Schistobrachia jordaanae n. sp. (Copepoda: Siphonostomatoida: Lernaeopodidae) from gill filaments of a diamond ray (Gymnura natalensis) captured in the Indian Ocean and a key to species of Schistobrachia, Dendrapta, and Brianella

Schistobrachia jordaanae n. sp. (Copepoda: Siphonostomatoida: Lernaeopodidae) is described from adult female specimens collected from gill filaments of a diamond ray Gymnura natalensis (Gilchrist and Thompson, 1911) captured in the Indian Ocean off the South African coast. Schistobrachia jordaanae is best distinguished from its congeners by 2 unique characteristics: it possesses a necklike region between the origin of its maxillae and maxillipeds and the tips of its maxillae bifurcate repeatedly to form a rootlike anchor. © American Society of Parasitologists 2004.
