Summary:A new species of the genus Sorsogona is described here from four specimens taken off the coasts of Mozambique and Somalia. It differs primarily from the closely related S. prionota (Sauvage, 1873) and S. nigripinna (Regan, 1905) in colour pattern and number of horizontal scale rows above the lateral line (4-6 in S. prionata, 8 in S. humerosa, and 9-10 in S. nigripinna). Colour pattern differences in the caudal fin include: 3-5 dark bars in S. prionata, 2 broader bars in S. humerosa, and a uniform dusky pattern in S. nigripinna. A key to the species of Sorsogona from the Western Indian Ocean (WIO) is also included.
