Researchers have identified a new spider species in the Ecuadorian Amazon that closely resembles a parasitic fungus. The discovery highlights an unusual form of mimicry previously undocumented in spiders.
An international team found the spider, named Taczanowskia waska, in the Llanganates-Sangay Corridor. Field researchers initially mistook the animal for a mushroom during a nighttime survey.
The species imitates the fruiting body of fungi in the genus Gibellula, which infect spiders. It features elongated abdominal structures and pale coloring while remaining motionless on leaf undersides, where such fungi typically appear.
The find began with an observation posted on the citizen science platform iNaturalist. Scientists later confirmed it as the first known case of a spider mimicking an araneopathogenic fungus.
Nadine Dupérré of the Leibniz Institute for the Analysis of Biodiversity Change examined specimens and contributed to classifying the species. The results were published in the journal Zootaxa.
