One-quarter of freshwater fauna threatened with extinction.

Freshwater ecosystems are highly biodiverse and important for livelihoods and economic development, but are under substantial stress. To date, comprehensive global assessments of extinction risk have not included any speciose groups primarily living in freshwaters. Consequently, data from predominantly terrestrial tetrapods are used to guide environmental policy and conservation prioritization, whereas recent proposals for target setting in freshwaters use abiotic factors.

Redescription of the goby Glossogobius tenuiformis Fowler, 1934 (Teleostei: Gobiidae) and assignment of Oman Glossogobius populations: a morpho-molecular approach.

Glossogobius giuris was originally described as Gobius giuris from the Ganges River, India. However, based on the uncertainty of its type locality and its apparent widespread distribution, a comprehensive study is being carried out to define the correct taxonomic status of this taxon. The South African population of the Glossogobius from St.

A review of the gobiid fish genus Aulopareia (Gobiidae: Gobiinae) with description of a new species from Kuwait and discussion of the status of Gobius cyanomos Bleeker.

The tropical Indo-west Pacific gobiid fish genus Aulopareia Bleeker is reviewed, with all recognised species redescribed herein, apart from one uncertain species. Additionally, a new species from Kuwait is described (A. vadosa n.

A revision of the gobiid fish genus Pseudogobius/ (Teleostei, Gobiidae, Tridentigerinae), with description of seven new species from Australia and South-east Asia.

The tridentigerine genus Pseudogobius is widespread, from temperate to tropical areas of the Indo-west Pacific. A morphological review of the genus was carried out, with the initial focus on South-east Asian and Australian species. There are about 21 nominal species in the genus; however, the type specimens for some nominal species are missing.

The correct name for Oxyurichthys longicauda Steindachner and a few other errors.

In 2015, Pezold and Larson published a revision of the gobiid genus Oxyurichthys, and made an error in their use of the name O. uronema (Weber) for one of the species. The reasons for this would make a fine example of one of Evenhuis' taxonomic impediments to nirvana (2007).

A revision of the fish genus Oxyurichthys (Gobioidei: Gobiidae) with descriptions of four new species.

The widespread tropical gobionelline fish genus Oxyurichthys is monophyletic due to its species sharing two characters considered derived within the Stenogobius Group of the Gobionellinae (Gobioidei: Gobiidae), a transversely broadened (spatulate) third neural spine that is usually bifid, and no preopercular cephalic lateralis canal. It is most closely related to Oligolepis, also of the Indo-west Pacific, and Ctenogobius, an Atlantic-eastern Pacific genus. Sixteen valid species of Oxyurichthys are redescribed and illustrated and four new species are described, O.

An annotated checklist of the fishes of the Northern Territory, Australia.

There are 1474 fish species now known from the Northern Territory, in 195 families, with a number of these species still undescribed. The 1474 species include 120 new records for the NT and three for Australia, while nine non-native species exist as small feral populations.The most speciose family is the Gobiidae (gobies), with 150 recognised species, and is the main fish group inhabiting coral reef and mangrove areas.

A new species of the blind cave gudgeon Milyeringa (Pisces: Gobioidei, Eleotridae) from Barrow Island, Western Australia, with a redescription of M. veritas Whitley.

A new species of the eyeless eleotrid genus Milyeringa is described from wells sunk on Barrow Island, Western Australia. Milyeringa justitia n. sp.

A new species of mudskipper, Periophthalmus takita (Teleostei: Gobiidae: Oxudercinae), from Australia, with a key to the genus.

A new species of mudskipper (Gobiidae: Oxudercinae) from northern Australia is described. This species was previously misidentified as P. takita [corrected] Eggert, 1935 .
