  author={Thomas A. Hegna and Eric A. Lazo-Wasem},
Abstract Branchinecta brushi is a new species of fairy shrimp described from a pool within the volcanic crater of Cerro Paniri, northern Chile. Its occurrence represents a new altitude record for anostracans (5930 m), and it shares the title for highest altitude occurrence across all of Crustacea with a cladoceran from the same pool, Boeckella palustris. Branchinecta brushi is similar to another Chilean anostracan, B. valchetana. However, B. brushi differs from B. valchetana in the detailed… 

A Redescription of Branchinecta pollicifera Harding, 1940, and Its Placement In A New Genus (Branchiopoda: Anostraca: Branchinectidae)

Specific unique gonopod and genital segment features demonstrate that B. pollicifera constitutes a new genus, Archaebranchinecta, morphologically distinct from BranchinECTa sensu stricto.

Comments and records on the large branchiopod Crustacea (Anostraca, Notostraca, Laevicaudata, Spinicaudata, Cyclestherida) of the Neotropical and Antarctic bioregions

The large branchiopod crustacean fauna of the Neotropical Bioregion are incompletely known, with scattered records for many taxa, and many new taxa discovered and described regularly.

Possible metazoan egg fossils from the Darriwilian (Middle Ordovician) of Baltoscandia

The Baltoscandian lower Palaeozoic succession is well known for the abundance, diversity and excellent preservation of various groups of microfossils, such as acritarchs, chitinozoans, scolecodonts

Molecular Evaluation of the Fairy Shrimp Family Branchinectidae (Crustacea: Anostraca) Supports Peripatric Speciation and Complex Divergence Patterns.

A molecular phylogeny for select members of the Branchinectidae is presented to better understand the distribution of morphological variation among species, and biogeographic models of speciation for the group are tested.

A checklist of Branchiopoda (Anostraca and Cladocera) of Chilean continental waters.

An annotated checklist of the Branchiopoda (Crustacea) reported from Chilean inland waters indicates that more faunistic, taxonomic and biogeographical studies of Chilean branchiopods are necessary, especially in areas with subtropical climate, Atacama desert, Southern Patagonia, and central Chilean ephemeral pools.

Morphological Diversity Displayed by High Altitude Branchinecta papillata (Anostraca) and Additional Morphological Comparisons with Branchinecta achalensis

A basal branching in the male antenna 2 distal article, only observed in one branchinectid to date, was found in the Argentinean populations of both species.

Non-congruent geographic patterns of genetic divergence across European species of Branchinecta (Anostraca: Branchinectidae)

Lack of geographic structure coupled with very low genetic distances indicates that current Iberian and Hungarian populations of B. orientalis originated from a common population stock, and that the time elapsed since their time elapsed has not been long enough to render the clades reciprocally monophyletic.

A new species of early Cambrian arthropod reconstructed from exceptionally preserved mandibles and associated small carbonaceous fossils (SCFs)

Mandibulate arthropods (myriapods, hexapods and crustaceans) account for a major component of extant animal diversity but their origins remain unclear. Here, we re‐examine the record of exceptionally

Morphologically Conservative but Physiologically Diverse: The Mode of Stasis in Anostraca (Crustacea: Branchiopoda)

Although morphologically conservative and possessing traits typical for “living fossils”, anostracan physiological abilities are closely adapted to the challenging and variable physicochemical conditions of ponds and ephemeral pools.

An unusual 100-million-year old holometabolan larva with a piercing mouth cone

A new unusual larva preserved in Burmese amber that appears beak-like, forming a distinct piercing mouth cone is reported, which is extremely rare among larval forms, restricted to those of some beetles and lacewings.



Branchinecta oterosanvicentei n. sp. (Branchiopoda: Anostraca), a new fairy shrimp from the Chihuahuan desert, with a proposal for the conservation of the Branchinectidae of Mexico

The main diagnostic characters of Branchinecta oterosanvicentei are: (1) a pulvinus covered by scales localized on the middle of the median side of the proximal article of antenna, and (2) a network of prominent cortical crests on the cyst surface.

Three new species of Branchinecta (Crustacea: Branchiopoda: Anostraca) from the Nearctic

Branchinecta lateralis, B. constricta and B. serrata, three new species of fairy shrimp, are described from central North American temporary pools and differ in the shape of the distal segment of the male second antenna and in the female pattern of dorsolateral projections.

A new species of Branchinecta (Crustacea: Branchiopoda: Anostraca) from the Argentinian Tierra del Fuego

The peculiar joint with the basal article and the distal article shape are unique in the genus Branchinecta fueguina.


A new species of a cladoceran from a crater-lake, located at 4120 m a.s.l. in the volcano Nevado de Toluca, Mexico, is described, and is distinguished mainly by a combination of features, including an incomplete moulting; the anal opening is located on the distal end of the postabdomen, which is armed with moveable lateral spines along most of its length; and with no lobe formation.

A confusing trio of Branchinecta (Crustacea: Anostraca) from the western North America with a description of a new species

Confusion exists in the literature of the 1990s among three western North American species: Branchinecta coloradensis, B. dissimilis, and a new species described here as Branchinecta oriena n. sp.

Revision of the Genus Daphniopsis Sars, 1903 (Cladocera: Daphniidae) and a Description of Daphniopsis Chilensis, New Species, from South America

  • 1986
In a comparison of Daphniopsis with other daphniid genera, the close similarity to Daphnia (but not to Simocephalus) is demonstrated using common features of external morphology, as well as limb structure.

Notes on Cladocera and Copepoda from high altitude lakes in the Mount Everest Region (Nepal)

A macrothricid also typical of high altitude lakes in the Alps was found (Macrothrix hirsuticornis) together with two cosmopolitan Chydoridae, and two hypotheses on the evolution of cuticular pigmentation in Daphnia are examined.

The geographical distribution of Triops australiensis (Crustacea: Notostraca) in Australia: a biogeoclimatic analysis

The paper considers the distribution of Triops australiensis (Branchiopoda: Notostraca) in Australia, which is a frequent inhabitant of episodically filled temporary waters and is absent from such waters in northern Australia, and suggests biogeoclimatic analysis has a powerful predictive value.

Report on a collection of cladocera and copepoda from Nepal

22 species of Cladocera and 14 species of Copepoda are reported, mainly from Kathmandu valley, Central Nepal and some from high-altitude lakes in the Khumbu area, East Nepal, and neither can, however, be named due to inadequate material.

On the presence of the genus Branchinecta Verrill, 1869 (Crustacea, Anostraca) in Yugoslavia

A detailed study of the most essential morphological characters has been carried out in Branchinecta ferox and B. orientalis and essential features are clearly ascertained which were previously unknown or were not stated with sufficient precision.
