Studies on fish parasites in Pampulha dam, Belo Horizonte, Minas Gerais, Brazil, found specimens of Poecilia reticulata Peters, 1859 harboring natural infection by larval stages of tapeworms. A total of 250 specimens of P. reticulata were collected and analyzed between February and August 2010, of which 23 were found infected (prevalence 9.2%) with one metacestode each (mean intensity 1, mean abundance 0.09). The analyses of the parasites, particularly the morphology of rostellar hooks, made it possible to identify Glossocercus auritus (Rudolphi, 1818). This is the first report of G. auritus metacestode in South America and P. reticulata is a newly known host for this parasite.

Pleurolophocercous cercariae emerged from naturally infected Melanoides tuberculata from Minas Gerais State, Brazil, were used to perform experimental infection of laboratory-reared Poecilia reticulata. Mature metacercariae were obtained from the gills of fishes and force-fed to Mus musculus. The adult parasites which recovered from small intestines of mice were identified as Centrocestus formosanus. This is the first report of M. tuberculata as intermediate host of this heterophyid in Brazil.

Radiometric dating of basement rocks in South America by the M.I.T. geochronology laboratory has indicated the following thermo-tectonic episodes. The gneisses of the Imataca Complex of the Venezuela Guayana Shield are about 3000 m.y.; they have been intruded by igneous rocks of 2000 m.y. age. Ancient rocks between these age values have been found in the Bação Complex in Minas Gerais. The principal cratonic rocks of southeastern Venezuela, the Guianas, northern Brazil in the Amapa district, the coast region between Belém and São Luis, the region west of the Tocantins River, and in the São Francisco area near Salvador all show ages in the range 2000 ± m.y. The region in northeast Brazil represented by the Cariri orogenic belt shows an average Rb–Sr whole-rock isochron age value of 640 m.y. K–Ar age values in the Belo Horizonte district, Minas Gerais, show a metamoprhic overprint value of 500 m.y. A similar value is found in Colombia, east of the Macarena mountains.

During studies on the participation of larval Odonata in the life cycle of trematodes carried out at the Pampulha reservoir, Belo Horizonte, State of Minas Gerais, Brazil, between May and September 2011, dragonfly larvae, Orthemis discolor (Burmeister, 1839) and Perithemis mooma Kirby, 1889, were found harboring metacercariae identified as Eumegacetes medioximusBraun, 1901. This is the first report and morphological description of metacercariae of E. medioximus in the Neotropical region.

Melanoides tuberculata that naturally harbored trematode larvae were collected at the Pampulha dam, Belo Horizonte (Minas Gerais, Brazil), during malacological surveys conducted from 2006 to 2010. From 7,164 specimens of M. tuberculata collected, 25 (0.35%) were infected by cercariae, which have been morphologically characterized as belonging to the Megalurous group, genus Philophthalmus. Excysted metacercariae were used for successful experimental infection of Gallus gallus domesticus, and adult parasites recovered from the nictitating membranes of chickens were identified as Philophthalmus gralli. This is the first report of P. gralli in M. tuberculata in Brazil.

During a study on filamentous fungi in the soil of mountainous environments in the state of Minas Gerais, Brazil, one specimen of Mortierella verticillata Linnem. was isolated. Fungal identity was confirmed by morphology and ITS rDNA sequence analysis. This study reports the first occurrence of M. verticillata in South America. This species is distinguished by its monopodial sporangiophores growing on aerial hyphae of verticillate branches, and single-spored sporangia finely ornamented with a diffluent wall. In this manuscript, the specimen is described and illustrated, and the distribution of this species is discussed.

During a helminthological survey on bats from Minas Gerais state, Brazil, we found 3.13% of bats parasitized with capillarids. Aonchotheca pulchra (Freitas, 1934), Tenoranema rivarolai (Lent et al., 1946), and some specimens of capillarids non-identified were registered. This is the first report of A. pulchra in Minas Gerais state and the second report of T. rivarolai in South America.

As a supplement to the recent review of H. V. Walter's book, The Prehistory of the Lagôa Santa Region, some additional information about the nature of his recent archaeological work is of interest. After the completion of our own year of archaeological field work in the Lower Amazon, three days were spent in the Lagôa Santa Region, Belo Horizonte, Minas Gerais with Mr. H. V. Walter studying his collections, and visiting and excavating with him some of the rock shelters and caves. Two sites, not mentioned in his report, are of such archaeological importance in the preceramic cultural history of South America that they should be brought to the attention of other archaeologists.By way of introduction, it should be stated that Mr. Walter, the British Vice-Consul in Belo Horizonte, is primarily interested in paleontological data, a quest which for fifteen years has led him to extensive exploration at his own cost in the caves in and around the Lagôa Santa region.
