29.4, at anal-fin origin 22 - 27 % SL, mean 24.4, and markedly compressed. Dorsal profile markedly convex with marked hump at nape in specimens larger than 60 mm SL, ventral profile less convex than dorsal profile. Predorsal length 52 - 58 % SL, mean 54.2. Caudal peduncle deep, its depth 11 - 12 % SL, mean 11.5. Head short, its length 25 - 27 % SL, mean 26.0, approximately 0.8 - 0.9 times body depth at dorsal fin origin, dorsal profile straight or slightly convex at interorbital area, slightly convex at snout. Snout short, slightly pointed, its length 6 - 8 % SL, mean 6.8, shorter than both eye diameter (eye diameter 7 - 9 % SL, mean 8.2) and interorbital width (interorbital width 7 - 8 % SL, mean 7.7). Mouth terminal, with very slightly marked chin, its corner reaching vertical through anterior margin of pupil. Lateral line with 45 - 52 + 2 - 3 scales; (9) 10 - 12 scales rows between lateral line and dorsal-fin origin; 4 - 5 scales between lateral line and anal-fin origin. Gill rakers 8 −

diagnosis

Diagnosis. Alburnoides manyasensis is distinguished from all the species of Alburnoides in Turkey and adjacent areas by a combination of the following characters (none unique to the species): partly or slightly developed ventral keel between pelvic fin and anal fin, scaleless about 1 / 2 to 2 / 3 its length; upper body profile markedly convex, with marked hump at nape, especially in specimens larger than 60 mm SL; upper head profile straight or slightly convex in interorbital area, slightly convex on snout; corner of mouth reaching vertical through anterior margin of pupil; snout with slightly pointed tip; interorbital width 7 - 8 % SL; dark grey stripe indistinct or slightly distinct in anterior part of body but distinct in posterior body; pigmentation of lateral line slightly distinct in anterior part of body but indistinct in posterior part of body (Fig. 3) in most of specimens; 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, 101 / 2 - 121 / 2 branched anal-fin rays; pharyngeal teeth 4.2 - 2.4, markedly hooked; total vertebrae 40 - 42: 20 - 22, with mode of 21, abdominal
