“…The studies of Archangelsky et al (2009), Merritt andCummins (1996), Bertrand (1972) and Leech and Chandler (1956) are noteworthy for quoting various genera found in Brazil. In recent years, studies related to taxonomy of water beetles (Spangler, 1990;Costa et al, 1996;Vanin and Costa, 2001;Benetti et al, 2006;Ferreira Junior et al, 2006;Passos et al, 2007;Braga and Ferreira Junior, 2009;Fernandes et al, 2010;Queney, 2010) and ecology (Benetti and Hamada, 2003;Passos et al, 2003a, b;Segura et al, 2007a, b) are increasing. However, because of the incipient stage of knowledge of the water beetles in the country, further studies are needed.…”

Inventories provide information on the state of biodiversity at a site or for a geographic region. Species inventories are the basis for systematic study and critical to ecology, biogeography and identification of biological indicators and key species. They also provide key information for assessments of environmental change, for natural resource conservation or recovery of degraded ecosystems. Thus, inventories play a key role in planning strategies for conservation and sustainable use. This study aimed to inventory the fauna of water beetles, larvae and adults, in two mountainous regions in the state of São Paulo, in Serra da Mantiqueira (Parque Estadual de Campos do Jordão and Pindamonhangaba region) and in Serra do Mar (Santa Virgínia and Picinguaba Divisions) as well as to generate information about the habitats used by the different genera recorded. Specimens were collected in lotic and lentic systems, between the years 2005 to 2010. In total 14,492 specimens were collected and 16 families and 50 genera of Coleoptera were identified. This study in mountainous regions showed a significant portion of the faunal composition of South America and the state of São Paulo. The composition of the fauna, in terms of richness and abundance by family, indicated the predominance of Elmidae, followed by Hydrophilidae and Dytiscidae. Despite the diversity found, the results of estimated richness indicated the need for additional sampling effort for both regions, since the curves of estimated richness did not reach an asymptote, suggesting that new species can be found in future surveys.

., SPIES, M.R., PIRES, M.M. Diversity and distribution of riffle beetle assemblages (Coleoptera, Elmidae) in montane rivers of Southern Brazil. Biota http://dx.doi.org/10.1590/1676-060320140615183046Abstract: The diversity and spatio-temporal distribution of Elmidae (Coleoptera) assemblages in montane rivers and streams of southernmost Brazil (Rio Grande do Sul state) were studied. Six genera were found, represented mostly by larval specimens. Austrolimnius and Macrelmis are new occurrences in the region. Assemblages' genera composition and dominance were related to the presence of the macrophyte Podostemum. Also, water temperature and stream depth and velocity were the most important drivers related to the assemblages' distribution. Richness and abundance were positively related to high water velocity and negatively to stream depth. Temporal patterns were detected especially in assemblage abundance, yet a slight pattern in richness was also observed. The seasonal structure was related to warm temperatures, but temporal distribution of Elmidae assemblages appears to be related to the dominant genera life cycles. The studied area shows an overall Elmidae richness similar to that found in some tropical areas and the role of mountainous environments in sustaining high rates of regional diversity in the Neotropics is stated. Keywords: aquatic insects, streams, Neotropical region.

“…Although riffle beetles are recognized in the scientific literature as effective bioindicators of water quality (Brown 1972a;Garcia-Criado & Fernández-Aláez 2001;Elliot 2008), there is a large limitation of knowledge about the family in Brazil, as well as information on biology and its importance in dynamics of aquatic ecosystems (Vanin & Ide 2002;Passos et al 2007).…”

ABSTRACT. A taxonomic key for the genera of Elmidae (Coleoptera, Byrrhoidea) occurring in Goiás State, Brazil, including new records and distributional notes. Despite their great diversity and high abundance in Neotropical aquatic environments, the fauna of Elmidae remains practically unknown in some areas and even entire biomes in this region. In this work we bring, for the first time, faunistic data for the Elmidae of central Brazil. The aim of this work was to inventory the Elmidae fauna in central, southwestern and southeastern Goiás State, Brazil and to produce a taxonomic key, at genus level, for adults from the studied region. The taxonomic key presented herein offers means for the identification of all the 13 genera known to occur in Goiás, 11 of them being new records for the State. Moreover, the number of named species registered for Goiás increased from one to nine.
