It was described in 2017 by the herpetologist Matheus Neves and his colleagues, and is named after the Munduruku, an ethnic group native to Brazil.

Ameerega munduruku was described by the herpetologist Matheus Neves and his colleagues in 2017 on the basis of an adult male specimen collected from Pará, Brazil, in 2016.

It is named after the Munduruku, an ethnic group living in the Brazilian states of Pará and Mato Grosso.

[5] The following cladogram shows relationships within this clade based on a phylogeny by a 2020 study:[5] A. boliviana Ameerega sp.

When preserved in 70% ethanol, the orange markings on the underside and the cream stripe on the upperside are duller in colour and the iris is grey.

[3] The species can be identified as a member of its genus by its aposematic colouration, a bright spot near the calf, a light stripe along the upperside, no pale line along the sides, the absence of webbing, and the presence of palatine teeth.

It can be told apart from other species in its genus by a combination of its medium size; a snout that is short when seen from above and projecting when seen from the side; a black upperside; a white underside with black markings; the presence of the orange spots and stripe; only the lower portion of the ring of the tympanum (external ear) being visible and the fold above the tympanum being absent; and small hands with well-developed discs on the fingers.

The calls are mainly delivered at a frequency of 3,445.3–3,617.6 Hz, helping tell the frog apart from A. altamazonica, A. berohoka, A. boehmei, A. braccata, and A.

[3] Frogs known to co-occur with A. munduruku include Ceratophrys cornuta, Lithodytes lineatus, Allobates tapajos, Proceratophrys korekore, and species in the genus Adenomera.
