Identification Key for some Acarid Mites (Acari: ) Extracted from Termite Nests with Description of Two New Species Fakeer, M.1; S. A. Eraky2; M. A. I. Ahmed2 and A. S.

Abstract: The study herein presents brief characterizations and an identification key for some acarid mites collected from the nests of sand termite, Psammotermes hypostoma Desneux (Isoptera), in addition to the description of two Acaridae species. Samples (termite nests) were collected monthly from western desert (30 km North of El- Kharga city/ New Valley Governorate/ Egypt). Mites inhabiting termite nests were isolated and identified. The identification key for the Acaridae species is simple and easy to understand and the diagnosis is in most cases based on genera and species. The results of taxonomic examination concerning the Acaridae mites living in termite nests are given. Two new acarid mite species are described and illustrated hereunder.
