Danio erythromicron, often known as emerald dwarf danio and emerald dwarf rasbora, is a species of freshwater ray-finned fish belonging to the family Danionidae. This fish is endemic to Inle Lake in Myanmar.
Taxonomy and systematics
[edit | edit source]In 1999, it was suggested that the species be transferred to the genus Danio based on morphological data, but it was cautioned that more research would be necessary.[4] A phylogenetic analysis of Danio found it indeed close to that genus, but its precise placement was still indeterminable.[5] Shortly thereafter, a new species, Danio margaritatus, was described under the name Celestichthys margaritatus.[6] However, this new species was quickly moved into Danio following further analysis.[7] Subsequent analysis of DNA sequence data showed that Microrasbora erythromicron was related to Danio, and recommended moving this species to that genus.[8] Later molecular analysis confirmed its placement within the genus, with its closest relatives being Danio margaritatus and Danio choprai.[9]
