The zigzag velvet gecko can reach a total length (including tail) of 16 cm (6.3 in).

[5] The zigzag gecko prefers wooded habitats, and has been found under the bark of deteriorating trees, but has also been recorded in areas with rubbish or buildings.

[1] A. rhombifer is usually arboreal, but sometimes seeks shelter beneath ground litter.

[3][5] The species is severely endangered, due to habitat loss from logging, and bush fires, predators such as foxes, and feral cats, and the nature of the isolation of the gecko's population, resulting in a lack of genetic variability.

[3] The New South Wales National Parks and Wildlife Service report that the species is likely to become extinct, without intervention.
