Caladenia richardsiorum, commonly known as the little dip spider orchid, Richards' spider orchid or robe spider orchid, is a plant in the orchid family Orchidaceae and is endemic to South Australia. It is a ground orchid with a single erect, hairy leaf and usually only one yellowish-green flower. It is similar to the endangered Mellblom's spider orchid (Caladenia hastata) but has a much larger leaf and the petals lack glandular tips.
