Furthermore, we include all additional records Brazilian Collembola during 2010 2011 as update species list. The was made same methodology criteria Culik Zeppelini (2003), (2010). All data will fit table marked differently to be recognized at glance. references presented here are restricted citations concerning only; therefore not repeated.

We presented a synthesis of Brazilian Entomobryomorpha species and new records the oceanic islands located in Equatorial Atlantic. In this work, we observed global distributions that inhabit islands. distribution maps for all found on closest continent. Our study showed occur also American continent, mainly neotropical region, or are widespread. established neotype first Collembola described Brazil together with detailed morphological study.

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