Huffmanela moraveci n. sp. (Nematode: Trichosomoididae) is described from the skin of fins and gills of the silversides Odontesthes smitti Lahille, 1949, and Odontesthes nigricans Richardson, 1848 (Pisces: Atheriniformes), from southwestern Atlantic coast, on the basis of the morphology of adults and eggs found in the host tissues. Huffmanela moraveci n. sp. can be distinguished from Huffmanela carcharini, H. banningi, H. japonica, H. mexicana, H. paronai, H. schouteni, H. shikokuensis, H. branchialis, H. filamentosa, H. ossicola, and H. lata by the size and shape of the eggs. The adult stage of H. moraveci n. sp. can be differentiated from H. hufmani and H. canadensis by the position of the nerve ring and by the total esophagus length/body length ratio. Huffmanela moraveci n. sp. also differs from H. huffmani by the presence of bacillary bands and by the body length. This is the first report of a species of Huffmanela in South America, the first report of a species of Huffmanela with Odontesthes spp. as host, and the third known adult form in the genus.
莫拉韦奇赫夫曼线虫新种（线虫纲：毛圆线虫科）是根据在宿主组织中发现的成虫和虫卵形态，从西南大西洋沿岸的银汉鱼科鱼类斯氏银汉鱼（1949年拉希尔命名）和黑鳍银汉鱼（1848年理查森命名）（硬骨鱼纲：银汉鱼目）的鳍和鳃皮肤中描述的。莫拉韦奇赫夫曼线虫新种可根据虫卵的大小和形状与卡氏赫夫曼线虫、班氏赫夫曼线虫、日本赫夫曼线虫、墨西哥赫夫曼线虫、帕罗内赫夫曼线虫、舒滕赫夫曼线虫、四国赫夫曼线虫、鳃赫夫曼线虫、丝状赫夫曼线虫、骨赫夫曼线虫和宽赫夫曼线虫区分开来。莫拉韦奇赫夫曼线虫新种的成虫阶段可根据神经环的位置以及食管总长度与体长的比例与赫夫曼赫夫曼线虫和加拿大赫夫曼线虫区分开来。莫拉韦奇赫夫曼线虫新种还因存在杆菌带和体长与赫夫曼赫夫曼线虫不同。这是南美洲首次报道赫夫曼线虫属的一个物种，也是首次报道以银汉鱼属鱼类为宿主的赫夫曼线虫属物种，以及该属已知的第三种成虫形态。
