Distribution of the genus Dendrocephalus (Crustacea, Branchiopoda, Anostraca) in Argentina: a review.

The fairy shrimp Dendrocephalus brasiliensis was first found in Brazil in temporary rainpools in the northeastern states of Piauí and Bahia. Gradually, new records were added in other northeastern states up to the state of Minas Gerais, in the Southeast region of the country. The species was even found south of Minas Gerais in the state of São Paulo, but not in wild conditions, but in rearing tanks associated with aquaculture practices.

A new fairy shrimp, Branchinecta piurae sp. nov. (Branchiopoda: Anostraca), from Peru.

South American species of Branchinecta that inhabit high altitude biotopes are so far represented by B. brushi and B. papillata.

A new species of Archaebranchinecta (Anostraca: Branchinectidae) from the South American Altiplano.

A detailed morphological comparison was carried out among specimens of several samples of Archaebranchinecta Rogers Coronel, 2011 from the Altiplano of Peru, Bolivia, and Argentina. Surprisingly, striking differences were found between Peruvian samples collected near the western shore of Lake Titicaca, and those from Bolivia taken southwardly, near the east coasts of River Desaguadero and Lake Poopó. Accordingly, the new species Archaebranchinecta aimara sp.

Branchinecta uruguayensis Rogers Racz Lorenz, 2015 is a junior synonym of B. achalensis César, 1985 (Branchiopoda: Anostraca: Branchinectidae).

As part of preparation for identification keys to the branchiopod crustaceans of the Neotropical Region, we re-examined many species of Anostraca that appeared to be closely related. Our examination caused us to re-evaluate the status and relationship of two branchinectid species.

Thamnocephalus chacosaltensis, a new species of Anostraca (Crustacea: Branchiopoda) from Salta province (Argentina).
