It is distinguished from <i>Salmo</i> species in adjacent water by having 8-10 parr marks on flank; no red spots on flank in specimens larger than about 180 mm SL, if the red spot present in specimens larger than 180 mm SL, they are almost covered with black dots; number of black spots increasing with size, while number of red spots decreasing with size; a longer maxilla in males; a shorter predorsal length; fewer scale rows between dorsal-fin origin and lateral line; more scale rows between anal-fin origin and lateral line; and 16-19 gill rakers on first gill arch. <i>Salmo sengulae</i> sp. nov. was also compared the two closed species (<i>Salmo chilo</i> and <i>Salmo kottelati</i>) by using PCA analysis. The results of the PCA confirmed that <i>Salmo sengulae</i> sp. nov. differs from the other two species (<i>S. chilo</i> and <i>S. kottelati</i>). <i>Salmo sengulae</i> sp. nov. shares the same mtDNA Cyt <i>b</i> (991 bp) haplotype with <i>S. chilo</i> and <i>S. kottelati</i>. Additionally, genome-wide SNP data confirmed the separation of <i>S. sengulae</i> from those of Mediterranean trouts of Türkiye.Zoological studiese70https://www.ebi.ac.uk/biostudies/studies/S-EPMC12833488biostudies-literatureGenome-wide SNP Data and Integrated Morphology Reveal a New Trout Species from Ivriz and Berdan Streams, Turkiye.PMC12833488Guclu SSKucuk FKalaycı GTuran DKaba MOfalseGenome-wide SNP Data and Integrated Morphology Reveal a New Trout Species from Ivriz and Berdan Streams, Turkiye.<i>Salmo sengulae</i> sp. nov. is described from the Berdan (a drainage of Mediterranean Sea) and İvriz (a drainage of Konya closed basin) streams.
