A new species of the genus Neoverruca(Cirripedia, Thoracica, Verrucidea, Neoverrucidae) from a hydrothermal vent area in the Okinawa Trough

A new species of the neoverrucid barnacle genus NeoverrucaNewman, 1989, N. intermediasp. nov., collected from a hydrothermal vent area in the Okinawa Trough, is described and illustrated. It differs from N. brachylepadoformisNewman, 1989 by the apical end of the inner surface of the movable scutum being in a pocket-form, with a longitudinal groove upwards, and without median ridges; the adductor ridge (or myophore) of the fixed scutum stout and the inner distal part of the scutum without longitudinal ridge.
