Rhabdochona (Rhabdochona) acuminata is redescribed from specimens parasitizing Diplomystes mesembrinus (Siluriformes: Diplomystidae) and Percichthys trucha (Perciformes: Percichthyidae) from the Chubut River, Patagonia, Argentina. The present report is the first record of this nematode in D. mesembrinus; it also confirms P. trucha as host and Patagonia as a region of distribution for R. (R.) acuminata. Morphological features of the species were described using light and scanning electron microscopy. When compared with previous descriptions from Brazil, very similar morphology is observed. But large morphometric variability is found, mainly in body size, spicule ratio, and number and arrangement of pre- and postcloacal papillae.
从阿根廷巴塔哥尼亚丘布特河寄生在半滑南美鲶（鲇形目：南美鲶科）和特鲁查鲈（鲈形目：鲈科）体内的标本中，对尖吻似袋线虫进行了重新描述。本报告是该线虫在半滑南美鲶体内的首次记录；它还证实了特鲁查鲈是其宿主，以及巴塔哥尼亚是尖吻似袋线虫的一个分布区域。使用光学显微镜和扫描电子显微镜描述了该物种的形态特征。与之前来自巴西的描述相比，观察到形态非常相似。但发现了很大的形态测量变异性，主要体现在体长、交合刺比例以及泄殖腔前后乳突的数量和排列上。
