Abstract

Two nematode species isolated from sediments of the littoral zone of the South China Sea on the coast of Vietnam are described and illustrated. Microlaimus capitatus sp. n. is closely related to M. affinis Gerlach, 1958 and M. amphidius Kamran et al., 2009, but differs by having a thin, poorly developed pharyngostom, more posterior vulva and presence of terminal setae on the tail. The female of Dichromadora simplex Timm, 1961 is described and illustrated for the first time.

摘要

本文描述并图示了从越南海岸南海沿岸浅海区域沉积物中分离出的两种线虫。头状微线线虫新种（Microlaimus capitatus sp. n.）与1958年的亲缘微线线虫（M. affinis Gerlach）及2009年的双环微线线虫（M. amphidius Kamran et al.）密切相关，但不同之处在于其咽口薄且发育不良、阴门更靠后以及尾部有端毛。首次描述并图示了1961年的简单双色线虫（Dichromadora simplex Timm）的雌性。
