Cosmocercoidea总科包括三个科：Cosmocericidae，Kathlaniidae和Atomtidae。关于Cosmocercoidea的核苷酸序列的信息非常有限，整个超科的分子分类进展缓慢。草履虫属（Grassenema）是一种寄生于蹄兔消化道的线虫，包括三种：Procaviae草履虫（Grassenema procaviae）、G.c. dendrohyraci和G.蹄兔该属的模式种为G. Procaviae分离自海兔角（Cape hyraxes）（Procavia capensis）的消化道，具有引起胃溃疡的潜力。虽然G. procaviae是一种常见的寄生虫角蹄兔，没有遗传信息的寄生虫是目前。本研究首次获得了G.并进行了详细的形态学观察。此外，进行分子系统发育分析，并使用18S和28S rDNA序列的寄生虫的分类位置进行了评估。这些数据将有助于G. Procaviae和未来的系统发育分析在蝗科。
The superfamily Cosmocercoidea comprises three families: Cosmocericidae, Kathlaniidae and Atractidae. Information on the nucleotide sequences of the Cosmocercoidea is quite limited, and the molecular classification of the whole superfamily has been slow to progress. The genusGrassenemaof the family Atractidae is a parasitic nematode group that occurs in the digestive tract of hyraxes and includes three species:Grassenema procaviae,G. dendrohyraci,andG. hyracis. The type species of the genus,G. procaviae, was isolated from the digestive tract of Cape hyraxes (Procavia capensis) and has the potential to cause gastric ulcers. AlthoughG. procaviaeis a common parasite of Cape hyraxes, no genetic information for the parasite is currently available. In this study, we obtained the first genomic sequences ofG. procaviaeand performed detailed morphological observations. Furthermore, molecular phylogenetic analysis was performed, and the taxonomic position of the parasite was evaluated using 18S and 28S rDNA sequences. Those data will be useful for molecular identification ofG. procaviaeand future phylogenetic analysis within the Atractidae.
