Abstract An inventory of Odonata was carried out in the southern half of the state of Rio Grande do Sul, Brazil, in the Pampa biome. Originally, this biogeographical region was covered mostly by open fields and grassland, with sections of higher vegetation surrounding water bodies and rocky hills. Today the landscape is fragmented due to agricultural activities, mainly cattle farming, rice crops and forest plantations. Our survey was conducted in three municipalities from this region, between March 2015 and April 2016. Aiming at a general overview of the species composition, our sampling sites were selected on a wide basis, including lakes, bogs, temporary water bodies, small streams and river sections. Eighty two species of Odonata were collected comprising 40 genera and seven families. The dominant families were Libellulidae (56,1%), Coenagrionidae (24,5%) and Aeshnidae (7,3%). We found a diverse odonate assemblage, adding 19 new species records for the state of Rio Grande do Sul.

Rio Grande do Sul (RS) is the southernmost state in Brazil and includes areas within the Pampa and Atlantic Forest biomes. The semiaquatic bugs (Hemiptera, Heteroptera, Gerromorpha) from RS are poorly known, with only 14 previously recorded species. We carried out two expeditions in this state, in 2002 and 2019, across 19 municipalities. Here, we provide new records for 19 species, of which 13 are recorded for the first time from the state, five have their distributions expanded, and one is recorded again from a same locality previously reported in the literature. Furthermore, 13 species were collected for the first time in the Pampa biome and one in the Atlantic Forest.

The growth of humankind has brought with it several environmental problems that have worsened over time, including the loss of insect biodiversity. The Odonata order have been indicated by several authors as relevant bioindicators for assessing and monitoring environmental conditions of specific locations. The main objective of this study was to conduct an inventory of the Odonata diversity in the Pampa Biome, of the Southern region of the state of Rio Grande do Sul, Brazil. The species survey was conducted between November 2014 and October 2015. Adult insects were collected in Capão do Leão, Pelotas and Rio Grande cities. Each location was visited nine times, totalizing 54 samplings. Entomological nets were used for capturing adult insects, which were then kept in entomological envelopes. The identification of the specimens was carried out with taxonomic keys of Lencioni and Heckman. In addition, Chao-1, the Shannon-Wiener and Jackknife indexes were associated with the sampling areas. During the species survey a total of 2 680 Odonata specimens were collected, representing 45 species encompassed in 22 genera and six families. The Libellulidae and Coenagrionidae families were registered in 60 and 30 % of the specimens sampled, followed of the Aeshnidae, Calopterygidae, Gomphidae and Lestidae, of reduced occurrence. The genera Erythrodiplax, Micrathyria and Ischnura were found at least once in all the visited sites. The study resulted in the registration for the first time of the following species: Progomphus complicatus Selys, Lestes minutus Selys, Homeoura ambigua Ris, and Tauriphila xiphea Ris. These species were not previously reported in any Odonata study of the Brazilian state of Rio Grande do Sul. In regard to Odonata diversity in the Southern region of Rio Grande do Sul, Libellulidae and Coenagrionidae are the families more abundants. Erythrodiplax and Micrathyria are the most common genera. Miathyria marcella represented 9.6 % of all collected libellulidae and was the most abundant specie. Capão do Leão has the largest species diversity (wealth), the largest number of collected specimens and more diversity than Pelotas and Rio Grande. However, the results showed that the Odonatofauna in the State are still little known, and new studies are needed to better describe this group in other regions.

ABSTRACT: The diversity of edaphic mites in Brazilian natural environments is little known, especially in the Pampa biome, in southern region of Brazil. The objective of this study was to evaluate the diversity and abundance of edaphic fauna of mesostigmatid mites in a region of the Pampa biome of the state of Rio Grande do Sul. Soil samples were collected in the municipality of Aceguá, in 2012 and 2013. Mites were extracted using Berlese-Tullgren modified funnels. In total, 1900 mesostigmatid mites were collected, representing 44 species from 23 genera and 10 families. The most abundant families were Rhodacaridae, Ologamasidae and Laelapidae, with respectively 903, 578 and 214 specimens, corresponding respectively to 47.5, 30.4 and 11.3% of the Mesostigmata collected. Laelapidae was the most diverse family, being represented by 22 species. The remaining families were each represented by 1-5 species. Gaeolaelaps (Laelapidae) was the most diverse genus, with 14 species. Rhodacaridae was represented by a single species, Binodacarus aceguaensis Duarte, Castilho, Cunha & Moraes, representing 47.5% of the mesostigmatids. Ologamasidae was represented by four species, with Neogamasellevans sp. corresponding to the second most abundant species, representing 27.5% of the mesostigmatids. Further analysis of the data, in terms of mite identification to species level and the potential use of the mites collected for applied biological control are needed.

In order to characterize the epigeic myrmecofauna in fields and vineyards in the physiographic region of Campanha, located in the Pampa biome, state of Rio Grande do Sul, inventories were conducted on three farms. On each farm, samples were collected in three environments: the rows in the vineyards, the spaces between rows in the vineyards, and the adjacent areas, with vegetation similar to that which preceded the establishment of crops. In each environment, 20 points were sampled using pitfall traps. We collected 72 species distributed among 24 genera and seven subfamilies. The study provides the first inventory of the ant fauna in the region, contributing with new records for the state of Rio Grande do Sul and for Brazil. It is hoped that this inventory will stimulate further studies on the biodiversity of this biome that is still poorly known.

Eriophyoid Mites

Four new species of eriophyoid mites (Acari: Trombidiformes: Eriophyoidea) were collected from native plant species from Pampa biome, in the state of Rio Grande do Sul, Brazil, and are described and illustrated herein. They have been named: Aculus pampae sp. nov. on Elephantopus mollis Kunth (Asteraceae); Costarectus lanceatus sp. nov. on Sebastiania brasiliensis Spreng. (Euphorbiaceae); Dichopelmus sigfeminae sp. nov. and Rhynacus symflori sp. nov. both on Symplocos uniflora (Pohl) Benth. (Symplocaceae). All new species appeared to be vagrants and no apparent symptom was associated to them.

Terrestrial Isopods were sampled in four protected Atlantic Forest areas located in Serra do Mar, state of São Paulo, southeastern Brazil. A total of 2,217 individuals of six species (Atlantoscia sp., Benthana werneri, Pseudodiploexochus tabularis, Pudeoniscus obscurus, Styloniscus spinosus and Trichorhina sp.) were captured in pitfall traps. The exotic species S. spinosus is recorded for the first time for the Americas. Another introduced species, P. tabularis, previously recorded only from the state of Rio Grande do Sul, had its geographic distribution extended to the state of São Paulo. The most abundant isopods in this study belong to an undescribed species of Atlantoscia.
