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.

一种新的深海新鳞茎茎藤壶，Vulcanolepas verenae sp。十一月 根据西北太平洋马里亚纳弧后盆地的哈法阿代热液喷口领域进行了描述。Vulcanolepas verenae sp。十一月 下颌骨在形态上与下颌骨中其他描述物种有所区别，下颌骨具有非常小的第一齿和小的，不突出的人为鳞状鳞片。它的总体外部形态表现出一定的可塑性，类似于先前从其他新鳞茎茎藤壶中报告的可塑性。这是北半球Vulcanolepas属的首次报道，我们讨论了新鳞科的系统学，并基于细胞色素c进行了系统发育重建。氧化酶亚基I基因。我们还讨论了在家庭中主要的形态特征和食性的关系，可见，一些Vulcanolepas物种，包括Vulcanolepas verenae SP。十一月 专长于在其卷毛上培养丝状细菌。
