چکیده

The aim of this study is to describe a new species of the costata-group from Brazil. Alona margipluma sp. nov. shares morphological traits with A. costata Sars, 1862, A. natalensis Sinev, 2008, and A. cheni Sinev, 1999, but differs from them in: (i) thin setulae between the marginal setae on the valves, (ii) setae 4-5 on the exopodite of limb III long and different in length, (iii) bottle-shaped sensillum on the basal endite of limb IV. For identification of Alona margipluma sp. nov. it is necessary to check carefully the main head pores and postabdomen characters since the former superficially resemble A. iheringula, A. setigera and Alona guttata.

A new species of anomopod related to Alona quadrangularis (Cladocera: Anomopoda: Chydoridae) is described from streams in South Vietnam. Alona kotovi sp. nov. differs from the other species of Alona s. str. (the quadrangularis-group) by the morphology of its postabdomen, labrum and thoracic limbs. The presence of a short spine at the end of the male postabdominal claw is unique to the new speci...

Knowledge of reproductive rates and life cycle of the Cladocera species is essential for population dynamic studies, secondary production and food webs, as well as the management and preservation of aquatic ecosystems. The present study aimed to understand the life cycle and growth of Alona iheringula Kotov & Sinev, 2004 (Crustacea, Anomopoda, Chydoridae), a Neotropical species, as well as its ...

Redescription of Coronatella poppei (Richard, 1897) (Crustacea, Branchiopoda, Chydoridae) and a revision of the genus in Brazil, with descriptions of new taxa.

The description of the genus Coronatella Dybowski & Grochowski, 1894 (Cladocera: Chydoridae: Aloninae) pointed towards the need for a revision of species on a worldwide scale. For the Neotropical region, the main challenge noted was the redescription of Coronatella poppei (Richard, 1897). We redescribed this species and revised populations from Brazil that had previously been assumed to be Alon...

Revision of the pulchella-group of Alona s. lato leads to its translocation to Ovalona Van Damme et Dumont, 2008 (Branchiopoda: Anomopoda: Chydoridae).

The pulchella-group of Alona s.l. (Cladocera: Anomopoda: Chydoridae) is transferred to Ovalona Van Damme et Dumont, 2008, and an emended diagnosis is provided. Ovalona meridionalis (Sinev, 2006) is removed from Ovalona due to differences in thoracic limb morphology. At the moment, Ovalona consists of 17 species, and is the largest natural genus of Aloninae. A key for the world fauna and diagnos...
