Diagnosis of genus (as for the type species)
Midium-sized theropod, distinguished by the following autapomorphies: quadrate having very reduced lateral condyle and border of articular surface formed entirely from medial condyle; cervical vertebrae having poorly-defined diapo-postzygapophysal laminae; caudal dorsal vertebrae with infraparapophysial laminae concave ventrally, parapophysis oriented ventrally; caudal dorsal vertebrae in central third of tail with distally expanded transverse processes bearing cranially and distally projecting processes; distal edge of caudal transverse processes slightly concave in midpart.
