The family Hyaenidae is made up of two sub families, the protelinae and the hyaeninae. The protelinae is made up of one species, the aardwolf (Proteles cristatus). The hyaeninae is comprised of three extant species, the striped hyaena (Hyaena hyaena), the brown hyaena (Parahyaena brunnea), and the spotted hyaena (Crocuta crocuta).
Keys to genera, Proteles, Crocuta and Hyaena (includes Parahyaena)
Aardwolf (Proteles) has five digits on the fore foot, whereas the hyaeninae have only four. Additionally, with the exception of the canines, the aardwolf teeth are very small and pin like. Spotted hyaenas (Crocuta) have short rounded ears, and short spotted coats. Spotted hyaenas (adults) lack the upper first molar. Sexual dimorphism favours the females. Striped hyaenas and brown hyaenas (Hyaena) have long pointed ears, stripes on the legs and manes that they can erect when excited. Upper first molar present. <ref name=”Skinner”>J. Skinner and C.

Geographical distribution of protelinae
Aardwolves are found in two distinct regions of Africa. In southern Africa they are found throughout South Africa and Botswana and through most of Namibia and Zimbabwe and in parts of Angola, Zambia and Mozambique. They also occur in eastern Africa in most of Tanzania, all of Kenya and Somalia, parts of Uganda, Ethiopia, Eritrea, Dijibouti, Sudan and Egypt. [1].
