Ameerega rubriventris Lötters et al. 1997
Distribution: Central Peru, eastern foothills of the Cordillera Azul at elevations around 350 m. The range of this species appears to be highly restricted. View type locality in Google Maps.
Ecology: Like A. hahneli, this species is active during the day among the leaf litter. Though we only were able to observe this species in the wild for a short time, it presumably is similar to A. hahneli in its reproductive habits.
Phylogenetic status: Forms a clade sister to the montane clade of A. hahneli.
Conservation status: Though not likely to be under high smuggling pressure, the small range of this species could be easily affected by local deforestation.
Notes: Until 1997, this was considered to be a morph of A. hahneli, until Lötters made the distinction based on the ventral coloration and vocalization. The status of A. rubriventris as a valid species is still in dispute by some, though the unusual ventral colors and genetic distinctness suggest that this species is indeed different from the morphologically conserved A. hahneli.
