A new species of the genus Hypleurochilus, endemic to Trindade Island and Martin Vaz Archipelago, off Brazil, is described. Hypleurochilus brasil sp. n. differs from its congeners in color pattern and anal-ray counts. A recent study shows a close relationship between H. brasil sp. n. and H. fissicornis. This new species is recorded from 3 to 15 m depth, solitary or in small groups (up to 10 individuals), always in small holes or associated with sea-urchins and sponges on the rocky reefs. Hypleurochilus brasil sp. n. is the eleventh recognized species of Hypleurochilus and the third species of this genus reported from the Brazilian Province.
描述了一种新的Hypleurochilus属物种，该物种为巴西近海的特林达迪岛和马丁瓦斯群岛所特有。巴西Hypleurochilus brasil sp. n.在颜色模式和臀鳍鳍条数上与其同属物种不同。最近的一项研究表明，巴西Hypleurochilus brasil sp. n.与裂角Hypleurochilus fissicornis关系密切。该新物种记录于3至15米深的海域，独居或成小群（最多10只个体），总是在小洞穴中，或与岩礁上的海胆和海绵共生。巴西Hypleurochilus brasil sp. n.是Hypleurochilus属中第十一个被认可的物种，也是该属中第三个在巴西海域被报道的物种。
