We present in the following an Errata Corrigenda for Abrantes et al. (2010) Table 2 and general counting. Furthermore, we include all additional records for Brazilian Collembola during 2010 and 2011 as an update for the species list. The update was made following the same methodology and criteria as Culik and Zeppelini (2003), and Abrantes et al. (2010). All data will fit the same table marked differently to be recognized at glance. The references presented here are restricted to the citations concerning the update only; therefore the references presented in Culik and Zeppelini (2003), and Abrantes et al. (2010) will not be repeated.
The current total number of species found in Brazil is 270, distributed in 19 families and 92 genera, an increase of 71 species and 12 genera in the last 6 years. The greatest known diversity is found in Rio de Janeiro (132 species), Amazonas (56), Espírito Santo (30) and São Paulo (28), while there are no record to seven Brazilian states (Acre, Alagoas, Distrito Federal, Goiás, Rio Grande do Norte, Roraima and Tocantins). Distribution of the records clearly defines the areas that urge investments in scientific research and taxonomic survey and reflects the concentration of information in those centers that host the few specialists in Collembola, currently working in Brazil.
São registradas novas espécies e novas ocorrências de Collembola Poduromorpha no litoral de Maricá, estado do Rio de Janeiro. Das 20 espécies coletadas, quatro são descritas e ilustradas: Mesaphorura maricaensis sp. nov. (Onychiuridae); Brachystomella ceciliae sp. nov. (Brachystomellidae); Arlesia intermedia sp. nov. e Micranurida fluminensis sp. nov. (Neanuridae). Os gêneros Doutnacia Rusek, 1974 e Micranurida Börner, 1901 e as espécies Xenylla maritima Tullberg, 1869, Acherontiella globulata Thibaud & Massoud, 1979, Onychiurus cf. mariapetrae Thibaud, 1993, Friesea reducta Denis, 1931, Pseudachorutes difficilis Denis, 1931 são registrados pela primeira vez para o Brasil. O elevado número de espécies e o registro de 16 novas ocorrências nesta área mostram a escassez de estudos taxonômicos e a elevada biodiversidade de Poduromorpha na restinga.
Furculanurida tropicalia sp. nov., is described from leaf litter of the Atlantic forest of Southeast Brazil. It is characterized as being the first species of the genus that possess 8+8 eyes. New diagnosis and remarks on the genus and the species of Furculanurida are made. The species Stachorutes arlei is transferred once more from Furculanurida to Stachorutes.
-The objectives of this work were to evaluate the richness and diversity of the Poduromorpha fauna in two biotopes in Restinga de Maricá, RJ, Brazil, to identify the characteristic species of each biotope and to determine the relationships between the community structure and the abiotic environmental parameters. Representatives of the Poduromorpha (Collembola) order were studied under an ecological viewpoint in halophyte-psammophyte vegetation and foredune zone in preserved areas of Restinga de Maricá, a sand dune environment in the state of Rio de Janeiro, Brazil. The foredune zone showed the highest diversity, richness and equitability of springtail species. Differences in the fundamental, accessory and accidental species in each environment were encountered. Paraxenylla piloua was found to be an indicator species of the halophyte-psammophyte vegetation, while Friesea reducta, Pseudachorutes difficilis and Xenylla maritima were indicators of the foredune zone. The canonical correspondence analysis indicated pH, organic matter content and soil humidity as the most important factors influencing the spatiotemporal distribution of the species.Index terms: bioindicator, ecology, littoral, springtails. Estrutura de comunidades de Poduromorpha (Collembola) em áreas de restingaResumo -Os objetivos deste trabalho foram avaliar a riqueza e a diversidade da fauna de Poduromorpha em dois biótopos na Restinga de Maricá, RJ, identificar as espécies características de cada biótopo e determinar as relações da estrutura da comunidade com parâmetros ambientais abióticos. Representantes da ordem Poduromorpha (Collembola) foram estudados do ponto de vista ecológico nos ambientes de vegetação halófila-psamófila reptante e de primeiro cordão arenoso em áreas preservadas da Restinga de Maricá, localizada no Estado do Rio de Janeiro, Brasil. Os maiores valores de diversidade, riqueza e equitabilidade de espécies de colêmbolos foram observados no ambiente de primeiro cordão arenoso. Foram encontradas diferenças nas espécies fundamentais, acessórias e acidentais nos ambientes amostrados. Paraxenylla piloua atuou como indicadora de ambiente da vegetação halófila-psamófila reptante, ao passo que Friesea reducta, Pseudachorutes difficilis e Xenylla maritima mostraram-se indicadoras de ambiente de primeiro cordão arenoso. A análise de correspondência canônica mostrou que os fatores mais importantes na distribuição espaço-temporal das espécies foram pH, conteúdo de matéria orgânica e umidade do solo.Termos para indexação: bioindicador, ecologia, litoral, colêmbolos.
