We give descriptions of five new enchytraeid species (Enchytraeidae, Oligochaeta) from Korea: Henlea magnaampullacea sp. n., Fridericia sphaerica sp. n., F. cusanicaformis sp. n., F. granulocyta sp. n. and Mesenchytraeus calyx sp. n., with morphological and molecular (mitochondrial cytochrome c oxidase subunit I, nuclear histone 3 genes and nuclear ribosomal ITS region sequences) data. In total, 19 enchytraeid species belonging to seven genera have been found in the studied woodland and agronomical soil samples. Apart from the five new species, three further species are new for the Korean enchytraeid fauna, Enchytraeus christenseni, E. dichaetus, and Achaeta cf. brevivasa. Molecular taxonomical analyses show that the Korean species resembling H. ventriculosa is not identical with the European species, furthermore sequence analysis of individuals morphologically identified as F. seoraksani indicate the possibility of species-complexity and the presence of cryptic species.
我们描述了来自韩国的五种新的线蚓科物种（线蚓科，寡毛纲）：大壶腹亨氏线蚓（Henlea magnaampullacea sp. n.）、球形弗里德里西亚线蚓（Fridericia sphaerica sp. n.）、库萨尼形弗里德里西亚线蚓（F. cusanicaformis sp. n.）、粒状细胞弗里德里西亚线蚓（F. granulocyta sp. n.）和花萼间线蚓（Mesenchytraeus calyx sp. n.），并提供了形态学和分子学（线粒体细胞色素c氧化酶亚基I、核组蛋白3基因和核核糖体ITS区域序列）数据。在所研究的林地和农田土壤样本中，总共发现了属于七个属的19种线蚓科物种。除了这五个新物种外，另外三个物种对韩国线蚓动物区系来说也是新物种，即克里斯滕森线蚓（Enchytraeus christenseni）、双歧线蚓（E. dichaetus）和短刚毛似刺线蚓（Achaeta cf. brevivasa）。分子分类分析表明，与腹侧亨氏线蚓相似的韩国物种与欧洲物种并不相同，此外，对形态上鉴定为雪岳山弗里德里西亚线蚓（F. seoraksani）的个体进行的序列分析表明，可能存在物种复合体和隐存种。
