The diversity of dung beetles is still underestimated in northeastern Brazil. Recent collections have revealed new records of the following species: Canthon histrio (Lepeletier de Saint-Fargeau & Audinet-Serville, 1828), Coprophanaeus acrisius (MacLeay, 1819), Coprophanaeus dardanus (MacLeay, 1819), Deltochilum alpercata Silva et al., 2015, Deltochilum brasiliense (Castelnau, 1840), Dichotomius gilletti Valois et al., 2017, Dichotomius iannuzziae Valois et al., 2017, Eurysternus calligrammus Dalman, 1824, Eurysternus parallelus Castelnau, 1840, Oxysternon silenus Castelnau, 1840, and Phanaeus splendidulus (Fabricius, 1781). These records are discussed in light of the known biogeography of each species.

ABSTRACT Our goals were to determine whether the pattern of geographical distribution of dung beetles in the Brazilian Atlantic Forest (BAF), Southeast Brazil, supports the identification of the areas of endemism in this biome, how the number and boundaries of the areas of endemism vary with the spatial scale used in the analysis, if the areas of endemism identified here are consistent with previous proposals described in the literature. We used the analysis of endemicity (NDM) on the distributional patterns of 198 species and subspecies of dung beetles in order to identify areas of endemism into grids of 0.25°x0.25°, 0.5°x0.5° and 1°x1°. A total of 15 consensus areas (CA) were identified with the different grid sizes employed (two of 0.25°, three of 0.5° and 10 of 1°). Our results support the assumptions about the influence of the grid size, since a smaller number of CA were identified for the 0.25° grids (02 CA), whereas by increasing the size of the units, there was an increase in the number of the areas of endemism (10 CA of 1°). Despite different levels of geographical congruence, the areas of endemism located in the BAF described elsewhere are corroborate, all or part of them. The overlap of these CA allowed the definition of three generalized areas of endemism: Southeast, Central and Southwest. These generalized areas encompassed habitats with great environmental variety, potentially influencing the levels of endemism of species of dung beetles. Furthermore, they were corroborated by other areas of endemism described in the literature, allowing us to argue that processes forming these regions have influenced dung beetle species as described for other groups of organisms.

The Bromeliaceae Flora for the state of Rio Grande do Norte, Northeastern Brazil, is presented, based on extensive fieldwork, morphological analyses using herbarium and freshly collected material, and specialized literature. Twenty-six species of bromeliads were recorded in Rio Grande do Norte, distributed in ten genera and in three subfamilies. Bromelioideae was the richest subfamily (eight genera/14 species), followed by Tillandsioideae (one genus/12 species), and Pitcairnioideae (one genus/one species). Aechmea mertensii, Hohenbergia horrida and Tillandsia tenuifolia are new records for Rio Grande do Norte. Eight species (31%) are restricted to the Eastern portion of the state, in the Atlantic Forest. Caatinga dry woodlands harbor 18 species, with remarkable presence of Bromelia laciniosa, Encholirium spectabile, Tillandsia recurvata and T. streptocarpa, the four most widely distributed taxa. We discuss problems related to unclear taxonomic circumscriptions of species or diverging information between authors, more expressively in Hohenbergia, but also in Aechmea, Cryptanthus and Tillandsia. The data presented here might contribute to better understand the morphological variation of these taxa and suggest additional research on their taxonomy. Morphological descriptions, general comments, a map, photo plates and an identification key for all taxa are provided.

Two species of hubbardiid microwhipscorpions (Schizomida: Hubbardiidae) are recorded from the Brazilian Atlantic Forest. Rowlandius linsduarteae sp. nov. is described and illustrated based on specimens from Mata do Buraquinho forest reserve, João Pessoa, state of Paraíba, northeastern Brazil. This species is apparently related to Rowlandius sul Cokendolpher & Reddell 2000, the only species of the genus known from continental South America, and represents new evidence of a biogeographic relationship between Amazonia and the northeastern Brazilian Atlantic Forest. Stenochrus portoricensis Chamberlin, a widely distributed species, is newly recorded from the states of São Paulo and Bahia, respectively, in southeastern and northeastern Brazil. The latter record refers to several female specimens associated with abandoned arboreal termite nests in a cocoa plantation.

There are currently 760 reptile species known in Brazil, from which about 70 are amphisbaenians with 25 species recorded in the Brazilian northeast (Vanzolini 2002; Gomes & Maciel 2012; Costa & Bérnils, 2014; Roberto et al., 2014). Leposternon polystegum Duméril, is a widespread species distributed in the Amazon, Atlantic Forest, Cerrado, and Caatinga biomes (Porto et al., 2000; Ribeiro et al., 2011). The diet is composed mainly by ants, termites, and coleopteran larvae (Barros-Filho & Valverde, 1996; Gomes et al., 2009).

Melanoides tuberculata (Müller, 1774) was recorded during field surveys of the malacofauna of Território Vale do Guaribas in Piauí state, northeastern Brazil. Individuals were observed every month (June 2017–September 2018) in both lotic and lentic habitats. Considering that M. tuberculata has high reproductive and adaptative capacities besides being an intermediate host of digenetic trematodes, this invasive species is expected to be a threat to native biodiversity. Furthermore, it may become a serious environmental problem considering the multiple uses of the water bodies where it lives.

We present new records of Hoary Fox, Lycalopex vetulus (Lund, 1842), and Pantanal Cat, Leopardus braccatus Cope, 1889, from a Cerrado-Caatinga-Atlantic Forest ecotone, Brazil. Records are based on three roadkilled specimens (two Hoary Foxes and one Pantanal Cat) from Vitória da Conquista, southern Bahia. Although highly anthropized, the region still holds a mosaic of Cerrado savannas and Caatinga seasonally dry forests. Our records expand the distribution of both species eastwards to southern Bahia and suggest that Leopardus braccatus may occur marginally in the Caatinga.

AbstractDung beetles (Coleoptera: Scarabaeinae) mediate many ecological functions that are important to maintain the ecosystem functioning of terrestrial environments. Although a large amount of literature explores the dung beetle-mediated ecological processes, little is known about the individual contribution from distinct species. Here, we aimed to examine the intra and interspecific variations in dung burial rates performed by two roller dung beetle species (Canthon smaragdulus Fabricius, 1781 and Canthon sulcatus Castelnau, 1840). Furthermore, we evaluated the relationship between dung beetle biomass and dung burial rates. We set up a laboratorial experiment with three treatments (two males, two females, and a couple) and 10 replicates per treatment for each dung beetle species, and dung burial rates were measured after exposing 100 g of mixed pig and human excrement for 48 hours. Our results demonstrate that dung burial rates of males, females, and couples within each species do not differ. However, C. smaragdulus individuals performed a larger dung burial than C. sulcatus individuals did. In addition, we found no effect of individual biomass on the amount of dung burial on intra and interspecific levels. These findings highlight the need for further research considering that distinct species, even from the same genus, may perform different rates of ecological processes, as well as about the importance for considering the beetle biomass when measuring their ecological functions. We call for studies to fill in the knowledge gap about the individual species’ contribution to the maintenance of different dung beetle-mediated ecological processes.

The subfamily Desmodontinae encompasses the only mammals known to feed exclusively on the blood of other vertebrates. This study provides records of the desmodontine bat Diphylla ecaudata from a major gap in its known distribution in northeastern Brazil. Specimens were captured at five localities, all associated with caves. Two of these sites are located in the state of Sergipe, two in Bahia, and one in Ceará. The record of D. ecaudata from Ceará is the first for this state.
