A review of the Oxyurids parasites of Primates shows that most of the species described in the Malagasy Lemurs and in the Old World Monkeys are not single species, but couples of sister-species. The sister-species of each couple may be differentiated sometimes only by the characteristics of male spicule (less evoluated species), sometimes by other characteristics (cephalic structures, length of oesophagus, etc., in more evoluated species). In the first instance only males can be identified, in the second instance females may also be identified. In the Human parasites, which are very closely related to those of the Old World Monkeys, two types of spicules were described and we consider that each type belongs to a different species: Enterobius vermicularis (L., 1758) for the larger spicule (100 to 122 micrometers), and Enterobius gregorii n. sp. for the shorter spicule (70 to 80 micrometers).
对灵长类动物尖尾线虫寄生虫的综述表明，在马达加斯加狐猴和旧世界猴中描述的大多数物种并非单一物种，而是姐妹物种对。每对姐妹物种有时可能仅通过雄刺特征（进化程度较低的物种）来区分，有时则通过其他特征（头部结构、食管长度等，进化程度较高的物种）来区分。在第一种情况下，只能识别雄性；在第二种情况下，雌性也可能被识别。在与旧世界猴的寄生虫密切相关的人类寄生虫中，描述了两种类型的刺，我们认为每种类型属于不同的物种：较大刺（100至122微米）的蠕形住肠线虫（L.，1758），以及较短刺（70至80微米）的新物种格雷戈里住肠线虫。
