Riparian forests bordering open terrestrial environments may have three microhabitats differing in structure and conditions: a grassland/pasture-forest edge (GE), a forest interior (FI) and a river–forest edge. The influence of such edge effects and vegetation characteristics on spider diversity of riparian forests was evaluated in Southern Brazil. Four(More)
The distribution of beta diversity is shaped by factors linked to environmental and spatial control. The relative importance of both processes in structuring spider metacommunities has not yet been investigated in the Atlantic Forest. The variance explained by purely environmental, spatially structured environmental, and purely spatial components was(More)
Wetlands (e.g. ponds, meadows) can be found in many landscapes, playing an important role in maintaining regional biodiversity and supporting heterogeneous communities. Spiders are diversified predators that are highly influenced by changes in plant community structure, heterogeneous habitats sustain high spider diversity and abundance. We investigated the(More)
The theridiid genus Thymoites Keyserling, 1884 is distributed worldwide. Spiders of this genus are mainly known from the Neotropical Region, but are poorly studied in Brazil. In this paper nine new species of Thymoites are described from Brazil, one from the state of Alagoas: Thymoites murici n. sp.; two from São Paulo: T. bocaina n. sp., T. ilhabela n. sp.(More)
The genus Neonella Gertsch, 1936 contains 12 species with an exclusive New World distribution (World Spider Catalog 2015). The genus was proposed by Gertsch (1936) to include N. vinnula Gertsch, 1936 from Florida and Texas, USA. Remaining species were added by Galiano (1965, 1988, 1998) and, more recently, Edwards (2003), Ruiz & Brescovit (2004), and Ruiz(More)
Terrestrial diplopods are a diverse group of invertebrates with important ecosystem roles within soil communities, though information from the Neotropical Region is still scarce. The present study investigates the association between Diplopoda diversity and composition with vegetation structure, based on pitfall trap samples taken from three different(More)
The spider family Nesticidae includes 233 species in 13 genera and is distributed almost worldwide (World Spider Catalog, 2016). However, the family is still poorly known in the Neotropical Region. The genus Nesticus Thorell, 1869 comprises 132 species and seven subspecies and was described based on N. cellulanus (Clerck, 1757), from Europe (World Spider(More)
The theridiid genus Dipoena Thorell, 1869 is distributed worldwide. Dipoena are recognized by male with carapace often high, cylindrical, with grooves or depression on dorsum; carapace of female rarely modified, sometimes high. In this paper six new species of Dipoena are described from Brazil, one from the state of Mato Grosso do Sul: Dipoena bonitensis(More)
The araneid genus Larinia Simon currently includes 56 species, eleven of them with New World distribution (World Spider Catalog, 2016). North American species of the genus were revised first time by Levi (1975) and South American species by Harrod et al. (1991). According to these authors there are four species known from subtropical South America (Larinia(More)
Neocunaxoides promatae sp. nov., Bonzia flechtmanni sp. nov. and Dactyloscirus multiscutus sp. nov. are described from soil and leaf litter in Atlantic rainforest and Atlantic Araucaria forest in natural environments in São Francisco de Paula municipality, Rio Grande do Sul State, Brazil. In addition, the species Pulaeus quadrisolenidius Castro & Den Heyer(More)
