A revision of the genus Parastasia in the Indo-Australian region (Coleoptera: Scarabaeidae: Rutelinae)

A revision is presented of the species in the genus Parastasia. All known species are described, 11 new species are established, the parameres of most species are figured, the taxonomic levels of several taxa are changed, and 21 new synonymies are proposed. For many taxa lectotypes are designated and many specimens bearing incorrect or dubious type labels are degraded to their true status. Some aspects of distribution and dispersal are shortly discussed. A tentative key and a check list are added.
