Macrocheles caelatus Walter & Krantz (1986) : 283 . Berlese described the species based on specimens collected in East Africa. Walter & Krantz (1986) redescribed this species based on specimens associated with Copris Geoffroy and Onitis Fabricius collected in Zaire and Rwanda , and also presented a key for five complex species for Macrocheles glaber group and placed M. caelatus in limue complex based on the narrow “linea angulata". Diagnosis Dorsal shield setae j1 , j4 and z4 pilose distally, J5 pectinate, Z4 , Z5 and S5 finely barbed in half distal length, other setae smooth; ventrianal shield wider than long; details of sternal shield as Figure 1 ; other diagnostic characters as Walter & Krantz (1986) . Measurements of morphological attributes presented in Table 1 . Figure 1. Macrocheles caelatus Berlese (female) – Ventral aspect of body. FIRST RECORD OF MACROCHELES CAELATUS FROM IRAN Table 1.
