Remains of a new titanosaur, Aeolosaurus maximus sp. nov., from the Adamantina Formation (Upper Cretaceous), Bauru Group, São Paulo State of Brazil are described. The new species is represented by a single partially articulated skeleton and is characterized by having a well-developed posterior protuberance below the articular area on the anterior and middle haemal arches and a lateral bulge on the distal portion of the articular process of the mid-posterior haemal arches. It shares with other Aeolosaurus species the presence of prezygapophyses curved downward on anterior caudal vertebrae and haemal arches with double articular facets set in a concave posterodorsal surface. These two characteristics are interpreted here as synapomorphies for the genus Aeolosaurus. The new diagnosis for the genus Aeolosaurus does not support the inclusion of Gondwanatitan within Aeolosaurus as previously proposed by some authors. The phylogenetic analysis recovered the two Aeolosaurus from Argentina as sister groups with A. maximus and Gondwanatitan as progressively more basal taxa (Gondwanatitan (A. maximus (A. rionegrinus, A. colhuehuapensis))). Additionally, according to the results of the phylogenetic analysis performed in this work, the taxa Panamericansaurus, Rinconsaurus, and Maxakalisaurus are also nested within Aeolosaurini, being more basal than Aeolosaurus and Gondwanatitan. On the basis of the stratigraph-ical range of the Aeolosaurus occurrences in Argentina and the age proposals based on microfossils for the Bauru Group, it is assumed a Campanian–Maastrichtian age for the top of the Adamantina Formation for the Monte Alto region in São Paulo State and the bottom of the Marília Formation in Peirópolis, Minas Gerais State—the places where Aeolosaurus remains have been reported in Brazil.

The record of non-mosasaur squamates (Reptilia, Squamata) is sparse in the Cretaceus fossil record of Brazil and include six putative reports, three from the Aptian-Albian of the Araripe Basin (Tijubina pontei Bonfim-Júnior and Marques, Olindalacerta brasiliensis Evans and Yabumoto, and a lizard indet.) and three from the Upper Cretaceous of the Bauru Group (Pristiguana brasiliensis Estes and Price, Anilioidae gen. et sp. indet., and Squamata gen. et sp. indet.). In this contribution, a new genus and species of lizard, Brasiliguana prudentis gen. et sp. nov., is described based on an isolated left maxilla with teeth. The material was discovered in an outcrop of the Upper Cretaceous Adamantina Formation (Bauru Group) located in the proximity of Presidente Prudente Municipality, São Paulo State, Brazil. The new taxon is considered a basal non-Priscagamidae+Acrodonta iguanian based on the presence of a weakly inclined anterior margin of the maxillary nasal process and maxillary tooth shape and tooth implantation similar to that of iguanians rather than of other lizard groups (e.g. teiids). This finding significantly increases the squamate lizard diversity of South America, which is still poorly understood and sparsely represented in the fossil record.

Lithic blades are long and narrow flakes produced from prepared cores which form part of different technological complexes all around the world. In South America, the production and use of blades has been reported in different settings which include early hunter-gatherer occupations of the Pleistocene-Holocene transition, as well as Middle and Late Holocene occupations. Until now, the only reference to blade technology in Brazil comes from the south and corresponds to Early Holocene hunter-gatherer assemblages. This paper presents a second record of lithic blades in Brazil, which includes one fragment and three refitted artifacts manufactured from fine-grained silicified sandstone recovered from a surface site (Picão), which is located in the Dourado Municipality, central São Paulo state. Analysis undertaken on the blades involved the collection of metric data, including longitudinal curvature, and the elaboration of diacritic schemes which consider the direction and order of the observed remnant scars for interpreting the chronological sequence of removals. Results indicate the production of ³70.5 mm-long, softly curved blades, with evidence of preparation of the point of impact prior to extraction from the core, as well as the presence of unidirectional, parallel scars related to blade production from a single striking platform. These reduction characteristics resemble those encountered in the nearest contexts of southern Brazil and northern Uruguay, although differences also exist. In spite of the lack of chronological data, this new record of blades in central São Paulo state calls for more research into the origins and dispersion of this technology in southeastern South America.

Heimbra bicolor Subba Rao, 1978 (Hymenoptera, Eurytomidae) was previously known in Mexico, Argentina, Paraguay, and Brazil, with records in Federal District and Rio Grande do Norte, Minas Gerais, and Santa Catarina states. Here, we newly report this species from the state of São Paulo based on three females collected at Estação Ecológica de Jataí, in the municipality of Luiz Antônio, São Paulo state, Brazil. Additionally, we provide a map with the geographical distribution of the species based on the new record and literature. This record increases the number of species of Heimbra known in São Paulo state to two species.

ABSTRACT (Freshwater hyphomycetes in a preserved insular system from Brazil: first records at Parque Estadual da Ilha do Cardoso, municipality of Cananéia, São Paulo State). To survey freshwater hyphomycetes from insular water bodies at the Parque Estadual da Ilha do Cardoso State Park, in Cananéia municipality, São Paulo State, Brazil, submerged mixed leaf litter samples were collected from six sites from June 2012 to February 2013. The samples were taken to the laboratory and incubated in Petri dishes containing sterile distilled water at room temperature (20oC). From the 5th day on, until at least one month, fragments of the leaf litter samples were examined under the microscope, resulting in the morphological identification of 33 taxa. Among those, two are new records for the state of São Paulo and four for Brazil. Descriptions and pictures of each new record are presented.
