Caladenia atrovespa, commonly known as the thin-clubbed mantis orchid, is a plant in the orchid family Orchidaceae and is endemic to New South Wales. It is a terrestrial, perennial, deciduous, herb with an underground tuber and a single hairy leaf. It is similar to Caladenia tentaculata but has smaller flowers, sepals with narrower glandular tips, straight lateral sepals and a narrower labellum.[2] The species was first formally described by David Jones who gave it the name Arachnorchis atrovespa in The Orchadian from a specimen collected on Black Mountain in the Australian Capital Territory.[3] In 2010, Gary Backhouse transferred the species to Caladenia as C. atrovespa.[4] The specific epithet (atrovespa) is derived from the Latin words atra meaning "black" and vespa meaning "wasp", referring to the large black thynnid that pollinates this orchid.
