The first morphological description of the male of Trypanoxyuris pigrae Solórzano-García, Nadler, and Pérez-Ponce de León, 2016 , is presented in this study. Morphological data are supported by molecular data. Specimens of T. pigrae were recovered after the necropsy of a roadkill black howler monkey (Alouatta pigra) in southeastern Mexico. Males of T. pigrae are characterized by having 3 notched lips and a long esophagus with a posterior bulb; they also show a single crested lateral alae, a single spicule, and 4 caudal papillae. Morphological features coincide with those of the previously described T. pigrae females, and molecular profiles confirmed species identification. Males of T. pigrae are very similar to those of Trypanoxyuris minutus, another species of pinworm that also parasitizes the black howler monkey, A. pigra; however, the shape of the lips represents a very reliable diagnostic feature. Because of this, detailed en face observations are recommended to discriminate between these pinworm species.
本研究首次对2016年索洛萨诺 - 加西亚、纳德勒和佩雷斯 - 庞塞·德莱昂描述的猪锥尾线虫雄虫进行了形态学描述。形态学数据得到了分子数据的支持。猪锥尾线虫标本是在对墨西哥东南部一只死于交通事故的黑吼猴（Alouatta pigra）进行尸检后获得的。猪锥尾线虫雄虫的特征是有3个有缺口的唇和一条带有后球的长食道；它们还具有单个有嵴的侧叶、单个交合刺和4个尾乳突。形态学特征与先前描述的猪锥尾线虫雌虫一致，分子图谱也证实了物种鉴定。猪锥尾线虫雄虫与微小锥尾线虫雄虫非常相似，微小锥尾线虫是另一种也寄生于黑吼猴（Alouatta pigra）的蛲虫；然而，唇的形状是一个非常可靠的诊断特征。因此，建议进行详细的正面观察以区分这些蛲虫物种。
