    A FOSSIL INSECT FROM THE DWYKA SERIES OF RHODESIA
    (BERNARD PRICE INSTITUTE FOR PALAEONTOLOGICAL RESEARCH, 1974) Riek, E. F.
    Hadenlomoides dwykensis, gen. et sp. nov. (Paraplecoptera: Hadentomidael is the oldest recorded insect in the southern hemisphere. It is similar to Hadenlomum americanum from the Upper Carboniferous of North America. The close relationship between these two species tends to support the view that at least part of the Dwyka Series extends below the Permian into the Upper Carboniferous.

    UPPER TRIASSIC INSECTS FROM THE MOLTENO "FORMATION", SOUTH AFRICA.
    (BERNARD PRICE INSTITUTE FOR PALAEONTOLOGICAL RESEARCH, 1974) Riek, E. F.
    Insects are recorded from eight plant fossil localities in the Molteno "Formation", but only heavily sclerotized species (Blattodea and Coleoptera) have been obtained from six of them. A small mecopteron was found at another locality, and only at Birds River, near Dordrecht, has a more diverse fauna, with representatives of the Orthoptera, ?Mantodea, Blattodea, Homoptera and Megaloptera, been obtained. The known fauna is closely comparable with the Triassic faunas of Australia. Thirteen species, nine of which are described as new, are recorded from the Molteno. Six of the new species, and one described species, are referred to Hagla, Mesorthopteron, Triassoblatta, Dysmorphoptiloides and Ademosyne, genera represented in or previously restricted to the Australian Triassic faunas. The new monotypic genera, Prosbolomorpha (type species clara: Homoptera) and Afristella (type species delicatula: Mecoptera), are similar to genera recorded from the Triassic of Australia. Euchauliodes distinctus, gen. et sp. nov., is the earliest known Corydaloidean wing (Megaloptera); it is referred to a new family.
