The order Isopoda Latreille, 1816 consists of species occurring in terrestrial, marine and freshwater environments. In the Southern Ocean (SO), this group is amongst the most speciose and occur at all depths. Isopoda biogeography, despite being studied since the first Antarctic expeditions, is still poorly known from a geographical point of view and shows large occurrence gaps for some groups in specific sectors of the SO. In this paper, we update the isopod checklists of the Ross Sea (RS) and of some peri-Antarctic areas, such as the South Orkney Islands (SOI) and the South Sandwich Islands (SSI), based on the study of museum vouchers curated by the Italian National Antarctic Museum (MNA, Section of Genoa).
A total of 279 MNA samples from 15 different expeditions were studied. From this material, consisting of 419 specimens, 41 accepted species distributed in 24 families and 51 genera were identified. Comparing this newly-obtained information with the GBIF (Global Biodiversity Information Facility) and OBIS (Ocean Biodiversity Information System) portal, 15 species are here reported for the first time in the Ross Sea, with five new records in the Ross Sea Marine Protected Area. All records are new for the Terra Nova Bay area, for which a checklist of this group has never been produced before.
等足目（Isopoda）于1816年由拉特雷尔（Latreille）建立，包含生活在陆地、海洋和淡水环境中的物种。在南大洋，该类群是物种最为丰富的类群之一，且分布于各个深度。尽管自首次南极探险以来就对等足目生物地理学展开了研究，但从地理学角度来看，其仍然鲜为人知，并且在南大洋某些特定区域，一些类群的分布存在很大空白。在本文中，我们基于对意大利国家南极博物馆（热那亚分馆，MNA）馆藏标本的研究，更新了罗斯海以及一些南极周边地区（如南奥克尼群岛和南桑威奇群岛）的等足目动物名录。
共研究了来自15次不同探险的279份MNA样本。从这些由419个标本组成的材料中，鉴定出了41个已接受的物种，它们分布在24个科和51个属中。将这些新获得的信息与全球生物多样性信息设施（GBIF）和海洋生物多样性信息系统（OBIS）门户网站进行比较，有15个物种首次在罗斯海被报道，其中5个是罗斯海海洋保护区的新记录。所有记录对于特拉诺瓦湾地区来说都是新的，此前该地区从未编制过该类群的名录。
