THE NYMPHS OF MICREREMUS BREVIPES (ACARI: ORIBATIDA) AND COMPLEMENTARY REMARKS ON THE ADULT

The nymphs of the arboricolous oribatid mite Micreremus brevipes are described in detail. Following characters are considered as specific for the juveniles of this species: 1) darker sclerotized pygidial zone, 2) no setae on genu III in all stages and 3) solenidia phi on tibiae II and IV microcephalic. A comparison with other known immatures of the family Micreremidae indicates that the present placement of Phylleremus and Phylloribatula within this family is not justified. Additionally the legs of the adults of M. brevipes are depicted and characterized for the first time, whereas the existence of porose areas on trochanter III and IV, all femora and tarsi could be demonstrated.
