摘要

根据分子标记、交配实验、形态观察和生态学数据，描述了两个新的Pristionchus物种（线虫纲：Diplogastridae）。这两个种都是从韩国不同的疤腹甲虫中采集的，具有性腺生殖模式，属于太平洋支系的一个亚支系。在实验室条件下，Pristionchus coreanus n. sp.并不表现出雌雄同体的形态，因此可能适合研究多态性的获得和丧失。Pristionchus hangukensis n. sp.在系统发育上与中国和日本的物种接近，有助于将亚洲支系与美洲支系分开。

Description of two new Pristionchus species from South Korea.

Based on molecular markers, mating experiments, morphological observations and ecological data, two Pristionchus species (Nematoda: Diplogastridae) new to science are described. Both were collected from different Scarabaeoid beetles in South Korea, have a gonochoristic mode of reproduction and fall into a sub-clade of the pacificus clade. Pristionchus coreanus n. sp. does not show a eurystomatous morph under laboratory conditions and might therefore be suitable for the study of gain and loss of polymorphism. Pristionchus hangukensis n. sp. is phylogenetically close to Chinese and Japanese species and helps to separate an Asian clade from an American clade.
