Collection: Pensoft Publishers

Keywords: benthic species · Topics: Identification and Quantification in Food, Fish Biology and Ecology Studies, Fish Ecology and Management Studies

Limnichthys koreanus sp. nov. is described on the basis of the holotype and 11 paratypes from subtidal waters of Seogwipo, Jeju Island, Korea. The new species had previously been regarded as the Northern Hemisphere population of the anti-equatorial L. fasciatus, but molecular analyses of mitochondrial COI and 16S genes recovers deep genetic divergences of 9.4% and 15.0% between the new species and topotypical specimens of L. fasciatus. Limnichthys koreanus sp. nov. is distinguished from all other species of Limnichthys based on the following combination of colouration and morphological characteristics: 38-40 vertebrae; 0–6 dorsal saddles joining mid-lateral stripe; small infraorbital sensory pores; a single median interorbital pore; and well-developed vomerine teeth. Summary characters for comparative congeneric species are provided.
