Keywords: Echiodon, Eurypleuron, pearlfish, New Zealand


A new species of pearlfish, Echiodon prionodon, is described from three specimens. This species is diagnosed by having a serrated margin on the posterior edge of the fangs, expanded thoracic plates on some abdominal vertebrae and ventral swimbladder tunic ridges. This species was only found in coastal waters around the North Island of New Zealand. The diagnosis of Eurypleuron is revised.
