Researchers from the University of Sydney have identified new stick insect species within the Anchiale genus in Australia. Initial findings detailed the discovery of Anchiale mabiensis, an endemic species found in the critically endangered Mabi forest, and the reclassification of Anchiale robusta through genetic and anatomical analysis. Subsequent research published in ‘Austral Entomology’ expanded on these findings, revealing that what were previously thought to be two species in eastern Australia are actually five distinct species. The studies highlight the high level of biodiversity and mimicry capabilities among Australia’s approximately 130 stick insect species. A study led by researchers including postdoctoral research associate Dr. Braxton Jones utilized DNA analysis, museum specimens, and citizen science data from platforms like iNaturalist to correct decades of misidentification. The team noted that Anchiale robusta had been misidentified for a significant period, with some records involving incorrect nomenclature dating back to 1976. In addition to correcting existing classifications, the team formally described two entirely new species within the genus, one of which possesses a unique, lidlike egg structure. These identified species are distributed across Australia, ranging from northern New South Wales through coastal Queensland and into tropical northern Australia.
