A new genus and a new species of Paleonurini (Collembola, Neanurinae) are described in this paper. The new species Ectonura snowdeni sp. nov., is the first record of the austral genus Ectonura for the Neotropics. A new genus from Southeast Brazil, Itanura gen. nov., is created based mainly on head tubercles arrangement. Its type species is Neanura brasiliensis Arlé, 1959 comb. nov., which is redescribed with the designation of a lectotype. Its distribution range is expanded with two new records from high altitude mountains of Southeast Brazil. Specimens from these two localities exhibit small morphological differences with those of the type locality, which are discussed.
本文描述了古裸尾跳虫属（弹尾目，新裸尾跳虫亚科）的一个新属和一个新种。新物种斯诺登埃克托裸尾跳虫（Ectonura snowdeni sp. nov.）是南方的埃克托裸尾跳虫属在新热带地区的首次记录。基于头部瘤突排列，建立了一个来自巴西东南部的新属——伊塔努拉属（Itanura gen. nov.）。其模式种为巴西新裸尾跳虫（Neanura brasiliensis Arlé, 1959 comb. nov.），重新描述了该种并指定了选模标本。其分布范围因来自巴西东南部高海拔山区的两个新记录而扩大。来自这两个地点的标本与模式产地的标本在形态上存在细微差异，并对此进行了讨论。
