In the Neotropical Region, Phlugidini is the most diverse tribe of Meconematinae, with 62 valid species in 10 genera, six of them recorded from Brazil. Brachyphlugis gen. nov. is described herein based on two new species, Brachyphlugis longicercalis sp. nov. (type species) and Brachyphlugis curvata sp. nov., collected in Parque Nacional do Itatiaia and Reserva Biológica do Tinguá, both in the Atlantic Forest of Rio de Janeiro State. The new genus is most similar to Neophlugis, but it can be distinguished from the latter and other neotropical Phlugidini by the following combination of characteristics: (1) mandibles symmetrical; (2) tegmen extending beyond metanotum; (3) pronotal disk posterior margin convex; (4) tenth tergite strongly projected and downcurved; (5) male cercus pronounced with a larger base and acuminate apex; (6) paraproct modified with developed spine; (7) male subgenital plate with two distolateral projections connected to a pair of styles; and (8) female subgenital plate wider than long, posterior margin with two projections. An up-to-date key to neotropical Phlugidini genera is also provided.
在新热带区，Phlugidini 是 Meconematinae 中最多样化的部落，有 62 个有效种，分布于 10 个属中，其中 6 个种记录于巴西。本文基于两个新种描述了 Brachyphlugis 属，即 Brachyphlugis longicercalis sp. nov.（模式种）和 Brachyphlugis curvata sp. nov.，这两个新种均采自里约热内卢州大西洋森林的伊塔蒂亚伊国家公园和廷瓜保护区。新属与 Neophlugis 最为相似，但可通过以下特征组合与后者和其他新热带 Phlugidini 相区别：（1）下颚对称；（2）前翅超过中胸；（3）前胸盘后缘凸；（4）第十背板强烈突出并向下弯曲；（5）雄虫尾须明显，基部较大，尖端渐细；（6）尾突具发达的刺；（7）雄生殖下板具两个远端突出，连接一对尾须；（8）雌生殖下板宽于长，后缘有两个突出。本文还提供了最新的新热带 Phlugidini 属的检索表。
