Rhaebo olallai is a species of toad in the family Bufonidae endemic to Ecuador. Its common name is Tandayapa Andes toad, after its type locality, Tandayapa, in the Pichincha Province);[2] the species has not been seen there after 1970, despite search efforts.[3][4] It is only known from another locality in the Imbabura Province of Ecuador (Manduriacu River).[2][3][5] It has also been reported from one locality on the Colombian Massif, Nariño Department, Colombia, but these have been shown to represent Rhaebo colomai.[4]
Description
Rhaebo olallai are medium-sized toads: males measure 37–38 mm (1.5–1.5 in) and females 57–60 mm (2.2–2.4 in) in snout–vent length. Dorsum is coffee-coloured. The parotoid glands are enlarged and conspicuous. Flanks have conspicuous glands, distributed linearly or irregular patterns.[5]
Habitat and conservation
Its natural habitat are tropical premontane forests of western foothills of the Andes.[5] All individuals of the Manduriacu River population were found near small forest streams, perched on branches or leaves, on average 1.4 metres but up to 4 metres over ground.[3]
It is threatened by habitat loss caused by agriculture and logging,[1] and by mining and hydropower. Only one population is known. The species is classified as "Critically Endangered".[4]
