Etymology
The specific name, hardyi, is in honor of Kiwi herpetologist Graham S. Hardy.[3]
Geographic range
In the Poor Knights Islands, O. hardyi occurs on Tawhiti Rahi Island, Aorangi Island, Aorangaia Island, Archway Island, and two rock stacks (Stack “B”, Stack “C”).[1]
Taxonomy
Oligosoma hardyi closely resembles the copper skink, Cyclodina aenea, and was considered to be a member of this species until recently when it was described as a new species using morphological, allozyme and DNA methods (Chapple et al. 2008). More recently, the genus Cyclodina was merged with the genus Oligosoma (Chapple et al. 2009), resulting in a new combination for this species, Oligosoma hardyi.
Habitat and behaviour
Description
Oligosoma hardyi can be distinguished from all other Oligosoma species, including the other members of the O. aeneum species complex, by having suboculars three and four separated by the fifth supralabial under the eye. In addition, the midbody scale count is greater than that of the slight skink (Oligosoma levidensum) from the Te Paki region.[2]
Oligosoma hardyi may attain a snout-to-vent length (SVL) of 5.5 cm (2.2 in).[1]
Diet
Oligosoma hardyi preys upon invertebrates.[1]
Reproduction
Oligosoma hardyi has been described as being viviparous[1] and as being ovoviviparous.[2]
