The mites were extracted by Berlese funnel and cleared in Lactophenol, then were mounted in Hoyer’s medium on microscopic slides. Totally, 9 species belonging to two genera were collected and identified. Among identified specimens, four species are new records for Fars Province mite fauna that marked by an asterisk. The identification of two species is in the process of action. The species are listed as fallows:1- Glyptholaspis. confusa (Foa, 1900); 2- G. sp. 3- Macrocheles. merdarius (Berlese, 1889); 4- M. subbadius (Berlese, 1904); 5-M. peniculatus* (Berlese, 1918); 6- M. muscaedomesticae* (Scopoli, 1772); 7- M. glaber* (Muller, 1860); 8- M. perglaber* (Filipponi & Pegazzano, 1962); 9- M.. sp.1; 10- M. sp. 2; 11- M. sp.3.
