Taxonomy and naming

Chiloglottis platyptera was first formally described in 1991 by David Jones from a specimen collected in Barrington Tops National Park and the description was published in Australian Orchid Research.

Distribution and habitat

The winged ant orchid grows with grass in tall forest and on the edges of rainforest between Dungog and Yarrowitch, including in the Barrington Tops, Oxley Wild Rivers and Ben Halls Gap National Parks.

Conservation

Chiloglottis platyptera is listed as "vulnerable" under the New South Wales Government Biodiversity Conservation Act 2016. The main threats to the species are grazing by domestic stock, weed invasion (especially by scotch broom), the activities of feral pigs and land clearing.
