摘要

Species of large, testate, rhizarian protists in the genus Gromia are often common in high-latitude coastal environments, including fjords, but are frequently overlooked and almost all are undescribed. Here, we describe three new gromiid species from the Nuuk fjord system on the west coast of southern Greenland. Morphologically, the new species differ in the size and shape of the test. Gromia cucumiformis sp. nov. is elongate, up to 5.5 mm long, with a length:width (L/W) ratio of 4.3-5.5; Gromia botelliformis sp. nov. is up to 2.1 mm long, with a L/W ratio of 3.0-4.8; Gromia brevis is typically less than 1.0 mm long, with a L/W ratio around 2.0. Genetically, they are well-characterised and split between two clades. Gromia cucumiformis and G. brevis branch with several species of deep-water gromiids from the Arabian Sea and the Weddell Sea, while G. botelliformis branches with deep Weddell Sea species and several unnamed and morphologically uncharacterised gromiids from different parts of the world. Gromia botelliformis and G. brevis are currently known only from the Nuuk fjords, but sequences of G. cucumiformis from Greenland group together with sequences from Svalbard and the White Sea. Our genetic data reveal four additional clades of undescribed Gromia species. One contains sequences from Greenland, Svalbard and the White Sea, two comprises sequence from Greenland and the White Sea and one is limited to sequences from Greenland. These results demonstrate the high genetic diversity of gromiids and their widespread distribution in Arctic as well as in deep-sea environments.

Botelliformis患有深婚前海洋物种和来自世界不同地区的几个未命名的和形态学上的不可思议的无论如何。 Gromia Botelliformis和G.Brevis目前只来自Nuuk峡湾，但从格兰兰集团的G.Cucumiformis序列与斯瓦尔巴特和白海一起。我们的遗传数据揭示了四种未描述的Gromia物种的额外片。一个包含格陵兰，斯瓦尔巴德和白海的序列，其中两个包括格陵兰和白海的序列，一个人仅限于格陵兰岛的序列。这些结果证明了Gromiids的高遗传多样性及其在北极以及深海环境中的广泛分布。
