Initial data on arboreal oribatid mites (acari, oribatida) from vietnam

Our study is based on oribatid mite materials collected from the Dipterocarpus alatus, Haldina cardifolia and Ochrocarpos siamensis tree species in the Cat Tien National Park, southern Vietnam. A list of identified taxa includes 44 species/subspecies from 31 genera and 22 families. Of these, seven species are recorded for the first time from Vietnam, and two species are recorded for the first time from the Oriental region. Sixteen species of oribatid mites were collected from tree boles, 36 species, from tree crowns. The Jaccard index, measuring faunistic similarity, was equal to 0.18 for the mite communities of both zones.
