The small libellulid genus Rhodothemis is restricted to Asia and Australia. Two of the four included species were described relatively recently by Lohmann (1984) but much previously documented material was never re-identified and the distribution of species in the Indospecies in the Indo-Australian Archipelago remained poorly known. All material available in the Naturalis Biodiversity Center (RMNH) from the eastern part of the Indo-Australian Archipelago was studied and is here brought on record. Key characters are illustrated and SEM images of the genital ligula are presented.
The Afrotropical Rhyssinae are reviewed. A total of 12 species are reported from the region, including five new species: Epirhyssa brianfisheri sp. nov., E. gavinbroadi sp. nov., E. shaka sp. nov., E. villemantae sp. nov. and E. tombeaodiba sp. nov. The generic status of E. brianfisheri sp. nov. is discussed since this species could also be considered to be an extra-limital Triancyra species, emphasizing the putative paraphyletic status of Epirhyssa. Epirhyssa ghesquierei Seyrig, 1937, E. overlaeti Seyrig, 1937 and E. uelensis Benoit, 1951 are newly reported from Cameroon. We provide illustrated diagnoses and identification notes. Finally, we discuss the apparent scarcity of African rhyssines compared to other regions.
