Four aquatic ascomycetes are reported from freshwater habitats in Australia for the first time. Three taxa: Bombardia sp., Jahnula australiensis sp. nov., and Savoryella aquatica sp. nov, are illustrated with interference contrast light micrographs. The new fungi are described and their taxonomic placement discussed.* Part IV, Aust. Syst. Bot. 1992, 5, 407–14.

Thirty-two species of silica-scaled Chrysophyceae of the genera Spiniferomonas, Chrysosphaerella and Paraphysomonas, belonging to the Paraphysomonadaceae Preisig & Hibberd, 1983, and Mallomonas, Mallomonopsis and Synura, belonging to the Mallomonadaceae (Diesing, 1866) Preisig & Hibberd, 1983, are recognized by electron microscopy from a wide range of Australian freshwater habitats, from tropical to temperate regions, and from a range of trophic types of lake. Eleven species are reported from Australia for the first time, and three from the Southern Hemisphere for the first time. Although most of the species are of worldwide occurrence, several are as yet known only from Australia. Several highly dystrophic lakes in Tasmania are particularly rich in species numbers and in population densities.

Submerged wood was collected from Millaa Millaa Falls and the Clohesy River in north Queensland, and examined for higher fungi. In this paper Nais aquatica sp. nov., Annulatascus velatispora gen. et sp. nov. and A. bipolaris sp. nov. are described.* Part I, Aust. Syst. Bot., 5, 109–16.

During 1996–1997 a systematic sampling programme was carried out in brackish coastal lakes and lagoons and in the delta of the River Po. In six of the nine collecting locations, 12 species of Gastrotricha were identified. One species, Chaetonotus ichthydioides, is new to science; another three species, the chaetonotidans Heterolepidoderma foliatum and the macrodasyidans Dendrodasys ponticus and Turbanella cf. pontica, and one macrodasyidan genus, Paradasys (P. subterraneus), were found in Italy for the first time. The unusual morphology of some of the species identified shows that Gastrotricha colonized brackish waters from both marine and freshwater habitats.

In spite of the fact that epiphytic algae are considered an important component of freshwater ecosystems, our knowledge of their diversity and distribution is still rather poor. Taxonomic study on the composition of epiphytic algae living on submerged leaf and root tissues of macrophyte Nymphaea pubescens Willd, found at Laguna de Bay (Philippines), was conducted. In total, 21 algal taxa were identified: 10 Cyanophyceae, 6 Trebouxiophyceae, and 5 Bacillariophyceae. The taxa described in this study represent 13 orders, 16 families, 18 genera, and 21 species based on the recent combined taxonomical approach. Of these taxa, the occurrence of a rare cyanobacteria, Chroococcus schizodermaticus West, is reported for the first time in the Philippines. One species is also reported here for the first time in the Philippines, based on current taxonomic nomenclature, and this is Cyanothece aeruginosa (Nägeli) Komárek, which is based on the former name of Synechococcus aeruginosus Nägeli. These taxonomic records are considered important basal information in enriching the knowledge about the diversity and habitat distribution of cyanobacteria and microalgae in macrophytes found in freshwater habitats in the Philippines.

Submerged wood was collected from the Clohesy River in north Queensland and examined for higher fungi. In this paper Tiarosporella paludosa and Clohesyomyces aquaticus gen. et sp. nov. are described and illustrated. Clohesyomyces is compared with Diplodia, Tiarospora, Tiarosporella and Neottiosporina.* Part V, Aust. Syst. Bot., 1993, 6, 161–67.

During our ongoing investigations of freshwater fungi in Thailand, three new chaetosphaeriaceous species, Chloridium aquaticum, Chloridium aseptatum and Dictyochaeta aquatica, were found on submerged wood in freshwater habitats. To determine their placement, a phylogenetic analysis of combined LSU and ITS sequence data was performed. Chloridium aquaticum is the only species having proliferating conidiophores and holoblastic conidiogenous cell in Chloridium. A detailed description and illustrations of the taxa is provided and phylogenetic relationship between the new taxa and their relatives are compared and discussed.

Platygerris White comprises true bugs that inhabit the surface of water in moderate to fast-flowing freshwater habitats. This genus differs from Cylindrostethus Mayr and Potamobates Champion (Gerridae: Cylindrostethinae) by having a short and flattened body; the mandibular and maxillary plates fused; and the omphalium, lateral groove, and lateral evaporatorium of the scent apparatus inconspicuous. In this paper, we redescribe Platygerris, describe two new species from Colombia, and redescribe P. asymmetricus Hungerford, P. caeruleus Champion and P. depressus White. In addition, we present an updated identification key to the species of the genus. For the first time, the cuticular structure is described for the genus based on electron microscopy.

AbstractBecause the digenetic trematode fauna of Nepal is poorly known, we began to search for schistosomes in and around Chitwan National Park (CNP) of southern Nepal. Both domestic and wild Indian elephants (Elephus maximus) are present, and we found one of two dung samples from wild elephants and 1 of 22 (4.5%) dung samples from domestic elephants to be positive for schistosome eggs. The morphology of the eggs and both cox1 and 28S sequences derived from the eggs/miracidia were consistent with Bivitellobilharzia nairi, reported here for the first time from Nepal. Also, 7 of 14 faecal samples from the Asian or greater one-horned rhinoceros (Rhinoceros unicornis) contained viable eggs indistinguishable from those of B. nairi. This identification was confirmed by comparison with both cox1 and 28S sequences from B. nairi eggs/miracidia derived from Nepalese and Sri Lankan elephants. This represents the first sequence-verified identification of a schistosome from any species of rhinoceros, and the first verified occurrence of a representative of Bivitellobilharzia (a genus of ‘elephant schistosomes’) in mammals other than elephants. Our work suggests that elephants and rhinos share B. nairi in CNP, even though these two members of the ‘charismatic megafauna’ belong to unrelated mammalian families. Their shared life style of extensive contact with freshwater habitats likely plays a role, although the snail intermediate host and mode of definitive host infection for B. nairi have yet to be documented. This report also supports Bivitellobilharzia as a monophyletic group and its status as a distinct genus within Schistosomatidae.

Amphipods within the family Chiltoniidae are an abundant yet taxonomically poorly known member of Australian freshwater habitats. With only four species known from Australia, the group is inadequately defined and marked by taxonomists as difficult to identify. Recent molecular analyses of chiltoniids from mound springs in South Australia detected several distinct species, prompting a morphological revision of material from the central and southern Lake Eyre region. Clear groups defined by unique combinations of morphological characters (focusing on uropodal, coxal, male gnathopod 2, and antennal morphology) were found that closely correlated with clades found in the molecular analyses. Arabunnachiltonia n. gen. is established for A. murphyi n. sp. from Strangways Springs in South Australia. Wangiannachiltonia n. gen. is established for W. guzikae n. sp. from Davenport Springs in South Australia. The chiltoniid genera are discussed and a key is presented to the known Australian species.
