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.

Aimed at extending the incipient knowledge of Dicranocentrus in Brazil, in this study we describe and illustrate the morphology and chaetotaxy of four new species from Espírito Santo, Minas Gerais and São Paulo States and also two new records of D. heloisae for Minas Gerais and São Paulo States. The new species D. magnus sp.n., D. albicephalus sp.n. and D. marimutti sp.n. belong to the gracilis-group and D. pikachu sp.n. to the marias-group. A map with their distribution in Brazil and a table with Neotropical species’ main characteristics are also provided. The species herein reported represent the first record of Dicranocentrus for São Paulo State.

The fauna of south‐east Brazilian mountains was sampled and revealed two new species of Frieseinae, Friesea curupira sp. nov. and Friesea boitata sp. nov. The first is an unpigmented species with 1 + 1 eye, no furca and two anal spines. The second species is very similar to F. reducta Denis, 1931. Comments are made about a complex of species that also share many similarities within the ‘reducta group’. Remarks are made on tegumentar protuberances of subcoxae 1 of legs of Frieseinae.
