| Nassarius levis sp. nov. is described from Canopus Bank, off Ceará, Northeast Brazil, based on shell morphology. It differs from other Brazilian species of the genus in having a more elongate shell, with a weakly developed parietal shield and a notably smooth surface. This last trait has not yet been described among the Western Atlantic Nassarius, but it is common to other congeners from the Eastern Atlantic, such as Nassarius elatus (Gould, 1845) and the Indo-Pacific, such as Nassarius excellens (Kuroda & Habe, 1961). |

| Blatticola cristovata n. sp. (Oxyurida, Thelastomatidae) a parasite of the cricket Anurogryllus muticus (De Geer, 1773) (Orthoptera, Gryllidae) from Argentina, is described and illustrated. This is the first species of the genus Blatticola found parasitizing cricket. This new species is characterized in females by having the cuticle annulated through the body length, the mouth opening is subtriangular and surrounded by eight cephalic papillae, the stoma is short with three pairs placed in two rows of cuticular sclerotised plates, amphids in small pore shaped, oesophagus is divided into three parts, anterior cylindrical corpus, isthmus distinct, and basal bulb valved, the nerve ring is situated around the middle of corpus, the intestine is wide broad... |

| 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... |

| 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 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. |

| Nos trópicos a estação reprodutiva de Butorides striata é relatada na estação chuvosa. Nidifica solitário ou em pequenos grupos, e excepcionalmente formam colônias de 300 a 500 casais. O objetivo deste estudo foi relatar os seguintes aspectos da biologia da nidificação de B.striata: sítio de nidificação, tipo de ninho, características de ovos, período de incubação, período de ninhegos, perda de ninhadas, sucesso reprodutivo e época de nidificação, no município de Porto Esperidião, Mato Grosso. A procura por ninhos ocorreu entre julho de 2009 e maio de 2010. O monitoramento dos ninhos ocorreu em intervalos regulares de três dias. Foram encontrados 115 ninhos ativos. O primeiro ninho ativo foi encontrado no dia 04/01/2010 e o último ninho permaneceu em... |

| RESUMEN Se describe una especie nueva de rana del género Chiasmocleis de los bosques montanos del suroriente del Ecuador, en las laderas occidentales de la Cordillera del Cóndor, entre 1.025-1.630 m de altitud. En base a nuevas secuencias de ADN mitocondrial y nuclear presentamos las relaciones filogenéticas de la nueva especie y sus congéneres. La filogenia muestra una relación cercana a C. antenori, C. carvalhoi, C. magnova, y C. tridactyla. La nueva especie forma parte de un clado integrado por especies que previamente habían sido asignadas al género Syncope. Este clado es hermano de otro conformado por el resto de especies de Chiasmocleis. La nueva especie difiere de sus congéneres por su dorso café ladrillo a café obscuro (sepia) cubierto por puntos... |

| Las ranas ecuatorianas del género Hyloscirtus incluyen 16 especies descritas, de las cuales 11 pertenecen al grupo H. larinopygion. Su distribución se limita a los flancos de la Cordillera de los Andes, tanto al oriente como al occidente. Una evaluación de la herpetofauna en el sector meridional de la Cordillera del Cóndor (bosques montanos sobre mesetas de arenisca) en la provincia de Zamora Chinchipe, Ecuador, condujo al descubrimiento de una especie nueva del grupo que describimos aquí como Hyloscirtus condor sp. nov.; se analizan los renacuajos, las llamadas de anuncio y se estima las relaciones filogenéticas de la especie nueva y de las especies relacionadas en base a nuevas secuencias de los genes mitocondriales 12S, tRNA Val y 16S, con un total de... |

| Abstract The Belem Curassow (Crax fasciolata pinima) is one of the most endangered birds in South America, without sightings of birds in the wild for 40 years. This subspecies is nationally and internationally classified as critically endangered and close to extinction, suffering from poaching and deforestation in its range. Here we present new records of free-living individuals made on three indigenous lands in Pará and Maranhão states: in part of Terra Indígena Mãe Maria, Bom Jesus do Tocantins, Pará; in locations within the Reserva Biológica do Gurupi/Terra Indígena Alto Turiaçu, Centro Novo do Maranhão, Maranhão; and around the Terra Indígena Rio Pindaré, Alto Alegre do Pindaré, Maranhão. We also provide recommendations to protect this bird via a... |

| Fossil remains of birds belonging to the family Phorusrhacidae were studied in several museums of South America, North America and Europe, the main objective being to characterize this family and solve the chaotic state of the nomenclature and classification of these birds. Reconstruction of some species has been done, with the purpose of having an idea about the size, body weight, posture and habit based in their skeletons. The European species, Ameghinornis minor and Aenigmavis sapea are refuted as belonging to this family. Also several forms described from the Tertiary of Argentina are refuted, because they are based on inadequate segments of the skeleton for a good identification, as is the case of the genera Cunampaia, Smiliornis, Pseudolarus,... |
