Abstract

A new species of Dendrophryniscus is described from the Atlantic Rain Forest, in the Serra dos Órgãos, State of Rio de Janeiro, Brazil, at 1050 m a.s.l. The description was based on three female specimens, with a mean snout-vent length of 23.0 mm. The new species, Dendrophryniscus organensis, differs from the eight other known species in having a characteristic dorsal color pattern, with the tips of the fingers and toes, the snout, and the sub-rostral crest reddish-orange, rostral angle accentuated, end of the snout triangular in dorsal view, and the relation of tibia and snout-vent length equals to 0.4. The large size of the oocytes suggest that the new species reproduces in bromeliads, which places the new species in the D. brevipollicatus group together with D. berthalutzae, D. carvalhoi, D. krausae, and D. stawiarskyi.
