Nematodes of the family Aspidoderidae (Nematoda: Heterakoidea) Skrjabin and Schikobalova, 1947, are widely distributed in the Americas. The family Aspidoderidae includes the subfamilies Aspidoderinae Skrjabin and Schikobalova, 1947, and Lauroiinae Skrjabin and Schikobalova, 1951. These two subfamilies are delineated by the presence or absence of cephalic cordons at the anterior region. The nematodes in the subfamily Aspidoderinae, which includes the genus AspidoderaRailliet and Henry, 1912, are represented by nematodes with anterior cephalic cordons at the anterior end. The nematodes of the genus AspidoderaRailliet and Henry, 1912, are found in the cecum and large intestine of mammals of the orders Edentata, Marsupialia and Rodentia. Species within this genus have many morphological similarities. The use of scanning electron microscopy allows the specific characterization of the species within this genus. In the present work, we describe a new species of Aspidodera parasite of the large intestine of Didelphis aurita (Mammalia: Didelphidae) Wied-Neuwied, 1826, collected from Cachoeiras de Macacu, Rio de Janeiro. The combination of light and scanning electron microscopy allowed us a detailed analysis of this nematode.
Aspidoderidae 科（线虫纲：异皮目）的线虫广泛分布于美洲。Aspidoderidae 科包括 Aspidoderinae 亚科和 Lauroiinae 亚科。这两个亚科的区别在于前区是否存在头索。Aspidoderinae 亚科的线虫，包括 Aspidodera Railliet 和 Henry，1912 属，其前端具有前头索。Aspidodera Railliet 和 Henry，1912 属的线虫存在于食虫目、有袋目和啮齿目哺乳动物的盲肠和大肠中。该属的物种具有许多形态相似之处。扫描电子显微镜的使用可以对该属内的物种进行具体的特征描述。在本工作中，我们描述了一种来自里约热内卢 Cachoeiras de Macacu 的 Didelphis aurita（哺乳纲：有袋目）大肠中的 Aspidodera 寄生虫新种。光镜和扫描电子显微镜的结合使我们能够对这种线虫进行详细的分析。
