Özet

Salmo sengulae sp. nov. is described from the Berdan (a drainage of Mediterranean Sea) and İvriz (a

drainage of Konya closed basin) streams. It is distinguished from Salmo 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. Salmo sengulae was

also compared the two closed species (Salmo chilo and Salmo kottelati) by using PCA analysis. The

results of the PCA confirmed that Salmo sengulae differs from the other two species (S. chilo and S.

kottelati). Salmo sengulae shares the same mtDNA Cyt b (991 bp) haplotype with S. chilo and S. kottelati.

Additionally, genome-wide SNP data confirmed the separation of S. sengulae from those of Mediterranean

trouts of Türkiye.
