Lindl. ex Meisn., Pl. Vasc. Gen.: Tab. Diagn. 387, Comm. 289. (1842) Type genus Diuris Sm. Subtribes Acianthinae Caladeniinae Cryptostylidinae Diuridinae Drakaeinae Megastylidinae Prasophyllinae Rhizanthellinae Thelymitrinae **Diurideae** is a tribe of orchid in the subfamily [Orchidoideae](/source/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] ## Infratribal classification 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](/source/Acianthinae); [Caladeniinae](/source/Caladeniinae); [Cryptostylidinae](/source/Cryptostylidinae); [Diuridinae](/source/Diuridinae); [Drakaeinae](/source/Drakaeinae); [Megastylidinae](/source/Megastylidinae); [Prasophyllinae](/source/Prasophyllinae); [Rhizanthellinae](/source/Rhizanthellinae); and [Thelymitrinae](/source/Thelymitrinae).[2] However, phylogenomic analyses have shown that [Megastylidinae](/source/Megastylidinae) is best subsumed into an expanded [Drakaeinae](/source/Drakaeinae).[1] [Rhizanthellinae](/source/Rhizanthellinae) has also been treated as a synonym of [Prasophyllinae](/source/Prasophyllinae). [2][1] ## Evolution and Ecology The tribe is estimated to have originated in the Eocene (c. 52Ma), with a crown age of c. 46 Ma. [1] The tribe is known for an unusually high number of species which engage in sexually deceptive pollination, particularly in the subtribes [Caladeniinae](/source/Caladeniinae) and [Drakaeinae](/source/Drakaeinae).[2][3] Additionally, members of the Diurideae appear to have a high degree of fungal symbiont specificity, with orchid species partnering with an average of only one to two fungal species. [1][4] ## Genera Diurideae contains about 40 accepted genera.[5] Chase et al.
