Pterygodermatites (Paucipectines) zygodontomis, a nematode parasite of the small intestine of the rodent Necromys lasiurus, from Uberlândia, Minas Gerais state, Brazil, was analysed by light and scanning electron microscopy. Additionally, phylogenies were inferred from the mitochondrially encoded cytochrome c oxidase I gene (MT-CO1). Details of the helminth surface, such as the oral aperture, cephalic papillae, papillae in the posterior region of the body and longitudinal cuticular elements represented by spine-like projections and fans are presented, adding new taxonomic details. Molecular phylogenetic analysis, based on the MT-CO1, demonstrated that P. (P.) zygodontomis and Pterygodermatites (Paucipectines) jaegerskioldi form a unique evolutionary unit in accordance with the subgenus Paucipectines and corroborated their occurrence in cricetid and didelphid hosts.
对来自巴西米纳斯吉拉斯州乌贝兰迪亚的锯齿米氏鼠（Necromys lasiurus）小肠内的线虫寄生虫——少栉翼皮螨（Pterygodermatites, Paucipectines）zygodontomis进行了光学显微镜和扫描电子显微镜分析。此外，还根据线粒体编码的细胞色素c氧化酶I基因（MT-CO1）推断了系统发育。文中展示了该蠕虫体表的细节，如口孔、头部乳突、身体后部的乳突以及由棘状突起和扇形物代表的纵向表皮成分，增添了新的分类学细节。基于MT-CO1的分子系统发育分析表明，zygodontomis少栉翼皮螨和耶氏少栉翼皮螨（Pterygodermatites, Paucipectines）jaegerskioldi根据少栉翼皮螨亚属形成了一个独特的进化单元，并证实它们存在于仓鼠科和负鼠科宿主中。
