The Rockstone poison dart frog (Dendrobates nubeculosus) is a poorly known species of dendrobatid frog endemic to Guyana. As it is known from only one specimen, very little information is currently available on D. nubeculosus.[1][2][3] It has been suggested to be one of the most poorly known species in the world.[3]
Description
D. 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, D. 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.[4] It is unclear whether, as with other Dendrobates species, D. nubeculosus is polymorphic.
Nothing is known about D. 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, D. leucomelas.
Habitat
D. nubeculosus is only known from a single specimen collected by ornithologists in the 1980s.[3][4] 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.[1][4]
