| Jururumberus n. gen. is erected based on the males of J. arapuca n. sp. from São Paulo State, in southeastern Brazil and J. uatuma n. sp. from the Amazonas in northern Brazil. The genus can be separated from other Orthocladiinae based on the combination of bare eyes, wing, and squama; frons U-shaped, extended ventrally; AR ≤ 0.3, antenna without apical seta; palp short, five-segmented, with sensilla clavata in subapical sensillum coeloconicum; no acrostichals; costa strongly extended; R4+5 ending proximal to M3+4; anal point narrowly triangular with microtrichia only, sitting high on tergite IX; and virga composed of two spines. |

| An inventory of macroinvertebrates conducted in the Contas River basin in Northeastern Brazil found 13 species of freshwater mollusks. Most of the community was represented by pulmonate gastropods, including Physa acuta, Drepanotrema anatinum, D. cimex, D. lucidum, Biomphalaria straminea?, Gundlachia radiata?, G. ticaga and Hebetancylus moricandi; the prosobranchs Pomacea archimedis?, Melanoides tuberculata and Littoridina sp. were also found. Bivalves were less diversified, represented only by Pisidium pulchellum? and Eupera simoni?. The taxonomic composition and the small size of many species reflect the intermittent condition of the basin. Additionally, the occurrence of shells of five terrestrial species (Helicina angulata, Gastrocopta pellucida... |

| Studies that organize lists of species are essential and act as the starting point for future discussions on the ecology of fish in environments that are poorly studied. The present paper describes the fish assemblage of the hydrographic basin of Chasqueiro Stream, an important component of the Mirim Lagoon system. Fish were collected during one year period between August/2012 and July/2013 in six sites, comprising three biotopes: upstream, reservoir and downstream. A total of 22,853 specimens were collected, and were distributed into 83 species, 20 families, and eight orders. The two species with the largest number of individuals captured were Bryconamericus iheringii with 2,904 (12.71%) and Cheirodon ibicuiensis with 2,868 (12.55%). Characiformes and... |
