The labrisomid genus Malacoctenus from Southwestern Atlantic is reviewed. Two new species of scaly blennies formerly reported by several authors as Malacoctenus triangulatus are described. One is found at the oceanic islands Fernando de Noronha Archipelago and Atol das Rocas, and the other is distributed along the Brazilian coastline. The two new species differ from other species of the genus and from each other by different combinations of the number of lateral-line scales, number and size of head cirri, and color pattern. Molecular data also support species' distinctiveness between M. triangulatus and the species described herein. Two additional recognized Brazilian species, M. delalandii and M. brunoi are described and illustrated and an identification key to all recognized Atlantic species is provided.
对来自西南大西洋的唇鳚属（Malacoctenus）进行了综述。描述了此前几位作者报道为三角唇鳚（Malacoctenus triangulatus）的两种新的栉齿鳚科鱼类。一种发现于海洋岛屿费尔南多·迪诺罗尼亚群岛和罗卡斯环礁，另一种分布于巴西海岸线。这两个新物种在侧线鳞数量、头部触须数量和大小以及体色模式的不同组合上与该属的其他物种以及彼此有所不同。分子数据也支持三角唇鳚与本文描述的物种之间的种间差异。描述并图示了另外两种已知的巴西物种，即德氏唇鳚（M. delalandii）和布鲁诺唇鳚（M. brunoi），并提供了所有已知大西洋物种的鉴别检索表。
