Abstract
Turcinoemacheilus ekmekciae, new species, from upper Euphrates and Tigris drainages is distinguished from other species of Turcinoemacheilus in Western Asia by having a dark stripe broader than the eye diameter along the lateral line, rarely possessing roundish blotches, 5-6 mandibular pores in mandibular canal, a comperatvely smaller head, a deeper body, and a greater pre-pelvic distance. Our specimens collected from the upper Great Zab, near the type locality of Turcinoemacheilus kosswigi, showed notable genetic divergence (a minimum K2P of 3.3%) from sequences reported as T. kosswigi in previous studies. Despite morphological similarities, this molecular difference suggests that the populations analysed in previous studies may represent a potential new species of Turcinoemacheilus, which we tentatively named as Turcinoemacheius cf. kosswigi. Molecular data also suggest that T. ekmekciae is characterized by a minimum K2P distance of 3.5% from Turcinoemacheilus minimus and T. cf. kosswigi. The three methods for species delimitation (assemble species by automatic partitioning [ASAP], Poisson tree processes [PTP], and multi-rate PTP [mPTP]) that were utilized for testing species assignments consistently identified our test group as a distinct species.

Abstract
Phoxinus abanticus, a new species, is described from the Lake Abant basin. It is distinguished from Phoxinus species in Türkiye and adjacent waters by the presence of fewer lateral line scales (60-69, vs. 75-91 in Phoxinus colchicus, 75-90 in Phoxinus strandjae); a deeper caudal peduncle (caudal peduncle depth: 1.8-2.3 times in length, vs. 2.4-2.9 in P. colchicus; 2.5-3.2 in P. strandjae); the absence of scales in the breast of males (vs. present); and ventral body reddish in nuptial colouration pattern for male (vs. brackish). The new species, P. abanticus, is also distinguished from its closest relative, P. strandjae, by a minimum of 3.40% genetic distance in the mtDNA cytochrome b (cyt b) gene.

Abstract
A new amphipod species belonging to the genus Gammarus is described from the Gökgöl Cave, Zonguldak Province, Türkiye. The newly-identified species is relatively small (13 mm) and is a member of the Gammarus pulex-group by the presence of numerous long setae along the posterior margins of pereopods 3 and 4. The specimens were sampled from a shallow pond located in the dark zone (about 1 km inside the entrance) of the cave. Minute eyes, setose (both peduncle and flagellar segments) second antenna, slightly swollen flagellar segments of the second antenna, setose pereopods 3 and 4 and relatively short endopod/exopod ratio of the third uropod are the character combination of the newly-identified species in addition to lacking body pigmentation. The molecular phylogeny, based on the concatenated dataset (28S+COI, 1495 bp) indicated that the new species was resolved from the other Gammarus species by high bootstrap (NJ: 100, ML: 100). In addition to Gammarus tumafsp. nov., mtDNA COI and nuclear DNA 28S gene data of Gammarus baysaliÖzbek et al., 2013 were recorded for the first time. The newly-identified species was well-differentiated from the genetically closest species, G. baysali, with genetic distance of 12.22% and 0.55% for the COI and 28S genes, respectively. Detailed descriptions and drawings of the extremities of the holotype male were given and the morphology of the newly-identified species is compared with its relatives.

Abstract
The DNA barcoding approach was used for the determination of evolutionary relationships and species delimitation of the genus Oxynoemacheilus (Teleostei: Nemacheilidae). The COI barcode region (615 bp amplicon) was used to barcode 444 individuals from 64 morphologically identified species in the genus Oxynoemacheilus and 189 haplotypes were identified. The average of the interspecific p distance (9.59%) was about 21-fold higher than the average intraspecific distance (0.44%). A general genetic threshold of 1.46% sequence divergence was defined for species delimitation. The multiple species delimitation methods (BCM, GMYC, bPTP and TCS) revealed a total of 62 molecular operational taxonomic units for 64 morphospecies with a new loach species from the BuyukMelen River. Neighbour-joining, maximum likelihood and Bayesian inference analyses indicated that all haplotypes were clustered into 62 clades, which corresponded to Oxynoemacheilus species, with strong bootstrap support (≥95%). Furthermore, all samples grouped in concurrence with the taxonomic status of the species except for species groups (O. germencicus-O. cinicus-O. mesudae and O. leontinae-O. namiri) that were showed intraspecific overlap in genetic diversity for COI-based barcodes. In conclusion, our analyses indicate that COI-based barcodes provide reliable species discrimination. Therefore, we currently recommend COI barcodes as the suitable barcode for genus Oxynoemacheilus.

Abstract
The molecular and morphological studies carried out within the scope of this study revealed that the scrapers, known as the Mesopotamian group, belong to a different genus. The Paracapoetagen. nov., from the Mesopotomia and Levant, is distinguished from Capoeta and Luciobarbus species by the presence of a strong ligament between the base of the last simple and the first branched rays of the dorsal-fin (vs. no or a very weak ligament). The Paracapoeta further differs from Capoeta by the last simple dorsal-fin ray strongly ossified in adult specimens (more than 75%, vs. less than 75%). The Paracapoeta further differs from Luciobarbus by the lower lip with horny layer (vs. fleshy lips). The molecular phylogeny based on the combined dataset (COI + Cytb, 1312 bp.) showed that the genus Paracapoeta was recovered from the other groups in the subfamily Barbinae with high bootstrap and posterior probability values (BP: 94%, PP: 0.96). Also, Paracapoeta and Capoeta are well differentiated by an average genetic distance of 8.02±0.78%. The morphological and molecular findings have largely overlapped each other. Besides, Capoeta turani is treated as a synonym of Capoeta erhani.

Abstract
Turcichondrostoma, a new genus, from the Southwestern Anatolia is distinguished by having fewer gill rakers on first gill arch and morphologies of premaxilla and dentary bones. In addition, as a result of the phylogenetic analyses based on combine data set (mtDNA COI + Cytb) sequences (1706 bp.), Turcichondrostoma genus was recovered with high posterior probability value (BI PP:1.0) and strong-supported bootstrap value (ML BP: 100%) among the former Chondrostoma groups. Also, high K2P mean genetic distance values (more than 7.84%) differentiated genus Turcichondrostoma from the other genera of former Chondrostoma group. The results of both morphological-osteological and molecular analyses are congruent with each other. The results of this study revealed that the genus Turcichondrostoma is easily distinguished from the genera in Chondrostoma group.

Abstract
In an effort to reveal the Euphrates trout taxonomy, the Karasu River, which is one of the eastern drainages of the river, was investigated and three independent populations were identified. Result revealed that two populations belonged to Salmo munzuricus, which was known only in Munzur River, while the other population belonged to an unnamed species. Salmo baliki, a new species, is described from the Murat River, a drainage of Euphrates River. It differs from Salmo species in adjacent water by the combination of the following characters: a grayish body; commonly one, rarely two pale black spots behind eye and on cheek; two to seven black spots on opercle; a few black spots on back and upper part of flank, missing on predorsal area; few to numerous large irregular-shaped red spots in median, upper and lower part of flank, surrounded by a large irregular-shaped white ring; the number of black and red spots not increasing in parallel with size; maxilla short and narrow; adipose-fin medium size, no or rarely one or two red spot its posterior edge; 107–118 lateral line scales; 24–28 scales rows between dorsal-in origin and lateral line; 18–22 scale rows between lateral line and anal–fin origin; maxilla length 7.7–9.1% SL in males, 8.2–9.6 in females. Finally, the genetic study of the Cyt b mitochondrial gene confirmed the morphological data, suggesting the separation of S. baliki from other Salmo species.

Abstract
Oxynoemacheilus cemali sp. nov. is described from the Çoruh River drainage in the eastern Black Sea basin. One molecular marker (coI), 25 morphometric and four meristic characters were analysed. Oxynoemacheilus cemali is distinguished from O. kosswigi, O. banarescui, O. samanticus and O. angorae in the Black Sea basin by having a suborbital groove in males, an axillary lobe at the pelvic-fin base, no dorsal adipose crest on the caudal peduncle, a slightly-forked caudal fin and 7-15 dark grey dorsal saddles. Morever, Oxynoemacheilus cemali is distinguished by commonly having 9-15 irregularly-shaped dark-grey bars on the flank posterior to the dorsal-fin origin or, rarely having a mottled pattern or 4-6 irregularly shaped dark-grey bars on the flank posterior to the dorsal-fin origin. Oxynoemacheilus cemali is also distinguished from the closely related species O. araxensis and O. cyri, distributed outside the Black Sea basin, by having 15 and 31 diagnostic nucleotide substitutions in the coI barcode region, respectively.
