Apostolepis is a diverse genus of dipsadid snakes, currently comprising 34 species occurring in most cis-Andean South America. The taxonomy of the group is highly unstable. Upon discovering its type series, we redescribe the rare species A. ambiniger (Peters, 1869) and provide an account of its geographic distribution and morphological variation in pholidosis, osteology, and hemipenial characters. We also discuss some aspects of the taxonomy of Apostolepis.

The genus Dipsas includes approximately 32 species, distributed from Mexico to South America (Brazil, Argentina, Paraguay, Bolivia and Peru). High variability in color pattern and scalation has made it difficult to define limits among Dipsas species and to interpret patterns of geographic variation. We analyzed 14 meristic and 18 morphometric characters of 483 specimens of D. catesbyi and 129 specimens of D. pavonina, as well as their color pattern, coloration, hemipenis, cephalic glands and geographic distribution. We describe variation in meristic and morphometric characters and incorporate new characters into revised diagnoses. The results indicate a greater morphological similarity between D. catesbyi and species of Sibynomorphus than with the other species of Dipsas. More morphological studies should be done to evaluate current phylogenetic proposals for relationships within the tribe Dipsadini.

Colletes neoqueenensis Friese, 1910 is a rare species from southern Argentina known to me from its type series only. The species has also been recorded from Chile, but its occurrence in that country remains to be confirmed. Examination of some museum specimens misidentified as C. neoqueenensis indicates that bee taxonomists are often unaware of its actual identity. To clarify this, I provide a series of diagnostic characters as well as a detailed redescription of the female lectotype. High quality photographs of the type specimen are also given so the species can be more easily identified.

Amphisbaenaslateriis a rare species of worm lizard from Peru and Bolivia, known only from three specimens. We found two additional specimens of this taxon, housed at the herpetological collections of the Zoological Museum (Cenak), Universität Hamburg, and the University of Kansas Biodiversity Institute, updating its known geographic distribution and morphological variation. We also discovered an unpublished manuscript by late Carl Gans reporting the finding of the Hamburg specimen, which we reproduce here with the permission of his family.Amphisbaenaslaterican be identified by a combination of characters including counts of annuli, segments, and pores, the shape of head scales and color pattern. Basic morphological data is given for all species of Amphisbaenia known for Bolivia and Peru to aid in the identification of specimens from those countries.

Lophostoma carrikeri is a bat species widely distributed in the northern portion of South America and has been reported in a great variety of forested habitats. However, it is still poorly represented in scientific collections and wildlife surveys. In Brazil, L. carrikeri is known mainly for the Amazon basin and few localities in the Cerrado and Caatinga biomes. Here we report the first records of Lophostoma carrikeri from the states of Minas Gerais and Ceará based on specimens examined in taxonomic collections and collected during fieldwork. These new records represent the easternmost limits on the distribution of L. carrikeri and expand its known geographic range in approximately 488 km southeast and 490 km east of the nearest known records (São Domingos, state of Goiás and Teresina, state of Piauí). We also provide measurements, comments on morphological variation and an overall review of the species geographic distribution.

Distributional and biological data for some bat species in South America are scarce, mainly in non-phyllostomid bats. Herein we provide new records of two rare species of aerial insectivore bats for southeastern Brazil, Histiotus montanus and Molossops neglectus. In addition, we report facial morphological variation in color and new records of ectoparasites for H. montanus. For M. neglectus we performed a Principal Component Analysis (PCA) to check for morphometric variation based on forearm and skull dimensions, the southerly distributed specimens showing slightly smaller measurements than the northern ones.

Vanilla labellopapillata is reported for the first time from the state of Mato Grosso, in the Southern Brazilian Amazon. This rare species is currently known only from a handful of specimens collected in the Central and Oriental Amazon. Based on the new collection, both the geographical range and morphological variation of V. labellopapillata increase significantly. We present an updated description, taxonomic and ecological comments, geographic distribution data, illustrations in line drawing and photographs.

The Cinereous Warbling-finch Poospiza cinerea is a globally vulnerable Emberizidae passerine, patchily distributed and rare in the open savannah of central South America. Attributes of rare species include niche specificity such as feeding habits. To verify possible niche specialization in this species we aimed to describe its foraging habits related to substrate use, foraging and substrate height, attack maneuvers, and consumed food items. We monitored two groups at two study sites and sampled foraging events with intervals of 15 minutes. The substrates used in greater frequency were foliage and reproductive organs. Foraging and substrate height varied widely with study area. The attack maneuver adopted in greater frequency was glean. Most food items attacked were small invertebrates. Big invertebrates included Lepidoptera, Hemiptera, Coleoptera, Hymenoptera and Orthoptera. Poospiza cinerea was also recorded foraging in mixed bird flocks with seven other species. The generalist foraging behavior of the species cannot be associate to its rarity.

New northwestern records of the striped treefrog Hypsiboas caingua (Carrizo, 1991 “1990”) are presented for Brazil, extending its known geographic distribution approximately 115 km northward (linear distance) of the previous northernmost record of the species. In all new localities, individuals of H. caingua were only found in calling activity under temperatures below 18°C. The species appears to be associated with Atlantic Forest, although it had already been recorded in Cerrado. Although the scientific literature data suggests that H. caingua presents discontinuous geographical distribution, three methods of distribution modelling based on climatic data show that the species' distribution is continuous. The gap in the distribution may be related to the lack of field surveys in the regions that connect these populations, especially in colder periods. Nevertheless, factors other than climate might also be responsible for the current distribution of H. caingua, since the species was absent in well-surveyed sites situated between the areas of modeled distribution. Therefore, further studies on natural history, populations' genetic structure, and geographic distribution models implementing factors other than climate will be important to elucidate some ecological and evolutionary aspects of the distribution of H. caingua in South America.

Ganoderma is a cosmopolitan genus of fungi with species distributed in temperate and tropical regions. Species of Ganoderma in living Leguminosae were observed in Park de la Salud in Pance, Cali, Colombia and we record G. multiplicatum for the first time from Colombia. A distribution map of this genus in the Neotropical region is presented.
