Rockstone poison dart frog
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''.〔 It has been suggested to be one of the most
poorly known species in the world.〔
== 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. 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''.
