IntroductionThe Aotearoa New Zealand ghost shrimp of the infraorders Axiidea and Gebiidea have never been comprehensively reviewed, with recent work uncovering a diverse regional fauna representing eight of the 14 known families.MethodsUsing standard morphological and DNA sequencing tools, the family Callianopsidae is, for the first time, recorded off New Zealand, represented by a new species of Vulcanocalliax.ResultsThe new species was found near hydrocarbon seeps on the Hikurangi Margin, on the eastern New Zealand continental slope, and is only the second species now known in this genus. The single congener, V. arutyunovi, is only known from a mud volcano in the Gulf of Cádiz, off the Iberian Peninsula. Vulcanocalliax sp. nov. was formerly reported as an unnamed host of a new endemic New Zealand rhizocephalan barnacle Parthenopea australis and is here formally described as Vulcanocalliax beervana sp. nov.DiscussionThe new species differs, e.g., in the shape of the anterior carapace margin (convexly rounded and without elevated postantennal shoulder present in V. arutyunovi), the ocular peduncle having a convex anterolateral margin (compared to a straight margin), and the uropodal exopod has a dorsomedian ridge, lacking the elevated anterior portion that is distinct in V. arutyunovi. This brings the number of described New Zealand ghost shrimp species to 18. A key to all known Callianopsidae is provided.ZOOBANKLSID urn:lsid:zoobank.org:pub:4EDE6CE1-B644-4FFB-94CA-C8725A7549DD.

新西兰 Aotearoa 附近 Hikurangi 边缘首次记录 Callianopsidae 科（十足目：Axiidea）和 Vulcanocalliax 新种，并附有 Callianopsidae 物种检索表


介绍新西兰幽灵虾下目 Axiidea 和 Gebiidea 从未被全面审查过，最近的工作揭示了代表 14 个已知科中的 8 个科的多样化区域动物群。方法使用标准形态学和 DNA 测序工具，首次对 Callianopsidae 科进行了研究。结果该新物种是在新西兰东部大陆坡 Hikurangi 边缘的碳氢化合物渗漏附近发现的，是该属中目前已知的第二个物种。单一同系物 V. arutyunovi 仅在伊比利亚半岛附近加的斯湾的一座泥火山中被发现。 Vulcanocalliax sp。十一月此前曾被报道为一种新的新西兰特有根头藻藤壶 Parthenopea australis 的未命名宿主，此处正式描述为 Vulcanocalliax beervana sp.。 nov.讨论新物种的不同之处在于，例如，前甲边缘的形状（V. arutyunovi 中呈凸圆形且没有升高的触后肩部）、具有凸前外侧边缘的眼脚（与直边缘相比）以及尾足外足类有一个背脊，缺乏 V. arutyunovi 所特有的升高的前部。这使得描述的新西兰幽灵虾物种数量达到 18 个。提供了所有已知 Callianopsidae 的密钥。ZOOBANKLSID urn:lsid:zoobank.org:pub:4EDE6CE1-B644-4FFB-94CA-C8725A7549DD。
