Arthrochilus corinnae, commonly known as the swamp elbow orchid,[2] is a flowering plant in the orchid family (Orchidaceae) and is endemic to the northern part of Cape York in Queensland.

The callus is insect-like, about 4 mm (0.2 in) long with its central part crowded with many shiny, yellowish red hair-like glands and the tip is about 1.5 mm (0.06 in) wide with shiny black glands.

[2][3] Arthrochilus corinnae was first formally described in 2004 by David Jones from a specimen collected on Cape York.

[4] The swamp elbow orchid grows in low-lying swampy areas with Melaleuca and Pandanus species on the Cape York Peninsula.

[2][3] As with other Arthrochilus orchids, A. corinnae is pollinated by male thynnid wasps of the genus Arthrothynnus although the species involved is not known.
