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
A. Cau et al. 2017Long-necked dromaeosaurids with proximal caudal vertebrae that have horizontally oriented zygapophyses and prominent zygodiapophyseal laminae; flattened ulna with a sharp posterior margin; metacarpal III shaft transversely as thick as that of metacarpal II; ilium with a shelf-like supratrochanteric process; posterodistal surface of femoral shaft with an elongate fossa bound by a lateral crest; proximal half of metatarsal III unconstricted and markedly convex anteriorly.
A. Cau and D. Madzia 2018The clade Halszkaraptorinae is diagnosed by the fusion of the cervical ribs to centra (unknown in Hulsanpes); presence of a distinct prezygocostal lamina in proximal caudal vertebrae (unknown in Hulsanpes); horizontal orientation of the zygapophyseal facets in the proximal caudal vertebrae (unknown in Hulsanpes); abrupt reduction in size of the proximalmost caudal neural spines (unknown in Hulsanpes); presence of a prominent supratrochanteric process on ilium that is curved dorsolaterally (unknown in Hulsanpes); presence of a marked lateral ridge along the posterior margin of the distal end of the femur (unknown in Hulsanpes); unconstricted proximal end in metatarsal III (present in Hulsanpes); presence of a transversely convex dorsal surface of metatarsal III (present in Hulsanpes).
