Dendropsophus arndti is a species of "clown tree frogs"[3] described in 2017[2] that lives in the Amazon basin of Bolivia, Peru, and Brazil.

[1][4] The specific name arndti honors professor Rudolf G. Arndt, in recognition of his financial support for research and nature conservation.

[2] This species is found in the Amazon basin of southeastern Peru, Bolivia (Beni and Santa Cruz Departments)[1][4] and western Brazil (Rondônia, possibly east to Mato Grosso).

[2] Dendropsophus arndti has been recorded in Beni savanna, Chiquitano dry forests, and Bolivian Yungas at elevations of 148–529 m (486–1,736 ft) above sea level.

The IUCN Red List of Threatened Species classifies Dendropsophus arndti as of "least concern" because of its relatively wide distribution in mostly intact habitat.
