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. kiwiorum and A. norinsulare. The other new species are Glotzia plecopterorum (in Plecoptera), Paramoebidium bibrachium (Amoebidiales, in Ephemeroptera), Pennella asymmetrica (in Simuliidae), and Smittium rarum and Stachylina 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 callianassae and Taeniella carcini, in anomuran and brachyuran crustaceans.

Trichomycetes are an ecological group of fungi and protists found inside the gut lumen of aquatic insect larvae and have been reported virtually everywhere trichomycetologists have looked for them. Trichomycetes are common in freshwater aquatic habitats, both lentic and lotic, though lentic habitats have been explored less frequently. An inventory of trichomycetes inhabiting both stream (lotic) and lake (lentic) habitats was conducted within the Halifax Regional Municipality, Nova Scotia, Canada, including one site at the interface where a stream emptied into a lake. Twenty-six species of trichomycetes were collected from both lotic and lentic sites, nine of which are new species, all isolated from midge (Chironomidae) larvae. These are as follows: Smittium adaiosporum sp. nov. R.T. William and Strongman, Smittium cryptancora sp. nov. R.T. William and Strongman , Smittium petilum sp. nov. R.T. William and Strongman, Smittium peculiare sp. nov. R.T. William and Strongman, Stachylina abundans sp. nov. R.T. William and Strongman, Stachylina extensiva sp. nov. R.T. William and Strongman, Stachylina infrequens sp. nov. R.T. William and Strongman, Stachylina somnisimilis sp. nov. R.T. William and Strongman, and Stachylina uranus sp. nov. R.T. William and Strongman. In addition, a new continental record for Smittium hecatei L.G. Valle & Santam. previously reported from Spain and new regional geographic records for Smittium minutisporum Lichtw., Siri & M.M. White and Smittium mucronatum Manier & Mathiez ex Manier are documented. In addition, 14 other trichomycetes previously reported from Atlantic Canada were recorded and these included both harpellid fungi and protists in the genus Paramoebidium. Insects from the orders Diptera, Ephemeroptera, and Plecoptera were all found to contain trichomycetes. Data on the frequency of occurrence and the habitat preference for some gut fungi are discussed.

A New Species

Primagistemus gen. nov. (Acari: Stigmaeidae) is described and its taxonomic position discussed. Adult females of this new genus are distinguished from those of Agistemus by having four pairs of setae on the propodosomal shield, by lacking postocular bodies, by having three pairs of aggenital setae and by having two setae on genu II. They are also distinguished from those of Stigmaeus by the terminal eupathidia on the palptarsus mostly fused and subterminally separated into three minute prongs, by both subcapitular setae posterolaterad of the pharynx, by having only one seta on coxa II, and by lacking endopodal shields around coxae III-IV. A new species, Primagistemus wuyiensis, from leaves of Araucaria sp. in Fujian Province of China, is described and illustrated. This new species is distinguished from the other species of the genus from New Zealand, Primagistemus loadmani (Wood) comb. nov. (transferred from Stigmaeus), by the distally truncated dorsal body setae and by setal lengths.

Arthropods containing gut fungi (Zygomycotina: Trichomycetes) were studied from 85 collecting sites in Queensland, New South Wales, Victoria, and Tasmania. The emphasis was on the fungal order Harpellales in endemic larvae or nymphs of aquatic Diptera, Ephemeroptera, and Plecoptera, but included a few Eccrinales in Crustacea. Of the more than 25 species of trichomycetes dissected from arthropods, 20 are described and illustrated. Of these, 10 are new species that are possibly endemic to Australia. All new Australian species were different from new species described in a correlated study of New Zealand trichomycetes. The new Australian species are Austrosmittium aussiorum, Glotzia tasmaniensis, Smittium aciculare, Sm. boomerangum, Sm. delicatum, Sm. paludis, Sm. rupestre, Stachylina queenslandiae, St. thaumaleidarum (Harpellales), and Parataeniella latrobi (Eccrinales). Other possible new genera and species are briefly described, but not named. Thirteen axenic cultures of Harpellales were obtained; these include one of the new species, Sm. boomerangum, and another species not previously isolated, Sm. elongatum. Some unusual insect families were found infested by Australian trichomycetes. Distribution data on these fungi and their hosts are provided.

New Zealand’s surrounding deep waters have become known as a diversity hotspot for glass sponges (Porifera: Hexactinellida) in recent years, and description and collection efforts are continuing. Here we report on eight rossellids (Hexasterophora: Lyssacinosida: Rossellidae) collected during the 2017 RV Sonne cruise SO254 by ROV Kiel 6000 as part of Project PoribacNewZ of the University of Oldenburg, Germany. The material includes six species new to science, two of which are assigned to a so far undescribed genus; we further re-describe two previously known species. The known extant rossellid diversity from the New Zealand region is thus almost doubled, from nine species in five genera to 17 species in eight genera. The specimens described here are only a small fraction of hexactinellids collected on cruise SO254. Unfortunately, the first author passed away while working on this collection, only being able to complete the nine descriptions reported here. The paper concludes with an obituary to him, the world-leading expert on glass sponge taxonomy who will be greatly missed.

This paper reports the occurrence of 11 species of freshwater bryozoans collected from the States of Pará and São Paulo, Brazil, including two new genera and four new species. Two new families are erected, Tapajosellidae n. fam. in the Class Phylactolaemata, and Natanellidae n. fam. in the Class Gymnolaemata, Order Ctenostomata. One new genus, Tapajosella n. gen., accommodates the new phylactolaemate genus and species, Tapajosella elongata n. sp. The other new genus, Natanella n. gen., includes the former ctenostome, Hislopia natans, now Natanella natans n. comb. Other new species are the phylactolaemates, Plumatella pirassununga n. sp., Plumatella jariensis n. sp., and Fredericella tenax n. sp. Additional species include the ctenostome Hislopia corderoi Mané-Garzón, 1960, and the phylactolamates Plumatella osburni (Rogick & Brown, 1942), Plumatella siolii Wiebach, 1970, Plumatella casmiana Oka, 1907, Plumatella marcusi Wiebach, 1970, and possibly Plumatella philippinensis Kraepelin, 1887. The notable expansion in diversity of freshwater bryozoans from Brazil revealed by material amassed during brief and spatially-limited collection is suggestive of considerable undiscovered diversity in this poorly studied region of the world.

A New Species

A total of 14 species in seven tingid genera have been described from the mid-Cretaceous Burmese (Kachin) amber from northern Myanmar, with very distinct paleofauna. Here, a new species of a new genus, Burmavianaida anomalocapitata gen. et sp. nov., is described from Kachin amber. This new species can be readily distinguished from the other described tingid taxa by the apparently smaller body and the structures of the pronotum and hemelytron. Burmavianaida gen. nov. shares the diagnostic characters with two clades composed of three extant subfamilies (Cantacaderinae + Tinginae) and Vianaidinae and may represent an extinct clade distinct from them. To the best of our knowledge, B. anomalocapitata sp. nov. is the smallest species of Tingidae among over 2600 described species. Our new finding supports the hypothesis of the miniaturization phenomenon of insects in Kachin amber, as suggested by previous studies.

Abstract Aim: We aimed to understand how aquatic insect larvae communities associated with bromeliad phytotelmata are affected by plant architecture, predators and resources (local factors), and by geographical distance (regional factors) in two different plant phenological phases. Bromeliad flowering results in plant structural changes, which favours insect dispersal. Considering that local and regional factors may affect the community of aquatic insect larvae, we expected that composition, beta diversity and the importance of those factors would differ in the vegetative growth and flowering phases. Methods We performed six samplings of the bromeliad associated fauna in 2010, three during the first semester - vegetative growth phase - and three during the second semester - flowering phase. In each sampling, we collected 12 plants along the rocky walls with similar location distribution, with a total of 72 bromeliads studied. Results Although beta diversity (PERMDISP) did not differ between vegetative growth and flowering, NMDS followed by ANOSIM showed that composition was significantly different in the distinct phenological phases. IndVal results showed that three Diptera morphospecies were discriminant of the vegetative growth phase. In addition, pRDA revealed differences in the relative contribution of local and regional factors to explain insect larvae community structure. During the flowering phase, local factors predominated, while during vegetative growth, regional factors were more important. Conclusion Differences in dispersal rates between the two phenological phases, likely due to adult insect pollination and further oviposition, influenced community structuring. Therefore, flowering events account for differences not only in the composition, but also in community structuring of aquatic insect larvae inhabiting the phytotelmata of Aechmea distichantha Lem. (Bromeliaceae).
