The Seychelles islands are biogeographically interesting, with ancient affinities to Africa and Asia, recent colonizing species from the Indo-Pacific and modern introductions. Until recently relatively little has been known about the biodiversity of the islands. This is changed by the series of monographs on the Seychelles fauna, presenting the latest information on all the terrestrial and freshwater animals of the islands. "The Diptera of the Seychelles Islands" includes all 630 recorded from the islands, presenting distribution records, descriptions of many species and assessments of their conservation status.
