The enchytraeid fauna of three areas in Jeju Island (Korea) was studied, and comparative morphological and molecular taxonomic examinations (based on CO1, ITS and H3 sequences) were performed on nine samples collected in 2016. Twenty-two enchytraeid species were recorded and identified. The descriptions of two new species ( and ) are presented in this paper. The main diagnostic features of are: three pairs of pyriform glands per segment, clitellum with two "baguette-like" packages of glands, dorsal blood vessel from VII, secondary pharyngeal glands absent, oesophageal appendages well developed, two pairs of preclitellar nephridia, the reproductive organs (except the spermathecae in V) shifted one segment forward. The main features of are that they are large worms, have up to 2-4 chaetae in bundles, strong body wall, thick cuticle, five pairs of preclitellar nephridia, c-type coelomo-mucocytes sometimes with some refractile vesicles, chylus cells in XII-XV, sperm funnels approximately twice as long than wide, spermathecae with long ectal duct without glands, ampullae surrounded distally by about 9-12 sessile diverticula of varying size. Molecular phylogenetic analyses supported the morphological results and confirmed the status of the two new species.
对韩国济州岛三个地区的线蚓动物区系进行了研究，并对2016年采集的9个样本进行了比较形态学和分子分类学检查（基于CO1、ITS和H3序列）。记录并鉴定了22种线蚓。本文给出了两个新物种（ 和 ）的描述。 的主要诊断特征为：每节有三对梨形腺，具环带，有两个“法式长棍面包状”腺包，背血管从第七节开始，无次生咽腺，食管附属物发达，有两对环带前肾管，生殖器官（除第五节的受精囊外）向前移一节。 的主要特征是体型较大，每束最多有2 - 4根刚毛，体壁强壮，角质层厚，有五对环带前肾管，c型体腔粘液细胞有时有一些折射小泡，第十二至十五节有乳糜细胞，精子漏斗长约为宽的两倍，受精囊有长的外管且无腺体，壶腹远端被约9 - 12个大小不一的无柄憩室包围。分子系统发育分析支持了形态学结果，并确认了这两个新物种的地位。
