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

摘要

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.
