Description of a New Subspecies Zanclorhynchus spinifer heracleus subsp. nov. from the Ridge of Hercules (Pacific–Antarctic Ridge)


New subspecies of Zanclorhynchus spinifer heracleus subsp. nov. from the Ridge of Hercules (Pacific–Antarctic Ridge) is described. The type series of the new subspecies was caught on both large banks of the ridge (Central Bank and the South Bank) at the depths of 170–380 m. The new subspecies differs from the nominative subspecies in the degree of development of the arming, particularly, by the cranial spines and of the dorsal fin. The key to the Zanclorhynchus species and subspecies is developed and presented.
