The Rockstone poison dart frog (Dendrobates nubeculosus) is a species of frog in the Dendrobatidae family. It is endemic to Guyana. As it is known from only one specimen, very little information is currently available on Dendrobates nubeculosus. It has been suggested to be one of the most poorly known species in the world.

Description[]

Dendrobates nubeculosus is a small to medium-sized poison dart frog; larger than many of its contemporary Ranitomeya species, but smaller than the other members of the genus Dendrobates. The holotype specimen measures 2.5 centimetres in length, and the species' size range is unknown. It is reasonably certain that, like other members of the Dendrobates genus, Dendrobates nubeculosus females are larger than males, but even this is open to speculation. The holotype is primarily black or dark brown, with irregularly shaped blue splotches on the dorsum, and it is mottled blue and black laterally, with a solid black ventral surface. It is unclear whether, as with other Dendrobates species, Dendrobates nubeculosus is polymorphic.

Nothing is known about Dendrobates nubeculosus' social behaviour, reproductive habits, call, or toxicity. It is assumed that the breeding habits of Dendrobates nubeculosus are similar to that of its sister taxon, Dendrobates leucomelas.

Habitat[]

Dendrobates nubeculosus is only known from a single specimen collected by ornithologists in the 1980s. No precise habitat data exist but the vegetation in the area of the type locality, near Rockstone, a town on the Essequibo River, lowland jungle.
