Nanorana is a genus of dicroglossid frogs. They are found in Asia, from the Himalayan region of northern Pakistan and northern India, Nepal, and western China east to montane southern China and southeast to Myanmar, Thailand, Laos, and northern Vietnam. Common names of these frogs reflect the complex taxonomic history of the genus (see below) and include Yunnan slow frogs (or simply slow frogs) and High Himalaya frogs (for the now-synonymized genus Altirana).[1]


The taxonomy of true frogs and their allies has been subject to numerous changes during the last decade and is not yet fully settled. Nanorana in particular has seen big changes. As currently delineated, Nanorana is a quite large genus with 28 species, resulting from considering Chaparana, Paa, and Feirana as junior synonyms. Currently these taxons may be recognized as subgenera, but their delineation is not entirely settled and not all species have been assigned to subgenera. Note, however, that species at one point placed in these (sub)genera might currently be placed also in genera other than Nanorana (Quasipaa, Ombrana, and Allopaa).[1]


Currently 27[2] or 28[1] species of Nanorana are recognized:

Nanorana fansipani (Bourret, 1939) is synonym of N. aenea.
