Rhipsalis Gaertner (1788: 138) belongs to Cactaceae Juss., which is among the major taxonomic groups including the highest numbers of threatened species in the world (Goettsch et al. 2015). The center of diversity and endemism of this genus is in the Atlantic Forest in Brazil, a world hotspot of biodiversity (Myers et al. 2000). This forests harbors 5% of all flowering plants species on the planet (Stehmann et al. 2009), including a high diversity of vascular epiphytes. Cactaceae is the sixth most expressive family in terms of number of epiphytes in the Atlantic Forest (2.2% of all vascular epiphyte species at the domain; Freitas et al. 2016) and Rhipsalis is the largest genus of epiphytic cacti (40 species according to Calvente 2012), highlighting the importance of this genus amongst the global epiphytic flora.

Abstract Edge effects are ubiquitous landscape processes influencing over 70% of forest cover worldwide. However, little is known about how edge effects influence the vertical stratification of communities in forest fragments. We combined a spatially implicit and a spatially explicit approach to quantify the magnitude and extent of edge effects on canopy and understorey epiphytic plants in the Brazilian Atlantic Forest. Within the human-modified landscape, species richness, species abundance and community composition remained practically unchanged along the interior-edge gradient, pointing to severe biotic homogenisation at all strata. This is because the extent of edge effects reached at least 500 m, potentially leaving just 0.24% of the studied landscape unaffected by edges. We extrapolated our findings to the entire Atlantic Forest and found that just 19.4% of the total existing area is likely unaffected by edge effects and provide suitable habitat conditions for forest-dependent epiphytes. Our results suggest that the resources provided by the current forest cover might be insufficient to support the future of epiphyte communities. Preserving large continuous ‘intact’ forests is probably the only effective conservation strategy for vascular epiphytes.

Abstract The diversity of montane environments is dictated by a variety of environmental conditions. Parque Estadual do Ibitipoca is located in the Serra da Mantiqueira, between ~1,000-1,800 m, and harbors approximately 300 ha of cloud forests. The composition of vascular epiphytes was determined by analyzing data from expeditions conducted between July 2014 and July 2015, and specimens deposited at herbaria. The 224 species were distributed into 82 genera of which Pleurothallis s.l. was the richest (13 spp.) and 23 families of which Orchidaceae was the richest (87 spp.). This richness corresponds to approximately 9.5% of the vascular epiphytic flora of the Atlantic Forest concentrated in an area that comprises 0.00085% of this phytogeographic domain, which represents one of the largest diversities ever sampled in the Brazilian Atlantic Forest. This fact is more relevant given that 13 species are threatened at the country level and 23 at the state level.

Three new species of Otostigmus Porat, 1876 from Brazilian Atlantic Forest are described. Otostigmus beckeri sp. n. andO. lanceolatus sp. n. are described from the state of Bahia and O. giupponii sp. n. from the state of Espírito Santo. InBrazil, the otostigmine scolopendrid genus Otostigmus comprises 22 species. A summary of Brazilian Otostigmus speciesis presented with new distribution records, taxonomic remarks when appropriate and an identification key. Otostigmus sul-catus Meinert, 1886 is recorded for the first time from Brazil; the Andean Otostigmus silvestrii Kraepelin 1903, previouslyrecorded from Brazil, is here considered not to be present in this country. Eight nominal species are regarded here as newsynonyms. Five of them—Otostigmus pradoi Bücherl, 1939, O. longistigma Bücherl, 1939, O. longipes Bücherl, 1939,O. langei Bücherl, 1946 and O. dentifusus Bücherl, 1946—are based on females of O. tibialis Brölemann, 1902. O. latipesBücherl, 1954 is conspecific with and is considered a junior synonym of O. sulcatus Meinert, 1886; O. limbatus diminutusBücherl, 1946 is a junior synonym of O. limbatus Meinert, 1886 and O. fossulatus Attems, 1928 is a junior synonym of O. goeldii Brölemann, 1898. A lectotype is designated for O. goeldii.

Jurasaidae are a family of neotenic elateroid beetles which was described recently from the Brazilian Atlantic Forest biodiversity hotspot based on three species in two genera. All life stages live in the soil, including the larviform females, and only adult males are able to fly. Here, we report the discovery of two new species, Jurasai miraculum sp. nov. and J. vanini sp. nov., and a new, morphologically remarkable population of J. digitusdei Rosa et al., 2020. Our discovery sheds further light on the diversity and biogeography of the group. Most species of Jurasaidae are known from the rainforest remnants of the Atlantic Forest, but here for the first time we report a jurasaid species from the relatively drier Atlantic Forest/Caatinga transitional zone. Considering our recent findings, minute body size and cryptic lifestyle of all jurasaids, together with potentially high numbers of yet undescribed species of this family from the Atlantic Forest and possibly also other surrounding ecoregions, we call for both field research in potentially suitable localities as well as for a detailed investigation of a massive amount of already collected but still unprocessed materials deposited in a number of Brazilian institutes, laboratories and collections.
