Plecoptera is an order of insects, commonly known as stoneflies. Some 3,500 species are described worldwide, with new species still being discovered. Stoneflies are found worldwide, except Antarctica. Stoneflies are believed to be one of the most primitive groups of Neoptera, with close relatives identified from the Carboniferous and Lower Permian geological periods, while true stoneflies are known from fossils only a bit younger. Their modern diversity, however, apparently is of Mesozoic origin.

Alloperla is a genus of stoneflies in family Chloroperlidae. It contains the following species:
Eusthenia nothofagi is a species of stonefly in the family Eustheniidae. It is endemic to Australia, where its range is restricted to Victoria. It is known only from the Otway Ranges and its common name is the Otway stonefly.

The Nemouridae are a family of stoneflies containing more than 700 described species, occurring primarily in the Holarctic region. Members of this family are commonly known as spring stoneflies or brown stoneflies. Fly fishermen often refer to these insects as tiny winter blacks.
The Cachar wedge-billed babbler or chevron-breasted babbler is a species of bird in the Old World babbler family (Timaliidae). It is named for the Cachar Hills in southern Assam.
Chloroperlidae are a family of stoneflies, commonly known as green stoneflies, with more than 200 species and 22 genera. They appear green to yellow in colour, and are popularly used among fisherman as bait for trout fishing. Green stoneflies live in the benthic zone of the cold streams and rivers of five continents and four zoogeographical regions, emerging from the water to live in the riparian zone as adults. They are sensitive to pollutants, making them an indicator species for determining the quality of water bodies. Chloroperlidae are hemimetabolous, having no pupal stage, but instead hatch from eggs as nymphs and mature directly into adults. They are omnivorous, feeding on small organisms and plant particles, and become more carnivorous as they mature. The classification of Chloroperlidae is contested, with some believing that they should be considered as members of different orders, as opposed to the order Plecoptera that they currently belong to.
Pseudambassis roberti is a species of fish in the family Ambassidae, the Asiatic glassfishes. It is sole species in the genus. It is endemic to Burma. The Catalog of Fishes classifies this species as Parambassis robertsi. The specific name honours the American ichthyologist Tyson R. Roberts.
