Smicridea (Rhyacophylax) Müller 1879 contains 106 species, 41 of which occur in Brazil, mainly in the Atlantic Forest biome. Despite its diversity, it is estimated that many undescribed species are believed to be housed in scientific collections, waiting to be described. Smicridea specimens housed in two Brazilian insect collections (Coleção Entomológica Professor José Alfredo Pinheiro Dutra, Rio de Janeiro and Museu de Zoologia da Universidade de São Paulo, São Paulo) were examined and two new species of S. (Rhyacophylax) were detected. The objective of this study is to describe and illustrate these species. Smicridea (Rhyacophylax) boraceia sp. nov. and Smicridea (Rhyacophylax) dumasi sp. nov. inhabit the Atlantic forest biome and can be recognized mainly by the morphology of tergum X and the phallic apparatus. Six species groups are recognized in S. (Rhyacophylax); however, the two new species described here cannot be placed in any of these groups.
斯米克里德摇蚊属（Rhyacophylax）由米勒于1879年建立，包含106个物种，其中41种分布于巴西，主要集中在大西洋森林生物群落。尽管该属物种丰富多样，但据估计仍有许多未被描述的物种保存在科学标本馆中有待鉴定。我们对保存在巴西两个昆虫标本馆（里约热内卢的若泽·阿尔弗雷多·皮涅罗·杜特拉昆虫标本馆和圣保罗的圣保罗大学动物博物馆）的斯米克里德摇蚊属标本进行了检查，并发现了两个新物种。本研究旨在对这些物种进行描述和阐释。新物种博拉塞亚斯米克里德摇蚊（Smicridea (Rhyacophylax) boraceia sp. nov.）和杜马斯斯米克里德摇蚊（Smicridea (Rhyacophylax) dumasi sp. nov.）栖息于大西洋森林生物群落，主要可通过第十腹节背板和阳茎的形态特征加以识别。在斯米克里德摇蚊属（Rhyacophylax）中可识别出六个物种组；然而，这里描述的两个新物种无法归入其中任何一组。
