Formally described in 2008 by Novas, Pol, Canale, Porfiri, and Calvo, this taxon represents one of the largest dromaeosaurids known from the Southern Hemisphere and one of the most distinctive forms within Unenlagiinae, a group of Gondwanan paravians closely related to other South American dromaeosaurids such as \u003c\/span\u003e\u003cem\u003e\u003cspan\u003eBuitreraptor\u003c\/span\u003e\u003c\/em\u003e\u003cspan\u003e and \u003c\/span\u003e\u003cem\u003e\u003cspan\u003eUnenlagia\u003c\/span\u003e\u003c\/em\u003e\u003cspan\u003e.

Its hind limbs retained the characteristic dromaeosaurid configuration, including the sickle-shaped claw on the second toe, probably used for grasping or immobilizing prey.
