Abstract: The cheyletid predatory mite, Hemicheyletia bakeri (Ehara) habitat on the citrus plants in Ehime prefecture of Japan. Mite had an elongated body with the length of 230 ƒYm and the width of 92 ƒYm. Gnathosoma, propodosoma and hysterosoma were well differentiated. The propodosomal shield had four pairs of fanlike setae on the lateral side and two pairs on the middle portion. Opisthosomal shield possessed four pairs of fanlike setae on the corners. Anus of this mite consisted of elongated excretory pore as flap-shaped organ projected outwardly. There were three long and sharp tip setae on both sides. Legs comprised of six segments, coxa, trochanter, femur, genu, tibia and tarsus. Tarsus of leg one was longer and smoothly surfaced while, of leg two had sub segments. Tibia of the leg three and leg four had a pair of setae as other legs while tarsus of leg four was longer compared to three. Tarsus of the leg one had thick base, which was divided into two segments. Smaller segment had a pair of hook-shaped claws and several thin tenent hair. The tarsus of leg two, three and four possessed a pair of smoothly surfaced and hook-like claws. The empodial claws were elongated having pad-shaped tips. Eyes were granular-shaped projected outwardly with five regular circles and disconnected lines surrounded the eyeball. A pair of setae covers both sides of upper portion of eye.
