生殖器隐杆线虫是该属特有的一种。它寄生在松墨天牛的卵巢或睾丸中，在其生活史中有一个类似新硬线虫的可培养食菌期，而该属的其他物种寄生于树皮甲虫并具有典型的不可培养的尿囊线虫生活史。由于该种的描述仅基于形态，因此有必要确认该种的系统发育和分类地位。生殖器拉伤。基于核糖体RNA序列的分子系统发育分析表明，C.生殖器与Contortylenchusspp形成一个支撑性良好的分支。从树皮甲虫中分离到的一种来自伊朗的不明松毛虫，以及从美国的金属钻木虫Agilus macerLeConte(鞘翅目：臭虫科)中分离出来的‘DelAdenuscf.laricis’。FC的通用状态。系统发育分析支持该属的系统发育，该属的多样性可能高于目前的预期。
Contortylenchus genitalicolais a unique species within the genus. It parasitises the ovary or testis of the longhorn beetle,Monochamus alternatus, and has a neotylenchid-like culturable mycetophagous phase within its life cycle, while the other species in the genus parasitise bark beetles and have a typical unculturable allantonematid life cycle. Because the species was described based solely on morphology, it was necessary to confirm the phylogenetic and taxonomic status ofC. genitalicola. A molecular phylogenetic analysis of the species based on ribosomal RNA sequences revealed thatC. genitalicolaforms a well-supported clade withContortylenchusspp. isolated from bark beetles, an unidentified allantonematid from Iran, and ‘Deladenuscf.laricis’ isolated from the metallic wood-boring beetle,Agrilus macerLeConte (Coleoptera: Buprestidae), in the USA. The generic status ofC. genitalicolawas supported by phylogenetic analysis, and the analysis also suggests that the diversity of the genus could be higher than currently expected.
