Although little studied, infections with nematodes of the Onchocercidae Leiper, 1911, predominated by the genera Dipetalonema Diesing, 1861 and Mansonella Faust, 1929, are frequent in wild primates and human populations in the Neotropical forest areas. This study reports natural infections with Dipetalonema freitasi Bain, Diagne & Muller, 1987 and D. gracile (Rudolphi, 1809) in two free-living species of pitheciid primates, extending the known geographical distribution of these species to the forest of the Peruvian Amazon. Adult worms were recovered from the thoracic and abdominal cavities of two species of monkeys, Pithecia monachus monachus (É. Geoffroy Saint-Hilaire) and Cacajao calvus ucayalii (Thomas) (Primates: Pitheciidae), collected along the Yavari-Mirin River basin and analysed via light and scanning electron microscopy. Both host species represent new host records for D. freitasi and D. gracile. Morphometric data are also presented for the sampled filarial worms in addition to morphological details obtained through light and electron microscopy examination of D. freitasi specimens.
虽然研究较少，但1911年莱珀所描述的盘尾丝虫科线虫感染在新热带森林地区的野生灵长类动物和人类群体中很常见，其中以1861年迪辛所描述的双瓣线虫属和1929年福斯特所描述的曼森线虫属为主。本研究报告了在两种自由生活的伶猴科灵长类动物中发现的1987年贝恩、迪亚涅和米勒所描述的弗氏双瓣线虫以及（1809年鲁道夫所描述的）细双瓣线虫的自然感染情况，将这些物种已知的地理分布范围扩展到了秘鲁亚马逊森林。从沿着亚瓦里 - 米林河流域采集的两种猴子，即僧面猴（É. Geoffroy Saint - Hilaire）和乌卡亚利绒毛蛛猴（托马斯）（灵长目：伶猴科）的胸腔和腹腔中采集到了成虫，并通过光学显微镜和扫描电子显微镜进行了分析。这两种宿主物种均代表弗氏双瓣线虫和细双瓣线虫的新宿主记录。除了通过对弗氏双瓣线虫标本进行光学和电子显微镜检查获得的形态学细节外，还给出了所采样丝虫的形态测量数据。
