Harajicadectes (IPA: [ˌhɑːɾɑːdʒɪkɑːˈdektes]) (meaning "Harajica biter") is a genus of stem-tetrapod from the Givetian to Frasnian Amadeus Basin in Northern Territory, Australia. The type and only species is Harajicadectes zhumini, known from 13 specimens of various preservation quality.^[1]

Choo et al., (2024) assigned a holotype and paratype to Harajicadectes, NTM P6410, and CPC 39948 respectively. The holotype consists of a partial skull and much of the body outline in dorsal view with squamation preserved. The paratype consists of a partial skull, right post-temporal and right lower jaw.^[1]

The generic name, Harajicadectes (IPA: [ˌhɑːɾɑːdʒɪkɑːˈdektes]), is derived from the member the specimens were found in, the Harajica Sandstone Member, and the Greek 'dēktēs', which translates to 'biter'. The specific name, zhumini (IPA: [ˌzjuˈmɪnaɪ]), honours Prof. Min Zhu of the Institute of Vertebrate Paleontology and Paleoanthropology, Beijing; China, for his numerous contributions to early vertebrate paleontology.^[1]

Choo et al., (2024) recovered Harajicadectes as a stem-tetrapod. They reconstructed two trees collated from 336 most parsimonious trees. The first tree is a strict consensus tree, the numbers represent Bremer support values. The second tree is a 50% majority-rule consensus tree, the numbers are node support bootstrap values.^[1] Their results are reproduced below:
