TL;DR: Comparative analysis with Lake Ohrid brown trout supported the notion that these fish have more recently colonized the lake and phylogenetically belong to the Adriatic lineage of brown trout, and suggested that species-specific saturation in the mtDNA control region underestimated the divergence between S. ohridanus and S. trutta.
Abstract: Analysis of both uni- (two mtDNA gene sequences) and bi-parentally (seven microsatellite loci) inherited genetic markers, together with analysis of 40 morphological characters, described Salmo ohridanus as a highly divergent member of the genus Salmo. Based on comparative substitution rate differences at the cytochrome b gene, and a rough estimated age of the Salmo trutta complex (i.e. at least 2 million years), the S. ohridanus and Salmo obtusirostris clade probably split from a common ancestor of brown trout Salmo trutta >4 million years ago, overlapping with minimum age estimates of the formation of Europe's oldest freshwater habitat, Lake Ohrid. Comparative analysis with Lake Ohrid brown trout (known regionally as Salmo letnica), supported the notion that these fish have more recently colonized the lake and phylogenetically belong to the Adriatic lineage of brown trout. It is further suggested that species-specific saturation in the mtDNA control region underestimated the divergence between S. ohridanus and S. trutta. Evidence of rare hybridization between S. ohridanus and Lake Ohrid brown trout was seen at both mtDNA and microsatellite markers, but there was no support for extensive introgression.

TL;DR: In this article, an analysis of both uni-and bi-parentally inherited genetic markers, together with analysis of 40 morphological characters, described Salmo ohridanus as a highly divergent member of the genus Salmo.
