A few studies have looked at this genus with a larger geographic perspective, such as that of Levin et al. (2012), who provided a phylogenetic framework of the genus. Alwan (2010) intensively studied the C. damascina species group, and Geiger et al. ( 2014) provided additional molecular data on Mediterranean species of Capoeta. Alwan (2010) conclusively demonstrated that C. angorae from the Mediterranean basin is a synonym of C. damascina, a view also supported by Levin et al. (2012) and Geiger et al. (2014).However, despite all these studies, the species diversity of Capoeta in Anatolia has not been fully resolved, and both Levin et al. (2012) andGeiger et al. (2014) found one group of populations in the Büyük Menderes and Dalaman rivers that was well distinguished from its sister species, C. bergamae, by the molecular methods applied. Here we study Capoeta from the Büyük Menderes River as well as from the streams Dalaman, Tersakan, and Namnam, with the aim of testing whether this molecular lineage might be a species different from C. bergamae and other Capoeta species of the Mediterranean Basin and adjacent Central Anatolia.
Materials and methodsFish were caught using pulsed DC electrofishing equipment. The material is deposited in the Recep Tayyip Erdoğan University Zoology Museum of the Faculty of Fisheries, Rize (FRR) and İstanbul University, Science Faculty, Hydrobiology Museum, İstanbul (IUSHM). Measurements were made using digital calipers (0.1 mm accuracy). Hubbs and Lagler (1947) were followed in counts and measurements except as follows: head width at anterior eye margin: distance between anterior margins of eyes; head width at posterior eye margin: distance between posterior margins of eyes; head depth: through eye; snout width: at level of nostrils; head depth at snout: at level of nostrils; mouth width: measured between corners of mouth. Lateral line scale count includes scales on the caudal-fin base. The last 2 branched dorsal-and anal-fin rays, which articulate on a single pterygiophore, were counted as 1½. In the descriptions, numbers in parentheses after a count indicate the number of specimens in which this count was observed. To determine the sex of fishes, gonads were checked under a stereomicroscope.Morphometric and meristic data of C. damascina, C.
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.
Pseudophoxinus burduricus
sp. n. is described from drainages of Salda and Burdur lakes, southwestern Turkey. It is distinguished from other Anatolian Pseudophoxinus by a combination of characters: lateral line incomplete, with 21–39 (commonly 26–37) perforated scales and 47–57+1-2 scales in lateral series; 10½–12½ scale rows between lateral line and dorsal fin origin, 3–4(5) scale rows between lateral line and the pelvic fin origin; dorsal fin commonly with 7½ branched rays; anal fin commonly with 6½ branched rays; 7–8(9) gill rakers on the first branchial arch; a faint and diffuse epidermal black stripe from eye to caudal fin base in alive and preserved individuals; mouth slightly subterminal, tip of mouth cleft on about level of lower margin of eye; snout rounded, its length greater than eye diameter. Comparison is given with all Pseudophoxinus species from western Anatolia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
