Trichomycete gut fungi in New Zealand aquatic insect larvae

摘要

New Zealand, like other regions of the world, has now been shown to have a diverse and rich assortment of Trichomycetes (Zygomycotina). Seven of the 14 species of Harpellales we found in aquatic insect larvae are known from other land areas. The remaining seven species, consisting of six Harpellales and one Amoebidiales, are new and possibly endemic. A new genus,Austrosmittium, from Chironomidae larvae is established, with two species,A. kiwiorumandA. norinsulare. The other new species areGlotzia plecopterorum(in Plecoptera),Paramoebidium bibrachium(Amoebidiales, in Ephemeroptera),Pennella asymmetrica(in Simuliidae), andSmittium rarumandStachylina minima(in Chironomidae). All of the new species were found either on North Island or South Island, but not both. We also report the presence on South Island of two widespread species of marine trichomycetes (Eccrinales),Enteromyces callianassaeandTaeniella carcini, in anomuran and brachyuran crustaceans.
