Studies also included description of the four new predacious mites (Protogamasellopsis aegypticus, Proprioseiopsis aegypticus, Proprioseiopsis guajavus and Proprioseiopsis damiettansis), two firstly record in Egypt (Protogamasellopsis corticalis and Gamasholaspis gamasoides) and re-description of immature stages, adult female and male of the common predacious mite Protogamasolopsis denticuspredatory mites ER -
