Brachycephalus nodoterga

Brachycephalus nodoterga, the Serra Cantareira saddleback toad, is a species of frog in the family Brachycephalidae. It is endemic to the eastern São Paulo state (both the mainland and Ilha de São Sebastião) of southeastern Brazil, where only known from five locations in Atlantic rainforest at an altitude of 700–900 m (2,300–3,000 ft).[2][3] Little is known about its behavior, but like other saddleback toads it lives among leaf litter.[4] Its conservation status was last reviewed by the IUCN in 2004 where regarded as data deficient (insufficient information for rating it),[1] but an independent review in 2019 that used IUCN's criteria recommended that B. nodoterga should be recognised as vulnerable.[2]

This tiny toad has bumpy skin and an overall yellow-orange colour, with its upperparts generally tending towards a duller and darker brownish-green hue.[2][3][5] Unlike the more conspicuously coloured B. ephippium and B. pernix, studies of B. nodoterga have not detected toxins in its skin or organs.[6]
