Validity of Physiculus sudanensis was questioned based on the similarities with Physiculus dalwigki and the erroneously assigned type location of ‘Côtes du Soudan’ in the Indian Ocean. After a careful comparison with the holotype of P. dalwigki, P. sudanensis is herein considered as a junior synonym of P. dalwigki. A redescription of P. dalwigki is also presented. The genus Physiculus now contains 41 species worldwide, 10 of which occur in the Indian Ocean.
