Description: Cape Provincial Museum, Albany Museum, Grahamstown, Natural History. Volume 19. Part 9. 20th September 1997. Stapled wraps, p387-p437. illustrated. 184mm wide x 240mm high. New unread copy. Teloganodidae stat. nov. is recognised at family rank and shown to be a sister group to Ephemerellidae. Cladistic analysis of monophyletic species groups was performed and the most parsimonius cladogram presented and discussed in terms of evolutionary trends and instances of homoplasy. There are two major clades; these are recognised as the subfamilies Austremerellinae: Austremerella subfam. nov. and Teloganodinae. Genera are defined cladistically by autapomorphies, and sequencing conventions within the context of a strictly phlogenetic classification allow their recognition at this rank. Two genera are recognised in the Austremerellinae: Austremerella from Australia and Vietnamella from southeastern Asia. Six genera are recognised in the Teloganodinae: Ephemerellina, Nadinella gen. nov., Lithogloea, and Lestagella from Southern Africa, and Macafertiella and Teloganodes from southern Asia. Previous interpretations of Austremerella and Lithogloea as subgenera of Ephemerellina were based upon symplesiomorphies and are untenable. Each genus is disctinctive in both larval and adult stages, and a stage-correlated key is provided. Descriptive and geographic accounts or each higher taxon are given and known species listed. The new genus Nadinella contains two nominal species: N. crassi (Allen & Edmunds) comb. nov. and N. brincki (Demoulin) comb. nov. Australian and South African genera are shown to be archaic phylogenetic relicts with origins in Gondwanaland prior to the initial breakup of that landmass. It is hypothesised that the presence of Oriental lineages has resulted from Australasian interchange in the case of Austremerellinae, and Africa to Asia transport via the Indian subcontinent in the case of Teloganodinae.
