| Ruellia simplex, the name of a species of Ruellia described from Cuba in 1870, is the oldest name for the neotropical species generally known as Ruellia tweediana, Ruellia coerulea and Ruellia malacosperma. Therefore Ruellia simplex has priority and reduces tha latter names to synonym. This species has an amphitropical distribution in the New World, being found in southern United States, Mexico and the Antilles, and in western Bolivia, southwestern Brazil, Paraguay, Uruguay, and northeastern Argentina. |

| ABSTRACT. Coptochilus Amyot & Serville, 1843 is distinguishable from the other Neotropical Scutelleridae by the dorsally concave head, with lateral margins of mandibular plates elevated. Here we describe and revise the species of Coptochilus based on general and genital morphological traits. Coptochilus castaneus (Dallas, 1851), once synonymous with C. ferrugineus Amyot & Serville, 1843, is revalidated, and a new species, C. morrisi, is described from French Guiana. A key to the five species in the genus is provided. |

| The lesser grison (Galictis cuja) is one of the least-known mustelids in the Neotropics, despite its broad range across South America. This study aimed to explore current knowledge of the distribution of the species to identify gaps in knowledge and anticipate its full geographic distribution. Eighty-nine articles have mentioned G. cuja since 1969, but only 13 focused on the species. We generated a detailed model of the species' potential distribution that validated previous maps, but with improved detail, supporting previous southernmost records, and providing a means of identifying priority sites for conservation and management of the species. |

| ABSTRACT. A large collection of terrestrial isopods from different Brazilian regions was examined. Two new species of Amazoniscus Lemos de Castro, 1967 (Scleropactidae) are described: A. zimmeri Campos-Filho, Montesanto & Araujo sp. nov. from the state of Pará and A. schmidti Campos-Filho, Montesanto & Taiti sp. nov. from the state of Minas Gerais. Pseudotyphloscia alba (Dollfus, 1898) (Philosciidae) is firstly recorded from Brazil. The systematic position of Venezillo tuberosus (Budde-Lund, 1904) is discussed and transferred to Ctenorillo Verhoeff, 1942. Androdeloscia lejeunei (Lemos de Castro & Souza, 1986) and Diploexochus echinatus Brandt, 1833 from the state of Pará, are redescribed. |

| Munduruku gen. nov. is proposed for the type species Munduruku bicoloratum sp. nov., from Juruti and Santarém, Pará, Brazil. The main diagnostic character of Munduruku gen. nov. is the presence of a subapical, lanceolate keel on the male palpal bulb, which is unique among the basal taxa of Theraphosinae with type III-IV urticating setae. The female spermathecae consist of two spheroid receptacles with funnel-shaped necks, each of which bears a sclerotized area. In both sexes, the abdomen is remarkably patterned, an uncommon feature in adults of New World theraphosids. Both the bulbus lanceolate keel and the abdominal color pattern are hypothesized as synapomorphies of the genus. |

| We studied the natural diet of two didelphid marsupial species, Didelphis aurita and Philander frenatus, at a rural area on southeastern Brazil, through fecal sample analysis. Data analysis included intraspecific comparisons (age, gender, and climatic seasons) and interespecific comparisons. Frequencies of food items were compared with other studies to analyze diet differences in a spatial scale. Invertebrates were the most frequent food category found in samples of both species, followed by fruits and vertebrates. There were no differences in the consumption of invertebrates, vertebrates and fruits between sexes in the two species, but both consumed more fruits in more humid months. Juveniles of P. frenatus consumed less vertebrates than adults or... |

| As a result of a systematic review of nectar feeding bats in the genus Lonchophylla (Phyllostomidae) deposited in the scientific collections of the Instituto de Ciencias Naturales (ICN) in Bogotá and the Museo de Historia Natural of the Universidad del Cauca (MHNUC) in Popayán, we report range extensions for three Colombian species. Lonchophylla cadenai is reported from Pueblo Rico, Risaralda, representing an increase in both altitudinal and latitudinal ranges; L. handleyi is reported from Cueva de los Guácharos, Huila, confirming the presence of this taxon in Colombia and representing its northernmost known record; and L. pattoni is reported from Leticia, Amazonas, which constitutes the third known collecting locality for this taxon and represents the... |

| The distribution and range of the 45 South American species of Carnivora (except Pinnipedia) currently recognized taxonomically was delimited from a detailed study of the literature. This study analyzes the ecogeographic patterns that operate at a continental scale in this family, which are particularly peculiar for not respecting natural landscape frontiers. The relation between the species distribution and latitudinal bands was evaluated using a Geographical Information System (GIS) with statistical regressions and correlations being carried out between geographical variables, areas, species richness, and latitude. The latitudinal bands with a higher species richness corresponded to the tropical bands with larger quantity of ecoregions, whereas a marked... |

| A taxonomic revision of the genus Guatteria, including the former genera Guatteriella, Guatteriopsis and Heteropetalum is given. Within the genus Guatteria 177 species are recognized, 25 of which are new. Included are chapters on the history of the taxonomy of the genus, morphology, wood anatomy, karyology, palynology, chemistry, flower biology and pollination, dispersal, distribution and ecology, phylogeny and molecular studies, conservation, and uses. A synoptical key to all species is included, as well as two dichotomous keys, one for the species of Central America and Mexico, and one for the species of NE, E and SE Brazil. The species treatments include descriptions, full synonymy, geographical and ecological notes, vernacular names and taxonomic... |

| During field work in Venezuela and Brazil a difference in call was noticed between specimens of large hylids of the Hyla boans-group. Based on this and on morphological differences, it was concluded that Hyla wavrini Parker, 1936, up till now considered a synonym of Hyla boans (Linnaeus, 1758), should be considered a valid species, of which Hyla miranda-ribeiri Melin, 1941 is a synonym. Durante trabajo de campo en Venezuela y el Brasil se nota una diferencia en el canto de especimenes de gran Hílidos del grupo Hyla boans. Basandose en este observación y en diferencias morfológicas, se concluye que Hyla wavrini, considerado até horita como sinónimo de Hyla boans debe ser considerado como especie valido, y que Hyla miranda-ribeiri es un sinónimo de el.... |

| Salpichlaena is a distinctive fern genus characterised by 2-pinnate climbing fronds with indeterminate growth. The number of species in the genus has been a matter of debate. Taxonomic studies are made difficult by within-frond variability in pinna morphology and size, and by herbarium material being incomplete. We systematically documented 62 morphological traits in 283 herbarium specimens and sequenced 52 Salpichlaena and 11 outgroup specimens. DNA sequences included plastid genes (rbcL, rpoC1 and rps4), intergenic spacers (rps4-trnS, trnHpsbA and trnG-trnR) and a nuclear gene (pgiC). Phylogenetic analyses based on the plastid markers divided the samples into six major clades. We recognise the three deepest clades as distinct species (S. hookeriana, S.... |
