Two new species of the family Oribotritiidae, Mesotritia solhoyi sp. nov. from Tibet, China and Oribotritia krivolutskyi sp. nov. from Azerbaijan, are described and illustrated. Mesotritia solhoyi is distinguished from the related species by the presence of one pair of anal setae, three pairs of adanal setae, and 8-10 pairs of long genital setae; weakly fusiform head of sensilli; rostral and lamellar setae situated at the same level. Oribotritia krivolutskyi is similar to O. submolesta, but differs by different number of lateral carinae; much longer aggenital setae; longer sensilli, interlamellar and lamellar setae; shorter notogastral setae; setae ps₂ and ps₃ thick and rigid; setae ad₂ placed more close to ad₃ than to setae ad₁; slightly different shape of sensilli.
