Description
The holotype is a mature female measuring 164 mm (6.5 in) in total length and 7 mm (0.3 in) wide at mid-body. There are 207 (left side) and 214 (right side) annuli, without clear external differentiation between primary and higher-order annuli. The body is strongly dorsoventrally compressed. The head is small and pointed. The eyes are clearly visible. The preserved specimen has lilac-brown anterior part of the body, becoming paler towards the head. The darker dorsal colouration grades through lighter brown to cream-tan ventrally.[2]
Habitat and conservation
The precise location where this species was collected on the Bonaccord estate in 1987 is unknown.[1][2] It is probably similar to other members of the genus, which are oviparous, lay terrestrial eggs, and are subterranean as adults. Threats to this species are unknown.[1]
