RESUMO

The present study evaluates the monophyly of Spintharinae with the inclusion of all ten genera listed under subfamily (Brunepisinus; Chrosiothes; Episinus; Janula; Moneta; Neoepisinus; Pycnoepisinus; Spintharus; Stemmops; and Thwaitesia) and establishes the internal relationship among the spintharines genera. We evaluated 107 morphological characters and included 59 species as terminal taxa, 13 of which are outgroups. The phylogenetic analysis under implied weight resulted in three most parsimonious trees with the same topology with six optimal K values (3.349, 4.025, 4.910, 6.117, 7.859, 10.598). The monophyly of the Spintharinae is supported by four synapomorphies, two of these are exclusive. Stemmops was found to be a sister group to the rest of Spintharinae. The genera Spintharus, Thwaitesia, and Chrosiothes constitute a group. A larger group is represented by Brunepisinus, Episinus, Moneta, Neopisinus, and Pycnoepisinus. The other large group includes species of Janula and some species of Episinus. The genus Episinus appears polyphyletic. We described seven new species of the Spintharinae genus Janula from Brazil. Sixteen species are transferred from Episinus to Janula. Males of Janula malachina and J. teresopolis are described for the first time. Episinus rio is synonymized with Janula bicorniger. We present new illustrations of the male and female of Janula nebulosa and J. salobrensis. The species Janula bicruciata and J. nebulosa are recorded for the first time from Bolivia and other new records are provided for the known species. Episinus albostriatus is transferred to Chrosiothes.

RESUMO

The spider genus Euryopis Menge, 1868 (Theridiidae) currently comprises 76 described species worldwide and only two described species from Brazil and none for Bolivia. In this paper four new species of Euryopis from Brazil and Bolivia are described and illustrated: Euryopis candiota n. sp.; Euryopis nasuta n. sp.; Euryopis catarinensis n. sp. all from Brazil and Euryopis boliviensis n. sp. from Bolivia. New records from Brazil are provided for E. camis Levi, 1963 and E. spinifera O. Pickard-Cambridge, 1895.

RESUMO

Abstract: This study aimed to present a list of the species of frugivorous butterflies occurring in Atlantic Forests, in the Conservation Units: National Forest of Chapecó (FLONA), Ecological Station of Mata Preta (ESEC) and State Park of Araucárias (PAEAR) and adjacent forest fragments, located in the western region of the state of Santa Catarina. Three samplings were conducted between December 2017 and March 2018, totaling 24 days of collection in each sampling area. Van Someren-Rydon traps were used to capture frugivorous butterflies. There were 4,231 frugivorous butterflies belonging to four subfamilies, 12 tribes and 49 species. In all, 37 species of frugivorous butterflies were sampled in FLONA and 29 in adjacent forest fragments. In ESEC, 29 species and 33 in adjacent forest fragments. In PAEAR, 33 species and 28 in adjacent forest fragments. Of the total species registered, 15 species are new records for the state of Santa Catarina and 11 are new records for the western region of the state. The most abundant species for FLONA were: Manataria hercyna (Hübner, 1821) and Hermeuptychia sp. In ESEC, were Hermeuptychia sp. and Yphthimoides ordinaria (Freitas, Kaminski & Mielke, 2012). In PAEAR, greater abundance of Forsterinaria quantius (Godart, 1824) and Eryphanes reevesii (Doubleday, 1849) were verified. For the adjacent forest fragments to Conservation Units, there was a greater abundance of Hermeuptychia sp., Moneuptychia soter (Butler, 1877), Morpho epistrophus (Fabricius, 1796) e Forsterinaria quantius (Godart, 1824). Satyrinae presented higher richness (S = 34) and abundance (90.58%) in all areas sampled. The rarefaction and extrapolation curves for the Conservation Units and adjacent forest fragments showed a greater rise in the FLONA and PAEAR sampling units and their adjacent forest fragments. The estimated sampling coverage for Conservation Unit and forest fragments was above 97%. The richness calculated through the Jackknife 1 estimator, for the FLONA and PAEAR samplings, presented a value of 50.75 and 37.09, respectively. The fauna of frugivorous butterflies from this region, first investigated in areas of Conservation Units, showed to be expressive and well represented in the Atlantic Forest Biome, indicating its potential as a refuge for biodiversity.

Satyrinae apresentou maior riqueza (S=34) e abundância (90,58%) de borboletas frugívoras em todas as áreas amostradas. As curvas de rarefação e extrapolação, para as Unidades de Conservação e fragmentos florestais adjacentes mostraram uma maior ascendência nas unidades amostrais da FLONA e PAEAR e seus fragmentos florestais adjacentes. A cobertura estimada de amostragem para as borboletas frugívoras, para as Unidades de Conservação e fragmentos florestais, ficou acima de 97%. A riqueza calculada através do estimador Jackknife 1, mostrou-se superior à riqueza observada, sendo que para as amostragens na FLONA e PAEAR, o estimador apresentou um valor de 50,75 e 37,09, respectivamente. A fauna de borboletas frugívoras da região, investigada pela primeira vez em áreas de Unidades de Conservação, mostrou-se bastante expressiva e bem representada no Bioma Mata Atlântica, indicando seu potencial como refúgio da biodiversidade.

RESUMO

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 bivittata Keyserling 1885; L. montecarlo (Levi, 1988); L. t-notata (Tullgren, 1905); L. tucuman Harrod, Levi & Leibensperger, 1991) and also four species known from tropical South America (L. ambo Harrod, Levi & Leibensperger, 1991; L. directa (Hentz, 1847); L. lampa Harrod, Levi & Leibensperger, 1991; L. neblina Harrod, Levi & Leibensperger, 1991). According to Buckup et al. (2010) a total of 209 species of Araneidae are recorded for state of Rio Grande do Sul, including the three species L. bivittata, L. montecarlo and L. t-notata.

RESUMO

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 Catalog, 2016). Meridional South American species of Nesticus were revised by Ott & Lise (2002). More recently, Faleiro & Santos (2011) described a new species from the state of Minas Gerais, Brazil and Torres et al. (2016) a new species from the province of Salta, Argentina. Nowadays, Nesticus is represented by six species in Brazil: Nesticus brasiliensis Brignoli, 1979; Nesticus brignolii Ott & Lise, 2002; Nesticus calilegua Ott & Lise, 2002; Nesticus ivone Faleiro & Santos, 2011; Nesticus potreiro Ott & Lise, 2002 and Nesticus taim Ott & Lise, 2002 (World Spider Catalog 2016).
