INTRODUCTION
Thr.i, stored grain and stored product mites occupy a highly specialized bionaa, They are considered of great economic importance as they are reported to infest and. (brava stored grain and their derivatives of all kinds, bulbs, tubers awl dry fruits, etc, Food products especially cereals are infested and contaminat:c1 by these mites after a definitive period of storage. Zakhvatkin (1941) erected the genus Troupeauia and designated Tyrogly. pints novus Ouclomans, 1907 as type species, He described, 3 species, including 1 new species, on the basis of hypopi and provided a key for these species. Later, Fain (1978) redeseribed Troupecruia nova (Oademans) from Belgium. Now the authors have collected and described. 1 new species from Pakistan, thus ralkin3 a total of 4 species in this genus. Due to lack of descriptive information about one specie3, a key, similarity matrix and phenograro of only 3 species have been prepared. KEY TO SPECIES OF GENUS TROUPEAUIA (H pope)
