Identify six types of indigenous gecko in Australia in a long-term research project

Six new native gecko species have been discovered as part of a two-decade research program by the Queensland Museum and Griffith University.

Dr. University's Paul Oliver, who is also a senior curator at the Queensland Museum, said that identifying the new species requires careful detective work.
"One reason that these common species have been undiscovered for so long is that they are very difficult to distinguish from one another," he said.

The tail tips of the creatures were analyzed to identify the genetic differences.

The story in one tail
 Although native geckos are as common as the Asian house gecko found in many homes across Australia, there are three distinct differences:

* Asian geckos "click" the famous gecko, but their Australian cousins   are much quieter
* Asian house geckos have spikes on their tails, while the six native geckos share smooth tails
* Native geckos have no claw on the first toe, while Asian geckos have claws on all toes

"Although we can't tell them apart, [other geckos] can," he said.
Where can I find the new species?
The newly discovered Australian geckos are, according to Dr. Oliver pretty common.

"They are basically scattered across northern Australia, from Broome to Brisbane," he said.
The Northern Territory is home to the Geyhra arnhemica and Gehyra chimera, which are located in rocky areas towards the top.

Gehyra gemina is widespread in the northern deserts of Western Australia and the Northern Territory, with the Geyhra chimera and Geyhra calcitectus occurring primarily in the Kimberley region.

In the northwest of Queensland is Gehyra Lauta, better known as "Ghost Gecko" for its pale appearance, and it can also be seen in the scrubland in the northeastern Northern Territory.

If you find a gecko far from people in the bush, Dr. Paul Oliver that it is probably a local gecko.
