       Rubidgea is a genus of gorgonopsid that is known to have lived in South Africa during the Wuchiapingian stage of the Permian.‭ ‬Gorgonopsids are noted for having large canine teeth that projected down from the upper jaw,‭ ‬but Rubidgea seems to have had particularly large canine teeth when compared to other gorgonopsids.‭ ‬These teeth were likely the primary weapons for biting through the tough hides of prey animals to deliver devastating bites.
       In the past Rubidgea was treated as something of a wastebasket taxon with numerous species assigned to the genus.‭ ‬Later study however has now come to the conclusion that only the type species of Rubidgea,‭ ‬R.‭ ‬atrox,‭ ‬is valid,‭ ‬with other species being synonymous with either this type species or other genera.‭ ‬A PHD thesis by Gebauer in‭ ‬2007‭ ‬came to the opinion that the genus Tigrisaurus,‭ ‬and a species of Dinogorgon‭ (‬D.‭ ‬quinquemolaris‭) ‬should be transferred to Rubidgea as synonyms.‭ ‬However at the time of writing‭ (‬2014‭)‬,‭ ‬Dinogorgon quinquemolaris is still commonly treated as a valid species,‭ ‬while Tigrisaurus has been reclassified as a species of Dinogorgon,‭ ‬D.‭ ‬pricei.
