Nephrurus amyae
The largest species of Nephrurus and reputedly the largest and heaviest gecko in Australia. Spiny tubercles crowd its reddish-brown body, and the very short tail ends in a knob.
The Centralian rough knob-tailed gecko (Nephrurus amyae) is a carphodactylid gecko endemic to central Australia. It is reddish brown, with spiny tubercles crowded especially on the rump and thighs, which distinguishes it from the other members of the Nephrurus asper species group. The tail is very short and ends in a knob. Nocturnal and living in desert and rocky country, it generally does not dig burrows and instead shelters by day in rock crevices. When threatened it gapes, raises its tail, and vibrates its body while producing sound. The epithet honours Amy Couper, daughter of the describing herpetologist. Because Australia prohibits the export of its native wildlife, only captive-bred animals are traded.

Nomenclature follows global taxonomic authority databases.
At the request of Australia, genus Nephrurus spp. has been listed on CITES Appendix III (effective June 22, 2022). Because it is on Appendix III, registration as an international rare species is not required. Australia prohibits the export of wild animals native to its territory, and specimens in trade are limited to captive-bred individuals. This species is not included in the specific animals listed in the Schedule of the Enforcement Ordinance of the Act on Welfare and Management of Animals, nor is it designated as a specified alien species under the Enforcement Ordinance of the Alien Species Law.

Carnivorous: insects, other arthropods and small reptiles
Keep the basking spot at 31-32 C, the cool side at 21-27 C and nights above 18 C, with a clear day-night difference. As a rough-skinned species it prefers the drier end of the genus: misting the top of the hide with enough water to last a day or two is sufficient. It does spend the day in rock crevices, however, so it is not tolerant of complete dryness, and a separate humid hide is sometimes provided.
It does not normally burrow, so a thin substrate is acceptable, but females dig when laying, so give them somewhere they can excavate. Build daytime retreats from rock work and terracotta hides. Being a large species it is best given an enclosure of about 90 x 45 x 45 cm. Seat rocks on the enclosure floor before adding substrate.
Carnivorous, taking insects and other arthropods as well as small reptiles. In captivity use crickets and dubia roaches as the staple, dusted with calcium and vitamin supplements. Because of its bulk, choose larger feeders than for other knob-tails.
Timid; when startled it gapes, raises and waves its tail and vibrates its body while making a barking sound. Knob-tails live solitarily, so house them individually rather than together, and keep handling to a minimum.
Listed on CITES Appendix III as Nephrurus spp. at Australia's request, effective 22 June 2022. Appendix III requires an export permit from the listing state and a certificate of origin from other states; no Japanese registration certificate is needed. Because Australia bans the export of its native wildlife, every legitimately traded animal is captive-bred. The IUCN assesses it as Least Concern.
Intermediate. This is an intermediate-level species. Some prior experience and knowledge of environmental management are recommended.
