A specimen of Holohalaelurus shark (Scyliorhinidae; Chondrichthyes) recently collected off southern Mozambique, represents a southward range extension of 2200km for the recently described, H. grennian Human 2006. This specimen presents not only a significant extension of its known distribution, but is also only the second female specimen known for this species. Moreover, the specimen exhibits morphological characters, particularly colouration, which are more typically attributed to congeners occurring in the southern part of its range. This paper is an account of the range extension for H. grennian, and compares the morphological and colouration differences in this specimen compared to the original species description. A shape analysis is conducted on the specimen, and a revised zoogeography of the genus Holohalaelurus is presented.
