A brand new spider discovered within the Amazon disguises itself as a parasitic fungus – much like the plot of the video game and TV series The Last of Us.
Researchers say the species, named Taczanowskia waska, is the primary known example of its kind.
It has been described by a world team of researchers, including experts from the Leibniz Institute for the Evaluation of Biodiversity Change (LIB). Their findings have been published within the scientific journal Zootaxa.
The spider was discovered within the Llanganates-Sangay Corridor, a region of Ecuador thought to be one of the vital biodiverse areas on the planet.
Researchers said the animal’s camouflage was so convincing that it was initially mistaken for a mushroom during a night-time expedition.
The spider resembles the fruiting body of a fungus from the genus Gibellula, which infects spiders and takes over their nervous system – similar to people who inspired the parasitic fungus from The Last of Us.
It has elongated structures on its abdomen and a pale surface that closely resembles fungal growth. The spider also stays motionless on the underside of leaves, the identical location where the fungus is often found.

Scientists consider this mixture of appearance and behavior has evolved to assist the spider avoid predators while also improving its probabilities of catching prey.
By mixing into its surroundings and appearing to be an unremarkable object, the spider is less more likely to be detected and may more easily ambush unsuspecting insects.
In accordance with the researchers, that is the primary documented case of a spider mimicking a parasitic fungus that infects members of its own group.
The finding offers fresh insight into the evolution of mimicry and the ecological role such adaptations can play.
The genus Taczanowskia is taken into account rare and stays poorly understood. Researchers say much of its ecology remains to be unknown because these spiders are seldom encountered within the wild.
Amongst those involved within the study was Nadine Dupérré of the Museum of Nature Hamburg at LIB, who examined reference specimens from scientific collections and helped classify the brand new species.
The invention began with an remark posted on the citizen science platform iNaturalist. Users initially debated whether the organism was a mushroom before identifying it as a spider, prompting further scientific investigation.
Researchers say the case highlights the growing importance of citizen science in biodiversity research.
‘Finds like these show the worth of scientific collections. They allow us to categorise recent species and compare them with historical specimens. Combined with international collaboration and citizen science, this opens up recent opportunities for researching biodiversity,’ explains Nadine Dupérré.
Scientists say the invention underlines each the extraordinary biodiversity of tropical ecosystems and the way much stays to be explored.
They add that it also demonstrates the importance of international collaboration and recent sources of knowledge in helping researchers higher understand global biodiversity.
