The genus Ridleyandra, established by Weber & Burtt (1998a) for the species formerly placed in Didissandra sect. Speciosa Ridl. and Didissandra sect. Stilpnothrix C. B. Clarke, is revised. 23 species are recognized (the specific rank of some being still uncertain), 4 are described as new; two names are reduced to synonymy. 18 species, accommodated in sect. Ridleyandra, occur in the Malay Peninsula (3 of them in SE Thailand), 5 species (referred to sect. Stilpnothrix) in Borneo (incl. Natuna Islands).
