Etymology: Gollum: Taken from a personnage of the J.R.R.Tolkien works "The Lord of the rings"; suluensis: Named in reference to the Sulu Sea, an important marine region of the southern Philippines with a rich biodiversity, which is also the type locality of this shark. The epithet suluensis established here has been used previously in combination with Gollum in biodiversity lists (i.e. Global Biodiversity Information Facility Data Portal and Global Names Index, GBIF, 2011), presumably based on holdings of the museums and collections web site for Philippine specimens. However, prior to its use herein, the name was not available (nomen nudum) as it failed to meet requirements of Article 13 of the code International Code of Zoological Nomenclature, 1999 (i.e. lacking a definition or description, as well as a designated type specimen)..
