Taxonomy and naming

Diuris systena was first formally described in 2012 by David Jones and Lachlan Copeland in The Orchadian, from a specimen collected by Copeland near Ebor in 2006.[1][3] The specific epithet (systena) means "tapering to a point", referring to the tip of the labellum mid-lobe.[2]

Distribution and habitat

New England golden moths mostly grows around the edges of swamps and in soils derived from basalt near Ebor and from granite in the Cathedral Rock National Park on the Northern Tablelands of northern Ne South Wales.[1][2]
