Two new species of Hypsibiidae are described with figures. Hypsibius shaanxiensis, new species, is similar to H. septulatus Pilato, Binda, Napolitano & Moncada, 2004, but differs in lacking the septulum. Mixibius tibetanus, new species, differs from other species of Mixibius by possessing three macroplacoids and cuticular bars near the base of the internal claws on the first three pair of legs.
