Two new species of , n. sp. and n. sp., which were isolated from multiple species in North America and from in Japan, respectively, are described. The new species are each diagnosed by characters of the male tail and genitalia, in addition to molecular barcode differences that were previously reported. The description of n. sp. expands the suite of known nematode associates of , promoting ecological studies using a beetle that is an experimental model for insect-nematode-microbiota interactions in a semi-natural setting. Furthermore, our description of a third species, n. sp., sets up a comparative model for such ecological interactions, as well as other phenomena as previously described for , including maternal care through obligate vivipary, the evolution of reproductive mode, and extremophilic living.
描述了两个新物种，分别是从北美多种物种中分离出的 新种和从日本 中分离出的 新种。除了先前报道的分子条形码差异外，新物种还分别通过雄性尾部和生殖器特征进行诊断。 新种的描述扩展了已知的 线虫共生体种类，推动了利用一种甲虫进行的生态学研究，该甲虫是半自然环境中昆虫-线虫-微生物群相互作用的实验模型。此外，我们对第三个 物种 新种的描述建立了这种生态相互作用以及先前针对 所描述的其他现象的比较模型，包括通过专性胎生的母体护理、生殖模式的进化和极端嗜性生活。
