Coreoleuciscus aeruginos (Teleostei: Cypriniformes: Cyprinidae), a new species from the Seomjin and Nakdong rivers, Korea

Abstract

Coreoleuciscus splendidus was first reported as a monotypic species. Recent morphological and genetic studies have revealed that the species is represented by two disjunct and distinct lineages. The two lineages of C. splendidus include populations inhabiting the Han and Geum rivers in the East Korea Subdistrict and populations inhabiting the Seomjin and Nakdong rivers in the South Korea Subdistrict. In this study, significant differences were found between these two independent lineages through a high degree of genetic divergence in the mitochondrial cytochrome c oxidase subunit I gene as well as conspicuous morphological differences in body coloration and shapes of black stripes on dorsal, anal and caudal fin rays. These morphological and genetic differences provide supporting evidence that the populations in the South Korea Subdistrict represent a new species, Coreoleuciscus aeruginos.

Characterization of the complete mitogenome of the endangered freshwater fish Gobiobotia naktongensis from the Geum River in South Korea: evidence of stream connection with the Paleo-Huanghe

“…The two G. naktongensis populations from the two major river systems, the Geum and Nakdong rivers in the West Korea and South Korea subdistricts, respectively, also showed the same biogeographical distribution pattern as those of Coreoleuciscus and Koreocobitis (Kim and Bang 2012 ; Kim et al 2012 ). Each of the two species in both genera was erected as a novel species based on further taxonomic studies, as well as significant genetic divergence (Kim et al 2000 ; Song and Bang 2015 ).…”

Complete mitochondrial genome of the Korean endemic species Coreoleuciscus aeruginos holotype from Korea (Cypriniformes, Cyprinidae)

“…Coreoleuciscus aeruginos (family Cyrinidae) is an endemic Korean freshwater fish distributed in riffles of the middle and upper reaches of the Seomjingang and Nakdonggang River systems. A single C. aeruginos specimen was previously reported as C. splendidus (Mori 1935), but was later described as a new species with significant morphological and genetic differences from Coreoleuciscus splendidus (Song and Bang 2015). This study first reports the complete mitogenome of the C. aeruginos holotype and provides the phylogenetic location of genus Coreoleuciscus.…”
