Researchers in Australia have discovered a new species of gecko, known as the lesser thorn-tailed gecko (Strophurus spinula), characterized by its beautiful eyes that blend with the rest of its body, allowing it to evade detection for decades. The newly identified species measures about 6.1 cm in length and features a spotted pattern of white and gray scales, which is also replicated in its eyes.
These camouflaged reptiles inhabit forest areas across southwestern Australia, although scientists are uncertain about the population size of this recently discovered species. The lesser thorn-tailed gecko (Strophurus spinula) is the 21st species recognized in the genus Strophurus, all of which are endemic to Australia. This group is collectively known as thorn-tailed geckos due to the small spines on their tails and sometimes above their eyes.
It is believed that Strophurus spinula is closely related to Strophurus assimilis. However, in a new study published in the Records of the Western Australia Museum, scientists conducted extensive genetic analysis of the newly discovered genus and found it to be a distinct species.
The researchers noted that a close examination of the lesser thorn-tailed gecko revealed that the newly discovered species can be physically distinguished from the genus Strophurus. Like all other thorn-tailed gecko species, Strophurus spinula can excrete a harmless, foul-smelling chemical from glands near its tail to deter potential predatory birds that might swoop down from overhead shrubs, where they are typically attacked.
Strophurus spinula appears to prefer woodlands dominated by Acacia aneura, known as mulga, which thrive in extremely arid conditions. Scientists are seeking to understand why the new species favors this type of habitat.
