Abstract Neolepas osheai sp. nov. is described from
collections made at depths of 1200-1700 m within the Brothers Caldera, a
site of hydrothermal venting and active volcanism in the southern portion of
the Havre Trough.
N. osheai sp. nov. is similar to other
Neolepas
in that it is hermaphroditic, has very specialised cirri, and occupies a "deep
water" hydrothermal vent habitat. It differs from other species in its trophic
structures and the nature of the peduncle. This new record increases the number
of described
Neolepas species to four, three of which are living. The
other, a fossil, is however tentatively ascribed to the genus and is known in
rocks of Early Jurassic age. All are from the Southern Hemisphere.
