Abstract
Seven species of phoretic mites were collected from museum specimens of Xylocopa latipes from Indonesia: Dinogamasus perkinsi, Hypoaspis greeni, Cheletophyes apicola, Tarsonemus platynopodae, Sennertia hipposiderus, S. koptothorsomae and Horstia helenae. In addition to the abdominal acarinarium housing D. perkinsi and other species, this and certain other palaeotropical Xylocopa species possess a pair of acarinaria formed by invaginations of the lateral mesoscutum and mesoscutellum. In X. latipes, these acarinaria housed only C. apicola. The evolutionary ecology of this community is discussed.
