This paper reports twelve acarine species belonging to eleven genera in five families, associated with Bambusa sp. (Poaceae), in a woody area from São Paulo State, Brazil. Four species of Tetranychidae (Monoceronychus bambusicola, sp.n.. Oligonychus santoantoniensis, sp.n.. Schizotetranychus longirostris, sp.n. and S. paraelymus, sp.n.) are regarded as new. The genus Cheletomimus Oudemans, 1904 (Cheyletidae) is recorded for the first time to South America.

Neoplecostomus paranensis was the only Neoplecostomus species known from the upper Rio Parana basin, and it was diagnosed from its congeners mainly by the absence or reduction of the adipose fin. In this study we describe three new Neoplecostomus species. All of them are promptly differentiated from N. paranensis by having a well-developed adipose fin. Furthermore, the new species are differentiated from congeners by morphometric and meristic traits, in addition to color pattern. Neoplecostomus paranensis is redescribed. We also provide an identification key to all Neoplecostomus species.

Hyphessobrycon rutiliflavidus, new species, is described from the upper rio Paraguai in Cuiaba, State of Mato Grosso, Brazil. The new species differs from all other congeners by the following combination of characters: black humeral spot, slightly diffuse at its tips, and caudal-peduncle blotch present; midlateral body stripe conspicuous in its posteriormost portion, extending to the tips of the middle caudal rays; anal fin with iii, 15 to iv, 19 rays (mode iv, 17); upper jaw length, 42.3 to 49.5% of the head length; maxilla with 2-5 teeth (mode 3); all the fins of males reddish-orange and of females yellowish.

Because algae are primarily aquatic, it seems almost paradoxical that there Should exist a relatively diversified soil flora where aerophytic cyanoprokaryotes are especially abundant. However, there appear to be relatively few studies oil this topic. This paper aims to improve the taxonomic knowledge oil the chroococcalean and oscillatorialean cyanoprokaryote flora in tropical regions. Samples of cyanoprokaryotes were collected in the rainforest region of the São Paulo State, Brazil. Data oil cyanoprokaryote mass type and color, substratum type, air and mass temperature and humidity, pH and absolute and relative irradiance were collected. The study revealed the presence of 24 species belonging to the orders Chroococcales and Oscillatoriales (12 species each). Aphanothece (four species) was the most species-rich genus. Overall, taxonomic resolution at the species level based oil morphological and morphometric data can still be problematic.

Hemigrammus parana is described from the upper rio Parana system, in the area of influence of the Ilha Solteira reservoir in states of Mato Grosso do Sul, Minas Gerais and São Paulo, southeastern Brazil. The new species differs from all congeners by the combination of the following characters: absence of humeral spot; presence of a roughly triangular or rectangular conspicuous black caudal spot, extending from base to tip of middle caudal-fin rays, its greatest depth at base of caudal-fin rays; and anal-fin rays iii-iv, 18-23.

The Estacao Ecologica de Jata comprises one of the largest mesophytic semideciduous forest and savanna remnants in the state of São Paulo. However, anuran surveys on this site have not been registered in the literature. As result of an exploratory survey conducted in water bodies in the mesophytic semideciduous forest and surroundings in December 2006, we recorded 21 anuran species belonging to five families and 10 genera. These findings contribute to the knowledge of the anuran fauna associated to the mesophytic semideciduous forest of São Paulo state, Brazil.
