Red rock hare

The red rock hares are the four species in the genus Pronolagus.[3][4] They are African lagomorphs of the family Leporidae.

P. melanurus (Rüppell, 1834) (Now a synonym of P. rupestris[4])

[13]

P. ruddi Thomas & Schwann, 1905 (Now a synonym[4] or subspecies[3][1] of P. crassicaudatus)

[7]

†P. intermedius Jameson, 1909

[14]

P. whitei Roberts, 1938 (Now a synonym[4] or subspecies[3][1] of P. randensis)

[15]

P. caucinus Thomas, 1929 (Now a synonym[4] or subspecies[3][1] of P. randensis)

[16]

P. barretti Roberts, 1949 (Now a synonym of P. saundersiae[4][3])

[17]

Description[edit]

Some characteristics of animals in this genus include: the lack of an interparietal bone in adults, a mesopterygoid space which is narrower than the minimal length of the hard palate, short ears (63–106 millimetres (2+1⁄2–4+1⁄4 inches)), and the lack of a stripe along its jaw.[19]

Fossils[edit]

A fossil skull of an animal in this genus was found in South Africa; Henry Lyster Jameson named the species Pronolagus intermedius[a] as it was described as being intermediate between P. crassiacaudatus and P. ruddi.[14]

Genetics[edit]

All species in this genus have 21 pairs of chromosomes (2n = 42).[19][4] The karotype for P. rupestris has been published.[20][21] The Pronolagus chromosomes have undergone four fusions and one fission from the Lagomorpha ancestral state (2n=48), which resembled the karotype of Lepus.[22]
