Name
Alburnoides manyasensis Turan & Ekmekçi & Kaya & Güçlü, 2013 sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Holotype
FFR 01069. Female. 82 mm SL; Turkey, Balıkesir Prov., Koca Stream at outlet of Manyas Dam Lake, Lake Manyas drainage; 39°59'26"N, 27°47'58"E, 11 July 2007, coll. D. Turan and R. Buyurucu.
Paratypes. FFR 01073, 24, 54–92 mm SL; same data as holotype.
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, 10½–12½ branched anal-fin rays; pharyngeal teeth 4.2–2.4, markedly hooked; total vertebrae 40–42: 20–22, with mode of 21, abdominal and 19–21, with mode of 20, caudal vertebrae.
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 8−10: 2–3 + 6–7 on outer side of first gill arch. Dorsal fin with 3 simple and 8½, rarely 7½ or 9½, branched rays; its depth 21–27% SL, outer margin straight or slightly concave. Pectoral fin long, not reaching pelvic-fin origin in both sexes, its length 20–24% SL, outer margin slightly convex, with 12–13 branched rays. Pelvic fin rounded, reaching or slightly behind anus, with 1 simple and 7 branched rays. Anal fin with 3 simple and 10½–12½ branched rays, outer margin concave. Caudal fin forked, lobes slightly pointed.
Pharyngeal teeth 4.2–2.4, markedly hooked. Total vertebrae 40–42; predorsal vertebrae 13–15 with mode of 14; number of abdominal vertebrae 20–22 with mode of 21, and that of caudal vertebrae 19–21 with mode of 20 (frequency of occurrence of character states given in Table 3). Abdominal region longer than caudal region, rarely regions equal, and difference between abdominal and caudal counts varying from 2 to –1; most common vertebral formula 21+20.
Sexual dimorphism. There are small tubercles on rays of anal fins in male. The length of the paired fins does not display any statistically significant difference in males and females as it often occurs in other Alburnoides species.
Coloration. Formalin preserved adults and juveniles brownish on back and upper part of flank, yellowish on lower part of flank and belly. Caudal and dorsal fins light grey; pectoral, pelvic and anal fins yellowish. Spots along lateral line above and below pores slightly distinct in anterior part of body but indistinct in posterior part. Dark grey stripe (its width approximately equal to eye diameter) on upper part of flank from posterior margin of operculum to caudal peduncle, slightly distinct in anterior body part but clearly distinct in posterior part. No or few dark pigment dots on each scale pocket below lateral stripe.
Distribution and notes on biology
Alburnoides manyasensis is known only from the Koca Stream, drainage of Lake Manyas, Marmara Sea basin (Fig. 1).It inhabits clear fast running water with cobble and pebble substrates. Capoeta tinca (Heckel, 1843), Barbus oligolepis Battalgil, 1941, Squalius cii (Richardson, 1857), Vimba vimba (Linnaeus, 1758), Chondrostoma sp., Rhodeus amarus (Bloch, 1782), Oxynoemacheilus sp. and Alburnus sp.were collected together with Alburnoides manyasensis.
Etymology
The name of the species, an adjective, is derived from the name of Lake Manyas. {| class="wikitable" ; style="width: 100%" |+ Table 1.
