The study herein presents brief characterization and identification key for some Acaridides (Acari: Acaridida), phoretic on termites collected from termite nests of different locations in Upper Egypt.  The present work is a continuity of the collecting activity of the first author during 1998 to 2008.  Samples were collected from certain nests of termites, Psammotermes hypostoma Desneux (New Valley, Assiut and Qena Governorates) and Amitermes desertorum (Des-neux) (Aswan Governorate).  The identification key is simple and easy to understand and the diagnosis is in most cases based on genera and species.  The two new acarid mite species, extracted from nests of the sand termite, Psammo-etermes hypostoma Desneux are described and illustrated in this study.
