Pristimantis riveti

Pristimantis riveti is a species of frog in the family Strabomantidae. It is endemic to Ecuador and as currently understood, only known with certainty from its type locality, Mount Mirador near the border between Carchi and Sucumbíos Provinces.^[2][3][4] Records from elsewhere (e.g., IUCN Red List^[1]) represent other species, including Pristimantis lutzae.^[4] Common names Despax's robber frog^[2] and Riveti robber frog have been proposed for it.^[3]
