The harlequin orchid was first formally described in 1967 by Alick Dockrill who gave it the name Parasarcochilus hirticalcar and published the description in Australasian Sarcanthinae. [5] In 1998 Mark Clements and Benjamin John Wallace changed the name to Sarcochilus hirticalcar. [6] The specific epithet (hirticalcar) is derived from the Latin words hirtus meaning "hairy", "rough" or "shaggy" [7] :391 and calcar meaning "a spur". [7] :621
