Diagnosis
ReferenceDiagnosis
P. Godefroit et al. 2013As for type and only species: A small paravian maniraptoran theropod that possesses the following osteological autapomorphies: a short snout, about 82% the length of the orbit; a lacrimal with a long posterior process participating in about half the length of the dorsal margin of the orbit and a vestigial anterior process; a short tail, composed of 20 caudal vertebrae, 2.7 times the length of the femur; chevrons reduced to small rod-like elements below the proximal 8th or 9th caudal; an ilium with a proportionally long, low and distally tapering postacetabular process (ratio ‘length/height at midlength’ = 5), and pedal unguals shorter than corresponding penultimate phalanges. The plumage of this taxon is characterized by the absence of rectrices (versus other paravians with preserved plumage) and feathers on metatarsus and pes (versus other troodontids with preserved plumage on the hindlimb).
