The metazoan fauna of Antarctic and sub-Antarctic freshwaters is reviewed. Almost 400 species, notably rotifers, tardigrades and crustaceans have been identified. Sponges, molluscs, amphibians, reptiles and fishes are absent though salmonid fishes have been successfully introduced on some of the sub-Antarctic islands. Other alien introductions include insects (Chironomidae) and annelid worms (Oligochaeta). The fauna is predominately benthic in habitat and becomes increasingly depauperate at higher latitudes. Endemic species are known but only a few are widely distributed. Planktonic species are rare and only one parasitic species has been noted.

“…David G. Frey in a personal communication to Dartnall (1995) doubted the conspecifity of the Palaearctic and Subantarctic populations. Examination of populations from different regions of the southern hemisphere revealed substantial differences between them, sufficient to consider them to be a series of separate species, and also different from Palaearctic M. hirsuticornis s. str.…”

The aim of this paper is to revise populations of Macrothrix cf. hirsuticornis (Cladocera: Anomopoda: Macrothricidae) from different regions of the southern hemisphere. It is demonstrated that M. hirsuticornis Norman and Brady, 1867 s. str. is absent there, and five related species occupy different Subantarctic islands and the southernmost portions of South America, and Africa. Macrothrix boergeni Studer, 1878 from the Kerguelen Archipelago is redescribed and a neotype is selected. All populations in the southernmost portion of continental South America, Tierra del Fuego, Falklands, South Georgia, South Orkney Islands, and on the Antarctic Peninsula belong to M. oviformis Ekman, 1900. All the taxa described from this region-M. ciliata Vávra, 1900, M. odontocephala Daday, 1902, M. propinqua Sars, 1909, and, probably, M. inflata Daday, 1902are junior synonyms of M. oviformis. Two new species are established: M. sarsi sp. nov. from the Cape region of South Africa and M. ruehei sp. nov. from Crozet, Marion islands, and Île Amsterdam. Macrothrix cf. flagellata Smirnov and Timms, 1983, previously known only from Tasmania, is found on Macquarie Island too. Differences between species from the southern hemisphere and Palaearctic M. hirsuticornis are summarized. It is demonstrated that characters of the general body shape (i.e. presence of a hood or a tooth on posterior head border) have a limited value for the systematics of Macrothrix. In contrast, some fine details, mostly missed by previous authors, are valuable for species discrimination. The present study increases the number of species recorded from the Antarctic-Subantarctic region. Probably, the current pattern of Macrothrix distribution results from a disruption of a pan-continental (early Mesozoic?) species complex.

“…The diversity of rotifer in Ly Son Island was higher than that in Heard Island (17 taxa recorded) (Dartnall, 1995), but lower than that in 31 lakes in North Island, New Zealand (78 species recorded) (Duggan, 2002). However, the result shows that the number of species recorded in the islands depends on the number of lakes and samples.…”

In order to provide the information on the biodiversity of Rotifera from Ly Son Island, six samples from four water bodies from Ly Son Island, Quang Ngai Province were collected in May 2019. A total of thirty-six species-level taxa have been identified, belonging to 12 families of Rotifera phylum. Of these, the Lecanidae is the most diverse family with 14 taxa recorded (38.9%) followed by Brachionidae (6 taxa, 16,7%), and Trichoceridae (5 taxa, 13,9%). Eight families are present with only a single species, viz. Asplanchnidae, Dicranophidae, Gastropodidae, Hexathridae, Synchaetidae, Scaridiidae, Notommatidae, and Mytilinidae. Lophocharis salpina is recorded new to Vietnamese rotifer fauna.
