Play Ameerega petersi Call
Central Peru, found throughout much of the Ucayali drainage near Pucallpa. Though most common in the lowlands, a paratype was taken at 800 meters in the southeastern foothills of the Andes near Oxapampa, and we have found this species to be fairly common as high as 1350 m in some areas near Boqueron de Padre Abad just east of Tingo Maria.
Ameerega petersi is ecologically similar to other Ameerega, though appears to utilize slow-flowing water for tadpole deposition in some instances.
This species is common throughout its large range and is therefore not a primary conservation concern.
Nominal member of the petersi group, most closely related to A. cainarachi, although some analyses have placed it equally close to A. smaragdina.
There is substantial variation in stripe coloration within this species. Some populations have a pale yellow dorsolateral stripe, others spring-green, while some have a mint-green stripe. Upon its description in 1976, the range of this species was much larger than as currently defined. In the 1976 paper, Silverstone considered several paratypes collected near Tarapoto to be A. petersi, all of which are now known as A. pongoensis due to differences in calls and distribution. Much confusion still exists among Ameerega species that possess a green dorsolateral stripe. The marbling on the venter of A. petersi was used by Silverstone (1976) as the character diagnosing it from A. smaragdina, although this lack of marbling has now been observed in both species. This species also lacks shank spots, a characteristic mark of A. hahneli.
