A New Species

Branchinecta fueguina, a new species of fairy shrimp, was found together with B. granulosa in a temporary pond beside Laguna de los Cisnes, 53°47'12''S, 67°46'55''W, Tierra del Fuego, Antártida e Islas del Atlántico Sur Province (Argentina). The male second antennal basal article has a proximal, anteriomedial auriculate welt, covered with sensory setae and a hanging posteriomedial ornamented apophysis bending abruptly anteriorly with a rounded apex. Distally, the basal article has a longitudinal medial crest, proximally produced into a blunt posteriomedially directed point. The distal article is strongly rotated, articulating almost perpendicular to the basal article. The anterior surface of the article is triangular, from its proximal joint to the broadly explanate apex. Distally, the broadened article bends anteriorly forming a complex three-lobed apex. The peculiar joint with the basal article and the distal article shape are unique in the genus.

A New Species

The name Salicornia cuscoensis given to a plant from high Andean saltmarshes near Cusco [Cuzco] and Ayacucho, Peru (South America) is validated by a diagnosis and description. The main morphological characters that separate S. cuscoensis from other closely related species are creeping habit, delicate branches, inflorescence of short and thin spikes, and seed indumentum. The new species clearly differs from other perennial Salicornia taxa growing in high Andean saltmarshes such as S. pulvinata and S. andina. The former forms small compact cushions producing very short, few-flowered inflorescences. The latter shows woody stems and forms larger rounded carpets. Morphologically, S. cuscoensis is also similar to S. magellanica, a species growing along the seashore in southern Patagonia and Tierra del Fuego, but the latter has shorter and wider inflorescences and larger seeds with a different type and arrangement of indumentum. Molecular analyses also supported the separation of S. cuscoensis. Data on habitat, distribution and phylogenetic relationships are presented for the new species and its relatives, and an identification key is given for the South American taxa of the genus Salicornia.

A new species of stephid calanoids copepodStephos grieveaesp. nov. was collected from an anchialine cave on Mljet Island (Croatia). The new species can be distinguished from otherStephosspp. by a combination of the following features: last pedigerous somite slightly asymmetrical, female genital double-somite symmetrical in ventral view, about as long as wide, single operculum; antennules of both sexes are symmetrical, 24-segmented and very long, reaching almost to end of anal somite; antennal exopod 7-segmented; maxillule displays 13 armature elements on praecoxal arthrite; female fifth legs symmetrical, uniramous and 3-segmented, terminal segment very long armed with spinules distally along inner and outer margins, single small spine on anterior surface and spiniform process laterally; male fifth legs are uniramous and asymmetrically, right leg 4-segmented and left 5-segmented, segment 4 not swollen and segment 5 simple, crescent shaped and is connected to segment 4 at approximately one quarter of its length. The shorter part of segment 5 tapers into a heavy process, while the longer part forms a club-shaped, curved extension.

A New Species

A new species of Ferorhinella Carvalho & Webb 2004 from southeastern Brazil is described and illustrated, and a taxonomic key to species in the genus is provided. Ferorhinella itatiaiensis sp. nov. can be distinguished from other known species of the genus mainly by the paramere with rounded apex and two subapical lateral spines on outer surface, one long, dorsally inserted and the other one small, ventrally inserted; and dorsal margin of the subgenital plates with a rectangular elevation, covered with small, tooth-like spines.

A New Species

Dendrocephalus carajaensis, a new species of fairy shrimp, is described from a single temporary pool in canga deposits on theSerra Sul plateau, Serra dos Carajás region in Brazilian Amazonian forest, Pará State, Brasil. D. carajaensis sp. nov. males arereadily separated from all other Dendrocephalus species except D. brasiliensis and D. spartaenovae by the absence of a spineon the posterioventral surface of the compound eye. This species is separated from D. brasiliensis and D. spartaenovae by theform of the proximal portion of the frontal appendage and the endopodites of the first three thoracopods. This species appears to be endemic to the Serra dos Carajás.

Branchinecta ferrolimneta, a new species of fairy shrimp, is described from shallow temporary pools from west of Nova Lima, about 10 km south-southeast of Belo Horizonte, in southeastern Brasil. This new species is the second species of Branchinecta to be described from Brasil. B. ferrolimneta is unique among Branchinecta species in the form of the male second antenna, and the female brood pouch and dorsolateral ornamentation.  Observations on the ecology of B. ferrolimneta are discussed.

It is morphologically similar to B. psychoon and B. levinei, but differs from them by having longer scapes, smaller flowers, sepals subequal in length, ovate dorsal sepal with obtuse apex, obliquely triangular-ovate lateral sepals with acute apex, ovate petals with entire margins and rounded apex.

A New Species

Odontella rapoporti sp. nov., from Tierra del Fuego is described, as the third species of the Odontella lobata group, which has a subantarctic distribution. The new species is similar to O. lobata and O. setosa, but can be distinguished from them by the number of chaetae on the dens (6 or 7 chaetae in O. setosa vs. 5 chaetae in the other species) and the number of chaetae in the distal whorl of the tibiotarsus (9 chaetae in O. lobata vs. 11 in the other species). The closely related monotypic genus Afrodontella Deharveng, 1981, and its type species (A. septemlobata) are described.
