ABSTRACT

The mayflies (Ephemeroptera) of New Zealand in the Leptophlebiidae (Atalophlebiinae) are revised. A new family diagnosis is provided. Short descriptions are provided for genera and species previously revised by us, and full descriptions are given for 14 species, including 8 new species, and 2 new genera. The fauna now comprises 30 species in 12 genera. A new genus, Tepakia, is established for a new species, T. caligata, in a phyletic lineage previously unknown from New Zealand and related to genera in Madagascar and the Seychelles. A new genus and combination, Austronella planulata, are provided to accommodate an ephemerellid-like species previously assigned to Zephlebia. All life stages are associated and described for species of Deleatidium, which is divided into two subgenera. Deleatidium sensu stricto contains eight species, of which D. angustum and D. magnum are new. Penniketellum is reduced to a subgenus within Deleatidium and a new species, D. (P.) cornutum, is described. Mauiulus aquilus n.sp. is described. The previous subdivision of Zephlebia into two subgenera is revoked, and three new species - Zephlebia nebulosa, Z. pirongia, and Z. tuberculata - are described. The relationships of all genera and species are discussed, keys are provided for imagos and nymphs, and diagnostic taxonomic characters are illustrated.
