The results of studies on the Ephemeroptera (mayflies) of Sri Lanka and southern India are reported. / The species of the genus Povilla are reviewed and a new subgenus, Lanquidipes, is established. Five new species, P. (P.) andamanensis, P. (P.) heardi, P (P.) junki, P. (P.) ulmeri, and P. (L.) taprobanes, are described from the Oriental Region. Keys to the adults and nymphs of Povilla are included. / Two new species of Ephemera (E. hasalakensis and E. lankensis) are described from Sri Lanka, Ephemera supposita Eaton is redescribed, and the only described member of the Potamanthidae in Sri Lanka, Rhoenanthus posticus Banks, is transferred to Ephemera and redescribed. A key to the imagos of Ephemera from Sri Lanka is included. Two new species of Ephemera, E. distincta and E. nathani, are described from South India. / The systematics of Kimminsula and related genera from Sri Lanka are reviewed. Three new genera, Wijesinhe, Belihuloya, and Lankaella, are established. Four new species, K. podi, K. indrakanthiae, L. eka, and L. deka, are described. Three other species, K. taprobanes (=K. annulata), K. fasciata, and W. femoralis are redescribed. The related new species Petersula nathani is described from South India. These genera belong to the Atalophlebioides phylogenetic lineage. / A systematic account of the Ephemeroptera of Sri Lanka is given, along with an account of their ecology, both in general and at the generic level. The biogeographic origins of the Sri Lankan mayfly fauna are discussed at the generic level. / A systematic catalog of the Ephemeroptera of the Indian Subregion is given. The species are listed, along with their synonyms and information on type-specimens. Literature citations to references to the species are given along with an indication of the stage described or illustrated. The type-specimens of mayflies in the collections of the Zoological Survey of India are discussed. / Source: Dissertation Abstracts International, Volume: 45-04, Section: B, page: 1108. / Thesis (Ph.D.)--The Florida State University, 1984.
