Elachistocleis muiraquitan was recently described from fifteen specimens found at two sites in Acre state, northwestern Brazil. Prior to the description of E. muiraquitan, individuals fitting the description of this species found in southeastern Peru and northwestern Bolivia were identified as Elachistocleis bicolor, a species associated with markedly different habitat and environmental conditions. Here, we re-identified these specimens and also propose the first map of E. muiraquitan’s potential distribution, based on known localities along with climatic and environmental parameters.
