Slater's Skink is a smooth, heavily built burrowing skink. The upperbody is greyish brown in colour with black patterning and the underbody is pale cream to bluish-grey. It can have a rose-coloured flush around the sides of the head and neck area (G.Fyfe 2004, pers. comm.). Average snout-vent length is 8.5 cm (Horner 1991; Pavey 2002).

This Skink occurs on alluvial plains in central areas of the MacDonnell region of the Northern Territory (Horner 1991; Wilson & Swan 2003). Speciments have been collected from six localities in the Finke and MacDonnell Ranges bioregions (Pavey 2002; G.Fyfe 2004, pers. comm.).

There is an unconfirmed record from Loves Creek Pastoral Lease in the East MacDonnell Ranges in 1989 that is likely to be this species (S. McAlpin pers. comm. in Pavey 2002).

The subspecies appears to have been abundant in the 1960s, but since then numbers have declined dramatically, and the total population is now thought to be no more than 200-300 mature individuals. Extensive surveys during 1995 and 1999-2000 failed to locate any individuals at the Alice Springs, Ellery Ck and Tempe Downs localities or nearby sites, but discovered an extant population at Finke Gorge National Park (Pavey 2002). Surveys during 2004 found a new location on the Hugh River and confirmed the presence of the subspecies at the Tempe Downs, Ellery Ck and Illamurta Springs localities (G.Fyfe 2004, pers. comm.).

Egernia slateri slateri is the northern subspecies of E. slateri. The southern subspecies, Egernia slateri virgata, occurs in far northern South Australia (Horner 1991). The southern subspecies is known from only four specimens, and has not been located since 1914 (Pavey 2002).

In 1989, several specimens resembling Egernia slateri were captured in the Kimberley region of Western Australia, well out of the species' known range (Woinarski 1992). Although they have appeared in publications as Egernia slateri (e.g. Storr et al. 1999), they also resemble the closely related E. striata, and the population is not presently accepted by the Western Australian Museum as being E. slateri (Aplin & Smith 2001).

At most sites, Slater's Skink occurs in eucalypt and mulga woodland and open woodland on alluvial soils close to drainage lines. However in Finke Gorge National Park it has been located in a range of environments including an isolated dune supporting shrubland, low rolling calcareous rises with 60% spinifex cover and on an elevated, narrow, rocky creekline (Pavey 2002).

A burrowing species, it digs complex burrow systems under small trees and shrubs, particularly corkwood (Hakea divaricata), Turpentine (Eremophila sturtii) (Pavey 2002), and Spotted Emu-bush (Eremophila maculata) (G.Fyfe 2004, pers. comm.). The burrows are dug into the low pedestal of soil that usually builds up beneath these trees (Pavey 2002). May occasionally be found under ground debris (Horner 1991).

The species is diurnal (active by day) (Pavey 2002).

Feeds on arthropods (Pavey 2002).

Females give birth to live young (Pavey 2002).

The following table lists known and perceived threats to this species. Threats are based on the International Union for Conservation of Nature and Natural Resources (IUCN) threat classification version 1.1.
