but was shown to be a distinct species based on molecular grounds, most recently by A. Engelbrecht and colleagues in 2011. Populations within O. auratus have been shown to encompass all five cytotypes described by G. Contrafatto and colleagues in 1992. Two of these cytotypes are independently derived in populations of O. wrroratus, suggesting that chromosomal rearrangements played no role in speciation of these two sibling species. Nevertheless, according to N. Pillay and colleagues in two 1995 papers incipient speciation may be occurring due to chromosomallyinduced reproductive isolation of populations of the “Al”cytotype from high altitudes (above 1400 m) in the Drakensberg Mountains. Monotypic.

Head-body 133-202 mm, tail 58-120 mm, ear 17-5-26 mm, hindfoot 21-38 mm; weight 63-211 g. The South East African Vlei Rat is large and robust, with large blunt head,short tail, and shaggy fur. Dorsum is olive-brown to cinnamonbrown above and dark to paler gray below. Tail is short (c.60% of head-body length), darker above than below and sparsely haired. Ears are small and close to body. Upper incisors have one deep groove, and lower incisors have one deep and one shallow groove. M has four laminae, and M” has six or (very seldom) seven laminae.

|

Females are polyestrous, with 3—4 births/year. Breeding is curtailed during cold dry seasonwhen food availability is reduced. Litters have 1-5 young. Gestation is 5-6 weeks. Young are born precocial, with erupted incisors capable of nipple-clinging on their mother. Sexual maturity is attained at ten weeks for females and 14 weeks for males.

|

South East African Vlei Rats construct distinctive runways in grass. At a site near Pretoria, densities varied throughout the year from 17 ind/ha to 72 ind/ha. They are partly territorial (guarding immediate nest areas), with mean home ranges of1730 m? for males and 1252 m? for females. They are solitary and aggressive, with levels of aggression decreasing from scrotal males to perforate females to non-scrotal males to imperforate females.
