Two ornamental new species of Schismatoglottis are described and illustrated from Borneo. Schismatoglottis metallica from Kalimantan Barat, Indonesian Borneo, assigned to the Schismatoglottis Multinerva clade, and S. reticosa from the upper Engkari river in SW Sarawak, Malaysian Borneo, provisionally placed in the Petradoxa clade. Recognition of these novelties takes Schismatoglottis on Borneo to 132 species, of which 86 have been described since the year 2000.
