A survey was carried out in pomegranate orchards of district Layyah, Punjab, Pakistan to explore mite fauna of that reigon. As a result of survey, a new species i.e., Hemicheyletia tanosis was recorded and described in detail here. Keywords: Hemicheyletia, new species, pomegranate, Pakistan. INTRODUCTION The mites belonging to the genus Hemicheyletia (Cheyletidae) are predatory in nature and are of great economic importance in biological control of harmful mites. This genus was erected by Volgin in 1969 and designated Paracheyletia bakeri Ehara as its type species. Summers and Price (1970) combined the three genera of Volgin to simplify the systematics of this group and provided a key for 13 species included in this genus. Later Corpuz-Raros (1972), Qayyum and Chaudhri (1979), Rasool and Chaudhri (1979b), Mathur and Mathur (1981) added 4,2,2 and 1 new species to this genus. Chaudhri and Akbar (1985) described 11 new species in this genus and made a comprehensive key for all the species of this genus. Razzaq et al (2001) described external features of H. bakeri (Ehara), found in citrus orchards of Japan. A new species of this genus has been collected from district Layyah, Punjab, Pakistan and has been described in this paper. MATERIALS AND METHODS Mite of the genus Hemicheyletia (Cheyletidae) were collected from pomegranate (Punica granatum) plants by adopting sieve collection method. In this method, different parts of plants were removed and beaten in a sieve, held over a white piece of paper. The material thus collected on the paper was examined on the spot with help of a hand lens and mites were picked up with a camel hair brush

This new species closely resembles Hemicheyletia hastatus Chaudhri and Akbar but following are points of differences in both the species: (1) In this new species, genu I and III each with 2 setae but in H. hastatus, genu I and III each with 3 setae. (2) In this new species, inner comb on palptarsus with 24 teeth but in H. hastatus, inner comb of palptarsus with 28 teeth. (3) In this new species, solenidion present on palptarsus but in H. hastatus, solenidion absent on palptarsus. (4) Length of solenidion wi on leg tarsus I is 40 urn in this species but in H. hastatus length of solenidion wi on leg tarsus I is 50 urn. (5) In this new species, length ratio: legl/iodiosoma is 0.66 but in H. hastatus, this ratio is 0.56. 54
