Hewitt's red rock hare (Pronolagus saundersiae) is a species of mammal in the family Leporidae. It is a medium-sized, densely-furred rufous and brown rabbit that behaves similarly to other red rock hares, with a preference for a higher-elevation rocky habitat. Previously classified as a subspecies of Smith's red rock hare (Pronolagus rupestris), it is now regarded as its own species.

Taxonomy

Hewitt's red rock hare was named by John Hewitt (1880–1961), the director of the Albany Museum, South Africa.^[8] Hewitt originally described this taxon as a subspecies of Pronolagus crassicaudatus in his 1927 description.^[4] Its type locality was Grahamstown.^[9]^[10] He described this taxon based on skulls from Albany district, collected by Enid Saunders and Frank Bowker; the species is named after Saunders.^[11]

It was later classified as a subspecies of Pronolagus rupestris by various zoologists,^[12] including Ellerman, Morrison-Scott and Hayman,^[9] as well as Hoffman and Smith for the third edition of Mammal Species of the World .^[3]

Works which list it as its own species include the IUCN Red List,^[1] Mammals of Africa ,^[4] and Jonathan Kingdon's field guide.^[13] It is regarded as its own species due to differences in morphology (specifically having a snout bone shorter than its frontal bone, compared to Smith's red rock hare)^[14] and genetic differences in cytochrome b and 12S rRNA from other members of Pronolagus .^[15]

Fossil record

Fossils of P. saundersiae are extremely sparse. Presence of its remains in archaeological studies are mentioned in lists of taxa found at a given site, but they are never described or illustrated. It has specifically appeared in localities dating back to the Late Pleistocene, but further study is warranted to clarify its first appearance.^[16]

Description

P. saundersiae is a densely-furred, medium-sized (1.35–2.05 kilograms (3.0–4.5 lb)) red rock hare that is largely brown with light rufous underparts and a sandy- to red-colored tail. Its sides are slightly lighter than its back in coloration, and its head is grayish-brown with grayish-white cheeks.^[17]^[16]

Distribution and habitat

Hewitt's red rock hare is found in South Africa, Eswatini, and Lesotho.^[1] It specifically occurs in the South African provinces of Western Cape, Eastern Cape, Free State, and KwaZulu-Natal, as well as the western half of Eswatini and the entirety of Lesotho.^[17] Its range overlaps with that of Jameson's red rock hare in some regions, where the two species' habitats differ in elevation and rainfall,^[18] and the Natal red rock hare in others, where the two species are sympatric.^[19]

Its habitat is similar to that of other red rock hares. It occupies rocky escarpments, hillsides and kopjes,^[17] residing in particular on the tops of rocky outcroppings and in higher elevations in general.^[19] The tendency of P. saundersiae towards higher elevations in its habitat contributes to the separation of it from other red rock hares in areas of overlapping distribution.^[19]^[17] Other regions Hewitt's red rock hare are found include elevated grassland and shrubland.^[1]

Behavior and ecology

Hewitt's red rock hare is presumed to behave similarly to Smith's red rock hare - a nocturnal forager that shelters under boulders and in crevices.^[17] It is presumed to be a folivore, preferring to eat grasses, herbs and shrubs.^[20]

Known predators of Hewitt's red rock hare are Verreaux's eagle, Cape eagle-owls, and leopards, which prey upon all red rock hares.^[17]

Interactions with humans

The population of Hewitt's red rock hare was estimated to be over 10,000 mature individuals in 2004, and the species has been considered "abundant" throughout its range. However, there are several threats to the species, many of which are anthropogenic, and declines in population are anticipated.^[18]

Conservation

Hewitt's red rock hare is listed as a species of least concern by the International Union for Conservation of Nature Red List of Threatened Species; no conservation measures have been put in place, though the species does occur in at least one protected area.^[1]

Rabbits are small mammals in the family Leporidae, which is in the order Lagomorpha. They are familiar throughout the world as a wild prey animal, a domesticated form of livestock, and a pet, having a widespread effect on ecologies and cultures. The most widespread rabbit genera are Oryctolagus and Sylvilagus. The former, Oryctolagus, includes the European rabbit, Oryctolagus cuniculus, which is the ancestor of the hundreds of breeds of domestic rabbit and has been introduced on every continent except Antarctica. The latter, Sylvilagus, includes over 13 wild rabbit species, among them the cottontails and tapetis. Wild rabbits not included in Oryctolagus and Sylvilagus include several species of limited distribution, including the pygmy rabbit, volcano rabbit, and Sumatran striped rabbit.

The lagomorphs are the members of the taxonomic order Lagomorpha, of which there are two living families: the Leporidae and the Ochotonidae (pikas). There are 110 recent species of lagomorph of which 109 are extant, including ten genera of rabbits, one genus of hare and one genus of pika. The name of the order is derived from the Ancient Greek lagos + morphē.

Leporidae is the family of rabbits and hares, containing over 70 species of extant mammals in all. The Latin word Leporidae means "those that resemble lepus" (hare). Together with the pikas, the Leporidae constitute the mammalian order Lagomorpha. Leporidae differ from pikas in that they have short, furry tails and elongated ears and hind legs.

Cottontail rabbits are in the Sylvilagus genus, which is in the Leporidae family. They are found in the Americas. Most Sylvilagus species have stub tails with white undersides that show when they retreat, giving them their characteristic name. However, this feature is not present in all Sylvilagus, nor is it unique to the genus.

Jameson's red rock hare is a leporid found only on the continent of Africa, mostly in the southern portion of the continent. Zimbabwe and Namibia are thought to have the largest populations of the red rock hare and it is said to be found throughout both countries. South Africa has a population of this red rock hare but it is only found in the northwestern part of the country. Botswana also has a population in the Tswapong Hills.
