The two-striped forest-pitviper (Bothrops bilineatus) is an arboreal snake that is currently represented by two subspecies (B. b. bilineatus and B. b. smaragdinus) that comprise a species complex, and its distribution is in the Amazon and the Atlantic Forest. The rarity of encounters with this snake is reflected in the low occurrence of cases of snakebites throughout its geographic distribution and the resulting low number of published clinical reports. However, in some areas, B. bilineatus proves to be more frequent and causes envenomations in a greater proportion. Herein, we review the main aspects of the species complex B. bilineatus, including its biology, ecology, taxonomy, morphology, genetic and molecular studies, geographic distribution, conservation status, venom, pathophysiology and clinical aspects, and epidemiology. In addition, the different antivenoms available for the treatment of envenomations caused by B. bilineatus are presented along with suggestions for future studies that are needed for a better understanding of the snakebites caused by this snake.

Eugenia section Phyllocalyx, a mainly Brazilian Atlantic Forest group of 16 species, is revised based on a study of over 2000 plant collections. The relationships of Eugenia sect. Phyllocalyx to other sections in Eugenia are discussed. All species are described and comments about geographic distribution and morphology are provided. An identification key and notes about its conservation status are also presented. Lectotypes are chosen for six species and second-step lectotypification is proposed for two species.

Two new species, Phyllanthus itamarajuensis and P. tuberculatus (Phyllanthaceae), currently restricted to the Atlantic Forest of Bahia State, Brazil, are described and illustrated. Phyllanthus itamarajuensis is distinguished by having long styles (2–2.2 mm long) associated with subshrubby habit, discretely asymmetrical basal leaves, and anthers with vertical dehiscence. Phyllanthus tuberculatus is characterized by glabrous leaves, a long pistillate pedicel (18–20 mm long), flowers of both sexes 5-merous, disk of the staminate flowers with five obtriangular segments with tuberculated surfaces, each being separated by a deep recess, and each with a central pore, anthers with non-divergent thecae, and a patelliform pistillate disk. The systematic position of both new species is discussed, and comments are provided on their morphological relationships, geographic distribution, conservation status, environmental preferences, and phenology.

Calling Activity

Data on geographic distribution and ecology are essential when defining the conservation status of a species. Herein, we present new information about the geographic distribution, habitat and advertisement call of Ischnocnema henselii, an endemic species of the southern Atlantic Forest. We conducted this study in forest fragments in the state of Santa Catarina, Southern Brazil, from January 2008 to November 2012. We recorded I. henselii in eight fragments over 100 ha in size, both inside and outside conservation units. We often observed less than 20 males in calling activity. The calling activity was daytime and nighttime, and more intense in the rain. We observed individuals perched on vegetation, on leaves or branches, on the leaf litter or under tree trunks. Duration of advertisement calls ranged from 14.71 ± 1.68 s (n = 11 calls) and interval between notes was 0.22 ± 0.13 s (n = 99 notes). We observed that the advertisement calls had a feature that we call "alternating modulation" in the amplitude of the notes. We suggest that further bioacoustic studies should analyze the relevance of this alternating modulation, to understand its role in communication. Although I. henselii is a habitat specialist, it is currently considered a common species, classified as Least Concern by Brazilian and IUCN lists. In the region studied, characterized by small and isolated remnants of the Atlantic Forest, I. henselii is not an abundant species and its spatial distribution is always associated with wet forest fragments. The increasing degradation of forest remnants in this region causes microclimatic and structural changes that may compromise the permanence of strictly forest and moisture-dependent species for reproduction, such as I. henselii.

Inga (Fabaceae, mimosoid clade) is an important genus in the Atlantic Forest of Brazil where there are 44 species, 60% of which are endemic. In this work, we describe two new species of Inga (I. teresensis and I. tripa) from the Atlantic Forest and provide identification keys to the species of sections Vulpinae and Leptinga in the biome. Illustrations and comments about the geographic distribution, conservation status, phenology, etymology, and taxonomy of the new species are also included. Inga teresensis is only known from the state of Espírito Santo and is categorized as Critically Endangered (CR). Inga tripa occurs in coastal areas of the states of Bahia, Paraíba, Pernambuco, and Sergipe and is categorized as Learn Concern (LC).

A New Species

Abstract—Merostachys delicatula, a new species recorded thus far only from the montane Atlantic forest of southern Bahia, is described and illustrated here. Comments on its taxonomy, distribution, habitat, and phenology are presented. Among the narrow-leaved congeners occurring in Bahia, the new species is most similar to M. leptophylla. It is distinguished by having internodes glabrous to scabrous (vs. glabrous in M. leptophylla); internodes with an infranodal band of trichomes (vs. absent); culm leaf sheaths abaxially scabrous (vs. glabrous); upper glumes 1.2‐2.1 mm wide (vs. 3.5‐4 mm); anthecia dull (vs. shiny); lemmas 1.5‐2.7 mm wide, abaxially pubescent (vs. ca. 4 mm, glabrous); and paleas 1.2‐2.3 mm wide (vs. ca. 4 mm). We also provide an assessment of the conservation status of the new species and a geographic distribution map for both species.

Drepanolejeunea pinnatiloba Schiffn. (Lejeuneaceae) has only been collected once in Brazil, from a single population in the Atlantic Forest in southern Bahia state. Seventeen years later, we report the second record of D. pinnatiloba. This new record is from the Una Biological Reserve, also in southern Bahia. We discuss the geographic distribution and evaluate conservation status of this species for Brazil and the Neotropical region.

Sarcoglanidinae and Glanapteryginae catfishes are among the most unusual elements of the Neotropical freshwater fish fauna. Microcambeva ribeirae, M. barbata and M. draco are miniaturized Sarcoglanidinae known to occur in sandy microhabitats in drainages of the Brazilian Atlantic Forest. Due to their specific habitats, specimens of Microcambeva are rare in fish collections, and new records are considered noteworthy to warrant report. Recently, specimens of this genus were newly found in the Rio Doce basin in Minas Gerais and Espírito Santo States. Such new records expand the known geographic distribution of Microcambeva. Further records of Microcambeva for Rio Peruípe in south Bahia State are also reported. Comments on the distribution of Microcambeva species along the Atlantic Forest coastal basins and suggestions on its conservation status are also offered.
