Oligosoma aff. inconspicuum "Pallid"
Pallid Skink
Oligosoma aff. inconspicuum "Pallid"
Length: SVL up to 70 mm, with the tail being much longer than the body length.
Weight: Unknown
Description
A beautiful high-elevation relative of the cryptic skink that has recently been identified as being a distinct taxon. Dorsal surface dull brown or grey-brown, often with dark spots, speckles, and broken stripes. They may also bear a dark mid-dorsal stripe and indistinct pale brown dorsolateral stripes. Lateral surfaces bear a notched, dark brown band, which is often edged with black and bordered by pale brown-cream stripes. The ventral surface is typically bright yellow or cream-grey and blotched/speckled, with a speckled, pale cream-grey throat and chin. This species very closely resembles the cryptic skink (Oligosoma inconspicuum) but is typically duller, less shiny in appearance, found at higher elevations, and often bears more black markings.
Life expectancy
Unknown.
Distribution
Known from Southland and western Otago including Mt Cardrona, Tapuae-o-Uenuku/Hector Mountains, Coronet Peak, Mid Dome, and Mataura Range. It is possible that this species exists elsewhere.
Ecology and habitat
These skinks are diurnal and terrestrial (occasionally semi-arboreal climbing into tall shrubs). While they do sun bask, they typically do so in a cryptic manner, while hiding in dense vegetation or near the entrance to their stone retreats. Consequently, they can sometimes be difficult to observe basking. These skinks have been recorded in a variety of habitats from the lowland right up to at least 1825 m (a.s.l).
Social structure
Unknown.
Breeding biology
Poorly understood. Females produce 1-3 young annually (at least in lowland areas) in summer (January-March).
Diet
Feeds on small invertebrates and on the fruits of native shrubs, and the nectar of flowers.
Disease
Unknown.
Conservation strategy
This species is not being actively and is not formally described. However, it has been recognized as a potentially distinct taxon (Hitchmough et al. 2021). Future work will aim to resolve the taxonomic status of this species and its relationship with other members of the inconspicuum complex.
Interesting notes
Pallid skinks at very high elevations appear to be somewhat naive to predators and have exhibited limited escape responses to researchers (pers.comm. Dr. Mandy Tocher).
