Objective To comprehend parasitic gamasid infection on Phrynocephalus przewalskii Strauch,1876 in Taole area,Ningxia.Methods Ecological investigation on animals and insects was carried out.Results Parasitic gamasid of four species of 3 genera and 2 families were found on Phrynocephalus przewalskii,with average infection rate of gamasid of 49.23% and mean index of gamasid of 1.08.The highest individual was with 10 gamasids.Parasitic location and number of the gamasid showed as follows： hindlimbnotumaround anusforelimb or belly head and neck.Average infection rate of gamasid in hole was 25.00% with the index of gamasid of 0.47.Conclusions There are parasitic gamasids of four species on Phrynocephalus przewalskii Strauch,1876 with the most on the body surface,and wide parasitic location.The infection rate of gamasid in hole is low.
