Resumen:
The record of abelisaurids in South America, particularly Argentina is relatively abundant.However, abelisaurid diversity is far from being well-known. Huincul Formation hasyielded diverse theropod remains, including the abelisaurids Ilokelesia and Skorpiovenator.The aim of the present contribution is to describe a new abelisaurid coming from the UpperSection of the Huincul Formation (Cretaceous; Cenomanian-Turonian) at the ViolanteFarm fossil site, Río Negro province, northern Patagonia, Argentina. The new taxondescribed in this contribution is represented by an incomplete specimen including wellpreservedmaxilla and dorsal vertebrae, and distorted pelvic girdle and caudal and sacralvertebrae. Its size, much smaller than large abelisaurids as Abelisaurus and Carnotaurusindicates that the new taxon probably occupied a different ecological niche within thecarnivoran guild.
