This research describes the infestation by ticks and lice in free-living coatis (Nasua nasua Linnaeus, 1766) with sylvatic and synanthropic habits living at the Iguaçu National Park (INP), state of Parana, southern Brazil. During the months of September 2014 and from March to April 2015, ticks and lice were collected from 86 free-living coatis from INP. Among the animals analyzed, 99% (85/86) were infested with ectoparasites, Amblyomma spp. larvae (n=23), nymphs of Amblyomma brasiliense (n=77), Amblyomma coelebs (n=427) and Haemaphysalis juxtakochi (n=6) being observed, as well as Amblyomma ovale adults (n=46). Lice were found in lower prevalence (13%, 11/86), nymphs (n=31) and adults (n=9) of Neotrichodectes pallidus. Summary results show feral coatis with sylvatic and synanthropic habits as competent hosts for ixodid ticks and lice, arthropods responsible for the transmission of pathogens for carnivores, others wildlife and humans. This paper presents the first record of H. juxtakochi infesting coatis in Brazil.

One new species of the genus Oleia Andersen et Mendes, 2007 (Diptera: Chironomidae: Orthocladiinae), O. fieldsi sp. n. is described and figured as adult male. The specimens were collected in a fragment of secondary forest in the Atlantic Forest, at Iguaçu National Park, on the border of Argentina and Brazil.

The number of described anurans has increased continuously, with many newly described species determined to be at risk. Most of these new species inhabit hotspots and are under threat of habitat loss, such as Brachycephalus, a genus of small toadlets that inhabits the litter of the Brazilian Atlantic Rainforest. Of 36 known species, 22 were described in the last decade, but only 11 have been assessed according to the IUCN Red List categories, with just one currently listed as Critically Endangered. All available data on occurrence, distribution, density, and threats to Brachycephalus were reviewed. The species extent of occurrence was estimated using the Minimum Convex Polygon method for species with three or more records and by delimiting continuous areas within the altitudinal range of species with up to two records. These data were integrated to assess the conservation status according to the IUCN criteria. Six species have been evaluated as Critically Endangered, five as Endangered, 10 as Vulnerable, five as Least Concern, and 10 as Data Deficient. Deforestation was the most common threat to imperiled Brachycephalus species. The official recognition of these categories might be more readily adopted if the microendemic nature of their geographical distribution is taken into account.

The worker, queen and male of the ant Typhlomyrmex meire Lacau, Villemant & Delabie new spe- cies (Ectatomminae: Typhlomyrmecini) are described from the Brazilian Atlantic rainforest. This endemic species from southern Bahia is easily distinguished from all other members of the genus by the peculiar morphology of mandibles and the reduction of the antennal segments observed in both sexes. We provide a partial redefinition of the genus diagnosis taking into account the antennal structure of the new species. A new identification key for workers is provided.

AbstractA long terrestrial record, Colônia CO-3, from the Atlantic rainforest region in Brazil (23°52′S, 46°42′20 ʺW, 900 m a.s.l.) registrates variations in the forest expansion during the last 100,000 yr. The 780-cm depth core was analyzed at 2-cm intervals and arboreal pollen frequencies were compared to nearby speleothem stable isotope records and neighboring marine records from the tropical Atlantic. To evaluate regional versus global climate forcing, our record was compared with Greenland and Antarctic ice-core records. These comparisons suggest that changes in temperature seen in polar latitudes relate to moisture changes: e.g., to changes in the length of the dry season, in tropical and subtropical latitudes during glacial as well as interglacial times. These climatic changes result from changes in the frequency of polar air incursions to these latitudes inducing a permanent cloud cover and precipitation. This is an important result that should help define paleoclimatic features in the Southern Hemisphere for the last glaciation.

Three new Brazilian species of Aulonemia, a Neotropical woody bamboo genus, are described and illustrated: Aulonemia cincta, with its distinctive corky girdles; Aulonemia prolifera, characterized, among other Brazilian congeners, by its fimbriate leaf sheaths; and Aulonemia soderstromii, with its conspicuous cluster of spreading fimbriae. These new species all propagate by amphipodial rhizomes, an unusual feature shared with the Brazilian species A. aristulata, with which they are morphologically compared. Comments about habitat, distribution, phenology, and conservation status for each species are provided, as well as photographs taken in the wild.
