Several species of Rubidgea has been described but they all turn out to be synonym or transferred to a different genus (ex: Broomicephalus), with only R. atrox remaining valid. However, in a 2007 study, E. Gebauer transferred the genera Dinogorgon and Tigrisaurus to Rubidgea, adding two new species, R. quinquemolaris (described on the Dinogorgon page) and R. pricei.
