Nanohyla nanapollexa is a species of frog in the family Microhylidae. It is also known as the no-thumb pigmy frog and three-fingered pigmy narrow-mouth frog. It is endemic to Vietnam and is known from Quang Nam and Phu Yen Provinces.
N. nanapollexa was formerly placed in the genus Microhyla, but a 2021 study using morphological and phylogenetic evidence moved nine species (including N. nanapollexa) to a new genus, Nanohyla.[1]
The type locality of Nanohyla nanapollexa is a montane broad-leaved evergreen forest with small mixed coniferous areas at 1480m (4,860feet) above sea level. N. nanapollexa is considered data deficient by the IUCN Red List.
