Brazil is one of the world's largest countries with a rich diversity of wildlife, including resident and migratory wild birds, which may be natural reservoirs of the Newcastle disease virus (NDV). Because Brazil is a major global exporter of chicken meat, the emergence of such a disease may have a huge negative impact not only on the economy due to trade restrictions and embargoes, but also on the quality of life of the population. Samples were collected from 1,022 asymptomatic domestic and wild birds from the Brazilian coast and the Amazon region using tracheal/cloacal swabs and tested by RT-qPCR. The results showed 7 (0.7%) birds were positive for NDV. The positive samples were then isolated in embryonated chicken eggs and their matrix protein genes were... |

ABSTRACT The genus RhophitulusDucke, 1907 is a large and complex group of bees of the tribe Protandrenini comprising small, slender, mostly black ground-nesting species that are restricted to South America. We describe a new species of Rhophitulus from Parque Nacional São Joaquim, Urubici, state of Santa Catarina, Brazil. Rophitulus ater sp. nov. is distinctive and easily distinguished from other species of the genus by a unique combination of morphological characters in both sexes, but especially by the following: dull black body, coarsely and densely punctate integument, basal area of metapostnotum depressed and areolate rugose, posterior margin of hind tibia and pygidial fimbria of female with blackish pilosity, and characters of the male genitalia with... |

Panurgine bees are diverse and abundant in temperate areas of the Americas but poorly represented to nearly absent in the tropics. We describe and illustrate five distinctive new species of the genus Protandrena that occur at high altitudes (2000-3400 m) in the Andes, from Venezuela to Ecuador. The species are also described to make the names available in forthcoming papers on their biology. These Andean species resemble some members of the subgenus Heterosarus but differ from it, as well as from any other subgenera of Protandrena, primarily in characters of the male genitalia and hidden sterna. The South American Protandrena s. l. are morphologically highly diverse and a complete study of the group is needed before supraspecific names are proposed for... |

The impact of the discovery of Temnocephala haswelli Ponce de Léon, 1989, described as ectosymbionts of ampullariid apple snails outside of Uruguay, motivated us to collect a large number of specimens of Pomacea canaliculata (Lamarck, 1822) from several localities in the southern portion of the state of Rio Grande do Sul. This species was recorded three times after its description: in a study of chromosomes, in a study about the ultrastructure of the collar receptor cells, and in a study of the Haswell glands, all conducted in Uruguay. A total of 301 specimens of P. canaliculata were collected from 1999 to 2007. Temnocephalans found in the pallial cavity were identified as T. haswelli, which occurred in single infestations or concurrently with Temnocephala... |

ABSTRACT We describe a new genus and a new species in the family Epiphragmophoridae, Minaselates paradoxa sp. n. The new species was found at the National Park Cavernas do Peruaçu, in northern portion of the state of Minas Gerais, Brazil. Minaselates paradoxa sp. n. is classified in Epiphragmophoridae based on the fact that it shares the following diagnostic features of the family: a dart apparatus with a single dart sac, and two unequal mucous glands at the terminal genitalia. Minaselates gen. n. differs from Epiphragmophora Doering, 1874 by having a granulose protoconch, shell spire with blunt apex, complex microsculpture on the teleoconch and closed umbilicus fused with the shell wall. Also, significant differences between the two genera are the... |

Limnoperna fortunei (Dunker, 1857), during its invasion process in South America, has caused severe impacts both on natural environments altering native biodiversity, ecosystem structure and function-, and on man-made structures causing economic looses. Twenty-one samples were taken from the right bank of the Uruguay River, from tributaries of the Uruguay and Paraná Rivers, the drainage of the Esteros del Ibera Wetland. Based on this fieldwork, the presence of larvae and adults of L. fortunei was determined. Also, through the comparison of environmental characteristic with the known tolerance limits for the species, the possibility of its establishment in environments not yet invaded was determined. Most of the sampling stations have features that allow... |

ABSTRACT Nungara gen. nov. is proposed to include the type species, Nungara niveomaculata (Mello-Leitão, 1941) comb. nov., transferred from Olios Walckenaer, 1837 and two new species, described from males and females: N. anama sp. nov., from the states of Sergipe, Alagoas and Espírito Santo, and N. gaturama sp. nov., from the states of Sergipe, Bahia and Espírito Santo, all in Brazil. The new genus is distinguished from all other Neotropical sparassid genera by the presence of a deep tegular groove on the male palpal bulb and a hood-like projection on the median septum of the female epigyne. In addition, Olios fuscovariatus Mello-Leitão, 1943, Stasina koluene Mello-Leitão, 1941 and Polybetes proximus Mello-Leitão, 1943 are transferred to Nungara gen. nov.... |

The life-history and biology of Dirphia araucariae Jones, 1908, including its life fertility table, are here described. Moths were reared in the laboratory under controlled conditions on their host plant, Araucaria angustifolia (Bertoloni) O. Kuntze - Araucariaceae. We describe several life-history traits of the species, namely: developmental period, survival rate, growth rate, fertility, fecundity, sex ratio, cephalic capsule width, and pupal weight. Mean duration of life stages were: egg = 26.78 days; larva = 61.78 days; prepupa = 6.85 days; pupa = 62.46 days; adult = 8.37 days. We found statistically significant differences between sexes for adult, larval and pupal stage duration; larval stage was longer in females while pupal stage was longer in males.... |

Temnocephala rochensis Ponce de Léon, 1979, was the second of four species of Temnocephala Blanchard, 1849 to be described as ectosymbiont of ampullariid apple snails, Pomacea canaliculata (Lamarck, 1822). There have been no records of this Uruguayan species after its initial description. As part of the present study, 111 specimens of P. canaliculata were collected between 2003 and 2009. Temnocephalans found in the pallial cavity were identified as T. rochensis, occurring in single infestations, or concurrently with Temnocephala haswelli Ponce de Léon, 1989. Specimens of T. rochensis showed a conspicuous red eye pigment which faded after ethanol fixation. Important taxonomic characters of the reproductive system were evidenced by several techniques, and... |
