A rapid assessment survey identified 39 phytophilous cladocerans species from littoral zones of rivers, permanent and temporary lagoons, and swamps of the Paranã River Valley, Goiás, Brazil, 22 are registered for the first time in Central Brazil. Aspects of the taxonomy of some of these species are discussed. Cluster analysis (UPGMA) revealed two phytophilous cladoceran assemblages, characterized by higher or lower richness and relative abundance of species of the families Daphniidae and Moinidae (filter feeders), in comparison with the dominant families Chydoridae and Macrothricidae (scraper feeders).

Three new species of Aloninae cladocera from Central and South Brazil are described. Two of them, Acroperus tupinamba sp. n. and Alona yara sp. n., were previously recorded from the area as European taxa Acroperus harpae (Baird, 1834) and Alona quadrangularis (O.F. Müller, 1776), respectively. Acroperus tupinamba differs from the other species of Acroperus in smaller size, long posterior setae of the valves, shorter and wider postabdomen, short setules near the base of postabdominal claw, long apical spines of antenna, and peculiar morphology of limb IV exopodite. Alona yara differs from A. quadrangularis and A. kolweizii Van Damme & Dumont, 2008 in the number of ventral setules on ventral face of limb I, from A. boliviana Sinev et Coronel, 2006 in the shape of the body and postabdomen, narrow labral keel, and absence of projections on epipodites IV–V. The third new species, Celsinotum candango sp.n. differs from all other species of the genus in proportions of postabdomen. It differs from Australian species (C. hypsophilum Frey, 1991, C parooensis Frey, 1991, and C. platamoides Frey, 1991) in a less developed dorsal keel, lateral head pores located close to midline, longer spine on basal segment of antennal exopodite, and in the presence of extremely large projections on exopodites IV–V. Celsinotum candango differs from Brazilian C. laticaudatum Smirnov & Santos-Silva, 1995 in a shorter spine on basal segment of antenna exopodite, in the shape of postabdomen and in morphology of postabdominal denticles. At present, Aloninae fauna of Brazil includes 35 species, and true diversity is undoubtedly higher, with more new species to be expected in the country.

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

Este trabalho apresenta um inventário preliminar de cladóceros fitófilos do Parque Nacional das Emas. Onze amostras qualitativas foram coletados de diferentes ambientes (lagoa, vereda e campo úmido), no período de 2000 a 2006. Foram identificadas 18 espécies, pertencentes a famílias tipicamente não planctônicas, sendo Chydoridae a mais especiosa. Todas elas representam o primeiro registro para a região sudoeste de Goiás.

A cladistic analysis of the genera of the Macrothricidae (Crustacea, Cladocera, Radopoda) was performed based on 36 morphological characters, and including 15 terminal taxa (three as outgroups). The single tree obtained from this analysis supported the monophyly of Macrothricidae and Macrothricinae. The group called as "non-Macrothricinae" was indicated as paraphyletic. Neothricidae was also not supported.
