摘要
通过对从韩国两个不同地点的苔藓和落叶等陆生栖息地采集的双壳轮虫进行分类研究,发现了三个新种:Habrotrocha changhoi n. sp.、H. microcornis n. sp.和 Philodina undulata n. sp.。Habrotrocha microcornis n. sp.最重要的诊断特征是细小的距,距间非常宽,约为距基部宽度的 4-5 倍。Habrotrocha changhoi n. sp.和 H. microcornis n. sp.是来自韩国的第一个 Habrotrocha 新种。Philodina undulata n. sp.区别于其同属种的最显著特点是第一躯干假节在摄食时向前方扩展,以及丰满的躯干具有波浪状的侧缘,并在摄食时突然变细至臀部。本文对这三个新种进行了详细描述和图解。此外,本文还提供了这三个新种的线粒体细胞色素 c 氧化酶亚单位 I 基因(CO1)的部分序列。
Descriptions of three new species of Philodinida (Rotifera, Bdelloidea) from Korea
A taxonomic study on bdelloid rotifers collected from terrestrial habitats such as mosses and leaf litter at two different locations in Korea resulted in three new species, Habrotrocha changhoi n. sp., H. microcornis n. sp. and Philodina undulata n. sp. Habrotrocha changhoi n. sp. is easily distinguished from its congeners by five small dorsal humps on preanal pseudosegment. The most significant diagnostic characteristic of Habrotrocha microcornis n. sp. is the tiny spurs with very wide interspace, which is about 4–5 times as wide as spur base width. Habrotrocha changhoi n. sp. and H. microcornis n. sp. are the first new Habrotrocha species from Korea. The most prominent characteristics that distinguish Philodina undulata n. sp. from its congeners are the first trunk pseudosegment expanded anteriorly in feeding as well as the plump trunk that has wavy lateral margins and abruptly tapers to rump in feeding. Here these three new species are described in detail and illustrated. In addition, the partial sequences of mitochondrial cytochrome c oxidase subunit I gene (CO1) for these three new species are provided here.
期刊介绍:
Zootaxa is a peer-reviewed international journal for rapid publication of high quality papers on any aspect of systematic zoology, with a preference for large taxonomic works such as monographs and revisions. Zootaxa considers papers on all animal taxa, both living and fossil, and especially encourages descriptions of new taxa. All types of taxonomic papers are considered, including theories and methods of systematics and phylogeny, taxonomic monographs, revisions and reviews, catalogues/checklists, biographies and bibliographies, identification guides, analysis of characters, phylogenetic relationships and zoogeographical patterns of distribution, descriptions of taxa, and nomenclature. Open access publishing option is strongly encouraged for authors with research grants and other funds. For those without grants/funds, all accepted manuscripts will be published but access is secured for subscribers only.
