| Termite mounds are known to offer refuge and microhabitats to a great variety of invertebrates and vertebrates. In the valley of the upper Tocantins River, within areas of influence of hydroelectric power plants 4,000 termite mounds were surveyed to evaluate the diversity of amphibians and reptiles using these environments. Surveys in termite mounds from two other areas (Corumbá River and Araguaia River basins) were used for comparative purposes. The results for termitaria in the upper Tocantins river valley revealed nine families, 13 genera, and 25 species of amphibians, and 16 families, 32 genera, and 47 species of squamate reptiles. Compared to a general herpetofaunal list of the region, the data indicate that between 30.6% and 56.8% of the species use... |

| Anomaloglossus praderioi was originally described as Colostethus praderioi by E. La Marca in 1998 on the basis of two male specimens. The present paper provides a redescription of the species on the basis of new material from Maringma Tepui in Guyana and an additional specimen from Sierra de Lema in Venezuela. The redescription includes descriptions of the tadpole and vocalisation. Anomaloglossus praderioi is a medium-sized species mainly distinguished from its known congeners in having Fingers I, II and IV equal in length, the tip of Finger IV barely reaching the base of the distal subarticular tubercle on Finger III when fingers are adpressed, Fingers II and III with preaxial keel-like lateral folds, toes basally webbed with folded flaplike fringing... |

| Abstract A revision of the genus Macromalthinus resulted on recognition of twelve species, six of which are herein proposed as new: Macromalthinus belemensis Brancucci, 1981, M. brasiliensis (Pic, 1906), M. globuliventris Brancucci, 1981, M. guyanensis sp. nov., M. luteoapicalis sp. nov., M. maximicepsPic, 1919, M. orapuensis sp. nov., M. piceiventris sp. nov., M. quadratithorax sp. nov., M. santaremensis Brancucci, 1981, M. schmidli Constantin, 2010 and M. xerophilus sp. nov. No taxonomic changes were necessary in the previously described species, which are distinguished through differential diagnosis and an updated identification key. The type specimens of all species were revisited and their photographs are provided. Discussions on the diagnostic... |

| In the first paper of this series (Albuquerque & Brandão, 2004) we revised the Vezenyii species group of the exclusively Neotropical solenopsidine (Myrmicinae) ant genus Oxyepoecus. In this closing paper we update distribution information on the Vezenyii group species and revise the other Oxyepoecus species-group (Rastratus). We describe two species (Oxyepoecus myops n. sp. and O. rosai n. sp.) and redescribe previously known species of the group [O. daguerrei (Santschi, 1933), O. mandibularis (Emery, 1913), O. plaumanni Kempf, 1974, O. rastratus Mayr, 1887, and O. reticulatus Kempf, 1974], adding locality records and comments on the meagre biological data of these species. We also present an identification key to Oxyepoecus species based on workers. |

| ABSTRACT Daspletosaurus is a Campanian genus of Tyrannosauridae from North America. This genus occupied the same geographic area of Albertosaurus, but remains of Albertosaurus are more abundant than Daspletosaurus. Here is described a subadult maxilla (AMNH FARB 5477) of Daspletosaurus sp. from Montana (USA) and possibly from the Two Medicine Formation. The description is based on Carr (1999) that described cranial ontogenetic variations in tyrannosaurids. The maxilla belongs to the ontogenetic Stage 3 sensu Carr (1999), in which the maxilla is thick, the lateral surface of the bone well sculptured, and the maxillary fenestra is subcircular and well separated from the anterior edge of antorbital fossa. Possibly there were more than one species of... |

| Diapoma is reviewed and four species are recognized: (1) Diapoma thauma, new species, from streams of the rio Jacuí basin, state of Rio Grande do Sul; (2) D. pyrrhopteryx, new species collected from the rio Canoas and streams flowing into this basin in the states of Rio Grande do Sul and Santa Catarina, Brazil; (3) Diapoma terofali, from streams flowing into rio Uruguay in Uruguay and Rio Grande do Sul, Brazil and streams flowing into rio de la Plata, Argentina; and (4) Diapoma speculiferum, from lowland coastal streams in Rio Grande do Sul, Brazil and Uruguay. Diapoma pyrrhopteryx possess the posteroventral opercular elongation typical of D. speculiferum, type species of the genus, but which is absent in D. thauma and D. terofali. Nonetheless, all the... |

| The Dark-winged Trumpeter, Psophia viridis (Gruiformes, Psophiidae) is a Brazilian endemic species and includes three subspecies: Psophia viridis viridis Spix, 1825; Psophia v. dextralis Conover, 1934, and Psophia v. obscura Pelzeln, 1857, as well as P. v. interjecta Griscom & Greenway, 1937, whose validity has been questioned by several authors. These taxa are allopatric in distribution along the south of the Amazon River, although the precise limits of their distribution still remain unknown. This complex has never been taxonomically reviewed and this work aims to test the validity of its taxa based on the Phylogenetic Species Concept. Morphometrical characters and plumage colour patterns were analyzed, and the distribution of the taxa was also... |

| Four additional species are included in the genus Hemistephanus: H. villosus (Kieffer) comb. n. and H. colombiensis (Ceballos) comb. n., transferred from Megischus and redescribed, and H. costaricensis sp. n. and H. stenogulatus sp. n., described as new; H. artiosulcatus Aguiar is proposed as a junior synonym of H. villosus Kieffer. The males of H. arctatus, H. colombiensis, H. submaculatus, and H. villosus are described for the first time. Much new or additional morphometric data is incorporated and discussed for these species and for H. carinatus, H. erugatus, H. erythrocephalus, H. limpidipennis, H. orfilanus, H. ruficeps, and H. velutinus. New geographical records are presented for all mentioned species and for H. cylindricus. Errata for publications... |

| Abstract We present the first record for Loxosceles gaucho Gertsch, 1967 in the Amazonian region of Brazil. Four males, fifteen females and forty-nine immatures were collected in different places in Manaus, Amazonas, Brazil. This is the third species of Loxosceles reported in the Amazon region along with L. amazonica Gertsch, 1967, and L. similis Moenkhaus, 1898. This is the first record of an invasive species of a venomous animal in the state of Amazonas, Brazil, which is noteworthy due to its synanthropic habit, which increases the risk to the local population. |
