Nanohyla

Nanohyla is a genus of frogs in the family Microhylidae. Members of the genus are known as pygmy narrow-mouthed frogs. The members of the genus are found throughout Southeast Asia in the countries of Vietnam, Laos, Cambodia, Thailand, Malaysia, Brunei, Indonesia and the Philippines.

Taxonomy
All the members of Nanohyla were formerly placed in Microhyla; however, a 2021 study used morphological and phylogenetic evidence to show that Nanohyla forms a separate lineage from Microhyla and Glyphoglossus.
