Eukaryotic microbial diversity is known to be extensive but remains largely undescribed and uncharted. While much of this unknown diversity is composed of inconspicuous flagellates and parasites, larger and morphologically distinct protists are regularly discovered, most notably from poorly studied regions. Here we report a new flagship species of hyalospheniid (Amoebozoa; Arcellinida; Hyalospheniformes) testate amoeba from New Zealand and an unusual story of overlooked description under a preoccupied name and subsequent oversight for nearly one century. Through a process involving The Māori Language Commission, we named the species Apodera angatakere, meaning “a shell with a keel.” This species resembles Apodera vas but differs by the presence of a distinctive hollow keel. Cytochrome Oxidase Subunit 1 (COI) sequence data show that this species forms a distinct clade nested within genus Apodera. This conspicuous species is so far known only from New Zealand and is restricted to peatlands. It is one of the few examples of endemic microorganisms from this biodiversity hotspot and biogeographer's paradise. As over 90% of New Zealand's peatlands have been lost since European colonization and much of the remaining surfaces are threatened, Apodera angatakere could be a flagship species not only for microbial biogeography but also for island biodiversity conservation.

表面描述和忽视了 92 年，重新发现和修正：Apodera angatakere（Amoebozoa：Arcellinida：Hyalospheniformes）是来自新西兰 Aotearoa 的新旗舰有遗嘱变形虫分类单元


众所周知，真核微生物的多样性非常广泛，但在很大程度上仍未被描述和未知。虽然这种未知的多样性大部分由不显眼的鞭毛虫和寄生虫组成，但经常发现更大且形态独特的原生生物，尤其是来自研究不足的地区。在这里，我们报道了来自新西兰的一种新的透明蜥蜴旗舰物种（Amoebozoa；Arcellinida；Hyalospheniformes）有遗嘱阿米巴虫，以及一个在一个全神贯注的名称下被忽视的描述和随后近一个世纪的监督的不寻常故事。通过毛利语言委员会的参与，我们将这个物种命名为Apodera angatakere ，意思是“带龙骨的贝壳”。该物种与Apodera vas相似，但不同之处在于具有独特的中空龙骨。细胞色素氧化酶亚基 1 (COI) 序列数据表明，该物种形成了一个嵌套在Apodera属内的独特进化枝。迄今为止，这种引人注目的物种仅来自新西兰，并且仅限于泥炭地。它是来自这个生物多样性热点和生物地理学家天堂的特有微生物的少数例子之一。自欧洲殖民以来，新西兰超过 90% 的泥炭地已经消失，并且大部分剩余地表都受到威胁， Apodera angatakere不仅可以成为微生物生物地理学的旗舰物种，而且可以成为岛屿生物多样性保护的旗舰物种。
