Two new species of the genus Tyrophagus (Acari: Acaridae)



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.
