“…The diversity patterns concerning the families representing EPT in the Neotropics were maintained in relation to studies conducted in other regions of the country (Bispo and Oliveira, 2007;Righi-Cavallaro et al, 2010). The Plecoptera is represented by six families in the Neotropics (Stark et al, 2009), but only two (Gripopterygidae and Perlidae) occur in Brazil (Froehlich, 2011); both recorded in this study. Fourteen families of Ephemeroptera are recorded in the Neotropics, ten of them in Brazil (Salles et al, 2004).…”

AIMS: In this study, the diversity of Ephemeroptera, Plecoptera, Trichoptera and Coleoptera communities was surveyed in the Toropi River basin, a watershed localized in a slope region, in southernmost Brazil. The influence of some local abiotic factors on the most common genera was also analyzed. METHODS: Samplings were conducted at 40 sites in 1st-4th order streams, along a short elevation gradient (70-500 m), with a Surber sampler. Water physico-chemical factors, as well as substrate type, were obtained at each site. RESULTS: At all, 5,320 specimens were collected, belonging to 18 families and 52 genera. The caddisflies Austrotinodes and Celaenotrichia, and an undescribed Elmidae, Genus M, are new records for the region. The caddisfly Smicridea was the most frequent genus in the study area. The mayflies Camelobaetidius, Paracloeodes and Americabaetis were influenced by stream order. Smicridea was related to air temperature, while the mayfly Thraulodes was influenced by high levels of electrical conductivity. CONCLUSIONS: The high diversity found in the study area, compared to other Brazilian regions, reflects the environmental heterogeneity in the region. These data show that hydrographic basins in slope areas from extreme Southern Brazil sustain high levels of diversity of aquatic insect communities.

“…In each stream, the largest variety of mesohabitats were identified in situ and aquatic invertebrates were collected in three replicate samples with a Surber and three replicate samples of twenty seconds with a D net (both equipment with a 250μm mesh). Taxonomic identification was made up to the genus level with the aid of taxonomic keys and specialists (Merritt & Cummins, 1996;Epler, 2001;Benetti et al, 2003;Heckman, 2006Heckman, , 2008Lecci & Froehlich, 2007;Mariano & Froehlich, 2007;Michat et al, 2008;Dominguez & Fernández, 2009;Mugnai et al, 2010;Ramírez, 2010;Springer, 2010;Froehlich, 2011;Trivinho-Strixino, 2011;Braun et al, 2014;Hamada et al, 2014). Specimens that presented loss of morphological structures were identified up to the lowest possible taxonomic level.…”

Pollution tolerance, flight capacity and natural history explain metacommunity structure in high-altitude stream insects

et al. 2020

Aim To test how different taxonomic and functional groups of aquatic insects from high-altitude streams respond to environmental and spatial gradients at multiple scales in Southeast of Brazil. Methods Specimens were collected in 26 high-altitude streams distributed over a gradient of previously defined environmental quality. The taxonomic identification was made at the genus level and the functional classification was based on traits of flight capacity and pollution tolerance compiled from specific literature. We obtained local in situ data (limnological, sediments, and organic matter), as well as calculated land use at the riparian and drainage basin scale. A variation partitioning approach was used to explain species composition based on different response matrices deconstructed by both taxonomic groups and functional traits. The explanatory matrices encompassed environmental variables at three spatial scales and spatial variables extracted from Principal Components of Neighbor Matrices analysis. A linear model was applied to verify the possible correlation between spatial and environmental components. Results The contribution of the spatial and environmental components varied strongly between taxonomic and functional groups. For taxonomic groups, the pure environmental component was more important for Odonata and Trichoptera, while spatial variables were more important for Diptera (non-Chironomidae) and Chironomidae, Coleoptera, Ephemeroptera, Plecoptera and Megaloptera. The sensitive groups with good flight capacity showed a greater environmental signature while the tolerant groups with low flight capacity had a greater spatial signature. Moreover, the important variables for explaining community variation were from different spatial scale (local, riparian and watershed) depending either on the analyzed taxonomic or on functional groups. However, a general effect of forests was found in several groups. Conclusions It is necessary to consider the joint effect of evolutionary natural history of groups, as well as their functional traits in the structuring of metacommunities, since only taxonomic resolutions may not be sufficient to detect assembly processes at multiple spatial scales.

“…5). Until 2011 a total of 26 species of Gripopterygidae were registered in São Paulo (Froehlich, 2011). Most of these records are due to the efforts of Prof. Dr. Claudio G. Froehlich and other researchers involved in programs such as the BIOTA/FAPESP, that since 1999 has funding studies on fauna of São Paulo State.…”

Gripopterygidae (Plecoptera) includes genera and about 320 species, of them recorded from South America. Although recent molecular analysis does not support all subfamilies, the family is traditionally divided into five subfamilies, being Gripopteryginae endemic to South America, comprising 15 genera and about 80 species. Among the genera of this subfamily, the Neotropical Paragripopteryx Enderlein currently comprises 14 species. The genus occurs along the coastal Brazilian mountains, from northeast of Bahia State to Rio Grande do Sul State, Brazil, while two species are restricted to Uruguay. According to traditional studies, the intergeneric relationships in Gripopterygidae and the delimitation of the current South American subfamilies (including Gripopteryginae) need to be reviewed. Considering Paragripopteryx, the genus has been defined based only on combination of morphological characters, without synapomorphies, therefore, the genus needs to be better delimited. As an attempt to understand the phylogenetic relationships in these two taxa (Gripopteryginae and Paragripopteryx), we performed two cladistic analyses based on morphological characters. As regards the Gripopteryginae, we used a dataset with 51 characters and 43 terminal taxa. In the case of Paragripopteryx, we used a dataset with 39 characters and 31 terminal taxa. We used Parsimony analysis with equal and implied weighting of characters (varying k-values: k = 3-15) and considered all characters as nonadditive. In the first approach, we recovered Neopentura semifusca outside the delimitation of Gripopteryginae and closer to Antarctoperlinae. Based on our results and considering the previous morphological analysis, we reclassified this genus in Antarctoperlinae. All other Gripopteryginae remained nested in a clade as sister of Australian Leptoperlinae, being this clade supported by a single synapomorphy: the sixth anal vein fused to wing margin in hind wings. Gripopteryginae taxa were supported by three synapomorphies: the CuA vein forked in forewings; distal margin of central sclerite in T10 protruding/coming out; and the absence of posterior sclerite in T10. Considering the analyses for Paragripopteryx, P. munoai was recovered outside the current delimitation of Paragripopteryx. For this reason, a new genus in Gripopteryginae is proposed to house this species. All other Paragripopteryx species remained nested in a clade supported by a single synapomorphy: the presence of pterostigmatic crossvein in forewings. In parallel to the phylogenetic study, we performed a revision of Paragripopteryx with the description of three new species and synonymy of P. crassila with P. klapaleki. Finally, we present an updated list of Brazilian Gripopterygidae with some notes, and the description of a new species of Tupiperla.
