Description:A new species of deep-sea neolepadid stalked barnacle, Vulcanolepas verenae sp. nov., is described from Hafa Adai hydrothermal vent field in the Mariana back-arc basin, northwest Pacific. Vulcanolepas verenae sp. nov. is differentiated from other described species in the family morphologically by a mandible with a very small first tooth and small, non-protruding peduncular scales. Its gross external morphology exhibits a range of plasticity, similar to those previously reported from other neolepadid stalked barnacles. This is the first report of the genus Vulcanolepas in the northern hemisphere, and we discuss the phylogeography of Neolepadidae with a phylogenetic reconstruction based on the cytochrome c oxidase subunit I gene. We also discuss the relationship between key morphological characteristics and the feeding habits in the family, showing that, a number of Vulcanolepas species including Vulcanolepas verenae sp. nov. are specialized in culturing filamentous bacteria on their cirri.
