Corcyrogobius pulcher sp. nov. is described from off Île de Ngor, Dakar, Senegal. Corcyrogobius pulcher is distinguished from its two congeners by having the rear edge of the jaws ending posteriorly below mideye, second dorsal fin I/9, pectoral fin rays 17, pelvic fins oval or truncated posteriorly, scales in lateral series 26-27, anterior oculoscapular head canal with pore β, suborbital row b of sensory papillae anteriorly beginning below vertical of posterior edge of eye, dark vertical caudal bar, branchiostegal membrane without intense dark spot, cheek with two oblique whitish stripes, the first going from the eye downwards and forward to the posterior jaws, the second on the preopercular, alternating with brown oblique stripe going from behind the eye downwards and forward across the cheek. Furthermore, mitochondrial COI-barcoding data unambiguously support the species-level distinctiveness of the three Corcyrogobius species. A key to the species of Corcyrogobius is provided.
美丽科西鳚（Corcyrogobius pulcher）新物种是在塞内加尔达喀尔的恩戈尔岛附近被发现并描述的。美丽科西鳚与它的两个同属物种的区别在于：其颌骨后缘在眼中点下方结束；第二背鳍有1根硬棘和9根软鳍条；胸鳍有17根鳍条；腹鳍呈椭圆形或后缘截形；侧线鳞有26至27枚；前眶肩胛头部管道有β孔；感觉乳突的眶下排b列在眼后缘垂线下方开始；尾鳍有深色垂直条纹；鳃盖膜无深色密集斑点；脸颊有两条斜向白色条纹，第一条从眼睛向下向前延伸至后颌，第二条在鳃盖前骨上，与从眼后向下向前穿过脸颊的棕色斜条纹交替。此外，线粒体细胞色素氧化酶亚基I（COI）条形码数据明确支持了这三种科西鳚在物种水平上的独特性。文中还提供了科西鳚属物种的检索表。
