Two new species of Tyrophagus Oudemans, 1924, are described. One species, T. Savasi, has been discovered in several habitats of economic importance. It closely resembles T putrescentiae (Schrank) and T. neiswander Johnston & Bruce. The second, T. rebertsonae, has so far been discovered in only two, soil and tree bark. It differs from other species of Tyrophagus by a number of character. Both new species have pigmented ‘eyespots’ on the prodorsal shield. A new character used to differentiate these species is the shape of the sclerotized neck of receptaculum semins.
The position of the new species in three commonly used keys to adults of the genus Tyrophagus is indicated
