Teleostei > Cypriniformes (Carps) > Xenocyprididae (East Asian minnows)
Etymology: longinasus: The specific epithet, used as a noun in apposition, is derived from the Latin longus (long) and nasus (snout), alluding to the presence of a long snout (length greater than eye diameter) compared with all other congeners.
Eponymy: Dr Charles William Metz (1889–1975) was an American zoologist, geneticist and taxonomist whose doctorate was awarded by Stanford University. He co-wrote: A catalog of the fishes known from the waters of Korea (1913). (Ref. 128868), visit book page.
