Two new species of trichuroid nematodes. Huffmanela japonica n. sp. and Huffmanela shikokuensis n. sp., are established on the basis of their egg morphology and biological characters; the eggs of both species occur in the musculature of marine fishes from the Inland Sea of Japan. The dark-shelled eggs of H. japonica are found locally in masses ("black spots") in the flesh of Upeneus bensasi (Temminck et Schlegel) (Mullidae, Perciformes) and are characterized mainly by their shape and size (58-69 x 26-30 microm), an aspinose superficial transparent envelope enclosing the egg proper, relatively small polar plugs, and by their thick egg wall (4-5 microm). The eggs of H. shikokuensis are also dark-colored and are found evenly distributed in the musculature of Stephanolepis cirrhifer (Temminck et Schlegel) (Monacanthidae, Tetraodontiformes); they are characterized mainly by their shape and size (78-90 X 36-45 microm), by a very thin and aspinose superficial transparent envelope, large polar plugs, and relatively thin egg wall (3 microm). Histological sections of the host's infected musculature showed the presence of H. shikokuensis nematodes inside the muscle cells and in the intercellular spaces. A key to Huffmanela species based on egg morphology is provided.
两种新的鞭尾线虫。基于卵的形态和生物学特征建立了日本赫夫曼线虫新种（Huffmanela japonica n. sp.）和四国赫夫曼线虫新种（Huffmanela shikokuensis n. sp.）；这两个物种的卵均存在于日本濑户内海海鱼的肌肉组织中。日本赫夫曼线虫的深色卵局部成团出现（“黑点”）于斑鳍红娘鱼（Upeneus bensasi (Temminck et Schlegel)，鲾科，鲈形目）的鱼肉中，其主要特征为形状和大小（58 - 69×26 - 30微米）、包裹卵体的无棘表面透明包膜、相对较小的极塞以及较厚的卵壁（4 - 5微米）。四国赫夫曼线虫的卵也是深色的，均匀分布于圆斑拟鳞鲀（Stephanolepis cirrhifer (Temminck et Schlegel)，单角鲀科，鲀形目）的肌肉组织中；其主要特征为形状和大小（78 - 90×36 - 45微米）极薄且无棘的表面透明包膜、大的极塞以及相对较薄的卵壁（3微米）。宿主受感染肌肉组织的组织学切片显示，肌肉细胞内和细胞间隙存在四国赫夫曼线虫。提供了基于卵形态的赫夫曼线虫属物种检索表。
