[Ichthyology • 2014] Tanakia latimarginata • A New Species of Bitterling (Teleostei: Cyprinidae) from the Nakdong River, South Korea

Tanakia latimarginata
Kim, Jeon & Suk, 2014

 Tanakia latimarginata, new species, is described from the Nakdong River, South Korea. It is distinguished from closely related species in that it has a black distal margin on the anal-fin of mature males that is greater than the diameter of the pupil posteriorly to the midpoint of the fin, a light colored ovipositor in mature females, an irregularly shaped fifth infraorbital bone, and a parietal branch of the supraorbital sensory canal that reaches to or extends past the border between the frontal and parietal. Phylogenetic analyses utilizing mitochondrial (cytochrome b) and nuclear (myh6) DNA sequences support a sister group relationship between T. latimarginata and T. lanceolata.
