Seringia botak Cheek sp. nov., based on a collection made by the authors in 2017, is described from metalliferous grassland and savannah habitats in Indonesian New Guinea. Initially this appeared to be the first verified record of Seringia from SE Asia and to extend the range of the genus c. 1500 km further north than the previously recorded northern limit in Northern Territory, Australia. Further research, however, showed two previous specimens of the taxon from New Guinea, which had been overlooked. The extinction risk of Seringia botak is assessed as Endangered using the IUCN 2016 standard.
