Raxml tree for the coxI gene of the five species of Danionella (upper lef) from different sampling locations (data set 1) and map (upper right) showing type localities (large circles) and locations of additional samples (small circles). Note that both species, D. cerebrum and D. translucida, co-occur at each other’s type locality. Roadside canal at Hmawbi (lower lef), type locality of D. cerebrum, and Daikme Chaung (lower right), type locality of D. translucida, illustrating the typical turbid streams in which these two species occur.
