Physiculus sudanensis Paulin, 1989, a junior synonym of P. dalwigki Kaup, 1858 (Teleostei, Gadiformes, Moridae), with a redescription of P. dalwigki
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.
