Genoplesium nigricans, commonly known as mallee midge orchid, is a species of orchid endemic to Australia. It is a terrestrial herb with a single leaf mostly surrounding the stem, and up to 50 tiny, greenish flowers with a deep maroon-coloured labellum and often have a fruity fragrance. Australian authorities use the name Corunastylis tepperi, a widespread species which has been confused with Corunastylis nigricans, a species with purplish brown flowers and which only occurs on Kangaroo Island and the Eyre Peninsula.
