Diurideae is a tribe of orchid in the subfamily Orchidoideae. The tribe has a centre of diversity in Australia, with occasional dispersals to New Zealand, New Calendonia, Papua New Guinea, and Malesia. [1][2]
While Diurideae itself is a well-supported clade, relationships among its constituent subtribes remain equivocal, likely due to the confounding effects of incomplete lineage sorting. [1] The tribe has previously been subdivided into nine subtribes: Acianthinae; Caladeniinae; Cryptostylidinae; Diuridinae; Drakaeinae; Megastylidinae; Prasophyllinae; Rhizanthellinae; and Thelymitrinae.[2] However, phylogenomic analyses have shown that Megastylidinae is best subsumed into an expanded Drakaeinae.[1] Rhizanthellinae has also been treated as a synonym of Prasophyllinae. [2][1]
