The only "Danio" species to have been consistently called "Danio" were "D. dangila" and "D. feegradei". As "D. dangila" was the first discovered "Danio" (or type) the name "Danio" had to remain with "D. dangila", which is why the vast majority of species were moved to "Devario". Also, the sister group to "Devario" was deemed to be a clade formed by "Inlecypris" and "Chela", and more
