Eight species of Syphacia (Nematoda: Oxyuridae) have been reported from South America in rodents of the Sigmodontinae, only 1 of which has been recorded in Argentina. Syphacia (Syphacia) carlitosi n. sp. is described from the ceca of Akodon azarae bibianae and Akodon azarae hunteri (Sigmodontinae: Akodontini) captured in 3 provinces in the northeast region of Argentina. The new species is differentiated principally by the shape of the cephalic plate; distribution of submedian papillae and amphids; presence, extent, and shape of cervical alae in females; absence of lateral alae; absence of deirids; spicular and gubernaculum length; shape and structure of accessory hook of gubernaculum; and distance of mamelons, excretory pore, and vulva from the anterior extremity. This is the second record of Syphacia parasitizing rodents of the tribe Akodontini.
在南美洲已报道有8种管圆线虫属（线虫纲：尖尾科）寄生于稻鼠亚科啮齿动物，其中仅1种在阿根廷有记录。管圆线虫属（管圆线虫亚属）卡尔利托斯管圆线虫新种是从阿根廷东北地区3个省份捕获的阿扎拉稻鼠比比亚亚种和阿扎拉稻鼠亨特亚种（稻鼠亚科：稻鼠族）的盲肠中描述的。新物种主要通过以下特征区分：头板形状；亚中乳突和头感器的分布；雌性颈部翼膜的存在、范围和形状；无侧翼膜；无颈乳突；交合刺和引带长度；引带副钩的形状和结构；以及乳突、排泄孔和阴门距前端的距离。这是管圆线虫属寄生于稻鼠族啮齿动物的第二个记录。
