Hysterothylacium perezi n. sp. is described from the intestine of the "cuatete" Ariopsis guatemalensis Günther, 1864 (Osteichthyes: Ariidae), in Tres Palos, a coastal lagoon located in the Mexican Pacific basin. The new species differs from all other species of Hysterothylacium Ward and Magath, 1917, in possessing a spinous postcloacal pad. In addition, H. perezi is readily distinguished from the 21 species described in fishes from America and Hawaii by having the greatest number of caudal papillae (47 to 51 pairs + 1 single, precloacal papillae). This species is the third described from hosts inhabiting estuarine environments in America and the fourth reported in Mexico.
佩雷希氏子宫线虫新种（Hysterothylacium perezi n. sp.）是从1864年命名的危地马拉阿里奥鲇（Ariopsis guatemalensis Günther）（硬骨鱼纲：海鲶科）的肠道中发现的，该鱼采自位于墨西哥太平洋盆地的沿海泻湖三帕洛斯。这个新物种与1917年命名的子宫线虫属（Hysterothylacium）的所有其他物种不同，它具有一个带刺的泄殖腔后垫。此外，佩雷希氏子宫线虫很容易与从美洲和夏威夷鱼类中描述的21个物种区分开来，因为它具有最多数量的尾乳头（47至51对 + 1个单个的泄殖腔前乳头）。该物种是美洲河口环境宿主中描述的第三个物种，也是墨西哥报道的第四个物种。
