Barbus xanthos, a new barbel from the Southern Aegean basin (Teleostei: Cyprinidae)

turan, davut/0000-0002-9586-6223WOS: 000541822600004PubMed: 31945184Barbus xanthos, a new species, is described from the Esen, Dalaman, Tersakan and Buyuk Menderes rivers in south-western Anatolia. It differs from otherBarbusspecies in the adjacent basins by having 53-60 lateral line scales, a weakly ossified last unbranched dorsal-fin ray (about 33-50%), numerous small irregular-shaped black or dark-brown spots smaller than scales, often forming large, black or dark-brown blotches on back and flank in juveniles and adults, and a straight or slightly convex posterior dorsal-fin margin.B. xanthosdiffers from its most closely related congener,B. pergamonensis, by nine nucleotide substitution sites in the mitochondrial DNA cytochrome oxidase I barcode region.This study was supported by a grant from the Suleyman Demirel Universitesi Scientific Research Projects Coordination Unit (Project No: SDU-BAP1987D09).

Capoeta aydinensis, a new species of scraper from southwestern Anatolia, Turkey (Teleostei: Cyprinidae)

GUCLU, Salim Serkan/0000-0002-9256-449X; Bektas, Yusuf/0000-0002-8367-9746WOS: 000402034800007Capoeta aydinensis sp. nov. is described from the Buyuk Menderes River and the streams Tersakan, Dalaman, and Namnam in southwestern Turkey. It is distinguished from all other Anatolian Capoeta species by the following combination of characters: one pair of barbels; a plain brownish body coloration; a well-developed keel in front of the dorsal-fin origin; a slightly arched mouth; a slightly convex lower jaw with a well-developed keratinized edge; a weakly ossified last simple dorsal-fin ray, serrated along about 60%-70% of its length, with 14-20 serrae along its posterior edge; 58-71 total lateral line scales; 11-12 scale rows between lateral line and dorsal-fin origin; 7-9 scale rows between lateral line and anal-fin origin.Recep Tayyip Erdogan University Scientific Research Projects Coordination UnitRecep Tayyip Erdogan University [2015.53002.103.01.06]We are pleased to thank Mufit Ozulug (Istanbul) for supporting this study with material and Jorg Freyhof for his comments on this manuscript.

Two New Species of Chondrostoma Agassiz, 1832 (Teleostei: Cyprinidae) from the Ceyhan, Seyhan and Goksu Rivers in the East Mediterranean Region of Turkey

GUCLU, Salim Serkan/0000-0002-9256-449XWOS: 000403575500015Chondrostoma toros sp.n. was described from the Goksu River. It was distinguished by a slightly arched lower jaw with a well-developed keratinized edge; a slightly developed keel in front of the dorsal-fm origin; lateral line with 56-64+1-3 scales; and 25-30 gill-rakers on outer side of first gill arch. Chondrostoma ceyhanensis sp.n. was described from Ceyhan, Seyhan and Berdan rivers. It was distinguished by its arched lower jaw with a slightly developed keratinized edge; a slightly developed keel between pelvic-fin and anus; lateral line with 59-66+1-3 scales; and 24-29 short gill-rakers on outer side of first gill arch.Scientific and Technological Research Council of Turkey (TUBITAK)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [KBAG-111T900]This study was supported by a grant from Scientific and Technological Research Council of Turkey (TUBITAK) (Project No: KBAG-111T900

Phylogeography of the genusChondrostomaAgassiz, 1835 (Teleostei: Leuciscidae) in Anatolia, as inferred from mitochondrial DNA analysis

WOS: 000550952000001The molecular phylogeny of the Anatolian species of the genusChondrostoma(Cypriniformes: Leuciscidae) was studied by sequencing of the mitochondrial cyt b gene. A total of 144 tissue samples from 14 described species were collected from 35 different localities in Turkey. in total, 74 cyt b haplotypes were identified. Haplotype network construction and phylogenetic analysis allocated all 14 species to two main haplogroups that are congruent with those currently accepted on the basis of morphological characteristics. the first haplogroup, the Nasus lineage, is distributed across Caucasia and the Black Sea and Marmara regions and is also represented in the Aegean basin. the second haplogroup, the Regium lineage, is distributed from eastern Anatolia to the Mediterranean Sea basin. Based on estimates generated in this study, the radical divergence between the mainChondrostomahaplogroups in Turkey occurred during the late Miocene (Tortonian stage) and late Pliocene Period, approximately 5.82 Mya (8.48-3.45 Mya). the splitting of the Nasus lineage occurred approximately 5.11 Mya, in the early Pliocene, and the Regium Lineage diverged from its sister group, the Nasus lineage approximately 4.77 Mya. the primary diversification events for the species belonging to these two haplogroups occurred in the Late Pliocene to Early Pleistocene which coincides with the uplifting of the Anatolian plateau about 2.5-3.0 Mya.Scientific and Technological Research Council of Turkey (TUBITAK), Directorate of Academic Research Funding Programmes (ARDEB)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [KBAG-111T900]This study was funded by a government grant from the Scientific and Technological Research Council of Turkey (TUBITAK), Directorate of Academic Research Funding Programmes (ARDEB) (Project No: KBAG-111T900)

A new Chondrostoma species from the Buyuk Menderes River Basin, Turkey (Teleostei: Cyprinidae)

GUCLU, Salim Serkan/0000-0002-9256-449XWOS: 000445800000004In a study of the fishes of the Buyuk Menderes River Basin, Aegean region of Turkey, two populations of Chondrostoma were found which showed clearly distinctive characters: the population from the Upper B. Menderes (Ikl Lake) was attributed to C. meandrense Elvira, 1987, while the population from the Cine Stream in the Lower B. Menderes River basin proved to be a hitherto undescribed species: Chondrostoma turnai sp. n. Altogether 24 metric and 7 meristic parameters were compared. the new species is distinguished from C. meandrense and all other cogeners by a combination of the number of lateral line scales, the number of scale rows between the lateral line and the dorsal-fin origin, the number of scale rows of the lateral line and pelvic-fin origin, and the number of gill rakers on the first gill arch.http://www.zoobank.org/urn:lsid:zoobank.org:pub:811C213D-BEDD-4C8C-AE57-BFFA7964781AScientific and Technological Research Council of Turkey (TuBTAK)Turkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK) [KBAG-111T900]This study was supported by a grant from the Scientific and Technological Research Council of Turkey (TuBTAK) (Project No: KBAG-111T900)
