A new nematode species, Pseudocapillaria yucatanensis sp. n., is described from the intestine of the freshwater pimelodid catfish Rhamdia guatemalensis (Günther) from cenotes (= sinkholes) in Yucatan, Mexico. It differs from other three related species parasitizing freshwater fishes mainly in possessing the spicule with a simple rim of its proximal end and a non-expanded distal end, in the length of the spicule (0.218-0.295 mm), and the size (0.050-0.060 x 0.025-0.030 mm), shape and structure of eggs, and also in the host types and geographical distribution. Pseudocapillaria yucatanensis is the first known autochtonous species of Pseudocapillaria parasitizing freshwater fishes in Mexico.
一种新的线虫物种——尤卡坦假毛细线虫（Pseudocapillaria yucatanensis sp. n.），是从墨西哥尤卡坦半岛天然井（即沉洞）中的淡水油鲶科鱼类危地马拉河鲶（Rhamdia guatemalensis，冈瑟）的肠道中发现并描述的。它与寄生于淡水鱼类的其他三种相关物种的主要区别在于，其交合刺近端边缘简单，远端未膨大，交合刺长度为0.218 - 0.295毫米，卵的大小为0.050 - 0.060×0.025 - 0.030毫米，以及卵的形状和结构，同时还体现在宿主类型和地理分布上。尤卡坦假毛细线虫是墨西哥已知的首个寄生于淡水鱼类的本土假毛细线虫物种。
