If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.

Diagnosis
ReferenceDiagnosis
L. Salgado et al. 1997Anterior trochanter of femur absent. Anteroposterior diameter of distal end of tibia subequal/greater than distal width.
R. Allain and N. Aquesbi 2008Thus, 16 unambiguous synapomorphies diagnose this clade: the anteroposterior length of the frontal which is less than its minimum transverse breadth; a long anterior process of the quadratojugal; the presence of a quadrate fossa; a dorsoventrally expanded prearticular; the U-shaped anterior portion of the tooth rows; the reduced number of phalanges of the manual digit II; the S-shaped pubic symphysis; the reduced femoral fourth trochanter, the laterally projected tibial cnemial crest; the spreading posture of the metatarsus; the length of the metatarsal III which is less than 25% that of the tibia; the broader transversely than long proximodistally proximal pedal phalanges; the shallow or absent collateral ligament fossae on the non-ungual pedal phalanges; the rudimentary penultimate phalanges of the pedal digits II-IV; the sickle-shaped unguals of the pedal digits II-III; and the rudimentary pedal digit IV ungual.
