摘要

摘要：据报道，澳大利亚和新西兰出现了新的深海卷腹章鱼（章鱼目：卷腹章鱼）。有限的收藏品包括三个物种，一个是首次从澳大利亚水域报告的，另一个来自澳大利亚和新西兰，我们认为它们是新的科学物种。分类学的不稳定性和区域分类学的新颖性阻碍了任何物种明确归属于属。虽然我们认为没有任何物种是兄弟姐妹，甚至没有密切的亲缘关系，但每一个物种都属于Grimpoteuthis：G.greeni n.sp.，基于来自澳大利亚南部的三个标本；G.angularis n.sp.，基于来自新西兰的单个标本；以及第一个G.abyssicola O’Shea的雄性标本，1999年，以前在塔斯曼海中部发现，我们描述了它，并将其分布扩展到澳大利亚水域。这些分类群与其他暂时归属于灰蝶科的分类群之间的关系进行了评估，主要基于外壳的形态，其次是鳃的形态，我们提出将灰蝶初步分为三种形态。发布LSID:LSID:http://zoobank.org:pub:92ACA16A-CB40-4254-BF7A-EAB25977AA92

New records and two new species of Grimpoteuthis (Octopoda: Cirrata: Grimpoteuthididae) from southern Australia and New Zealand

ABSTRACT New deep-sea cirrate octopuses (Octopoda: Cirrata) are reported from around Australia and New Zealand. The limited collections comprise three species, one that is for the first time reported from Australian waters, and one from each of Australia and New Zealand that we deem to be new to science. Taxonomic instability and regional taxonomic novelty preclude the unambiguous attribution of any species to genus. While we consider no species to be sibling, or even closely related, each is attributed to Grimpoteuthis: G. greeni n. sp., based on three specimens from southern Australia; G. angularis n. sp., based on a single specimen from New Zealand; and the first male specimen of G. abyssicola O’Shea, 1999, formerly known from the central Tasman Sea, which we describe and extend the distribution of into Australian waters. Relationships between these taxa and others provisionally attributed to the Grimpoteuthididae O’Shea, 1999 are evaluated and based primarily on the morphology of the shell, and secondarily on that of the gill, we propose a preliminary division of Grimpoteuthis sensu lato into three sensu lato morphologies.

期刊介绍： Molluscan Research is an international journal for the publication of authoritative papers and review articles on all aspects of molluscan research, including biology, systematics, morphology, physiology, ecology, conservation, biogeography, genetics, molecular biology and palaeontology. While the scope of the journal is worldwide, there is emphasis on studies relating to Australasia and the Indo-west Pacific, including East and South East Asia. The journal’s scope includes revisionary papers, monographs, reviews, theoretical papers and briefer communications. Monographic studies of up to 73 printed pages may also be considered. The journal has been published since 1957 (as the Journal of the Malacological Society of Australia until 1993). It is free to members of the Malacological Society of Australasia and the Society for the Study of Molluscan Diversity.
