Abstract

In total, 17 specimens of Conger orbignianus Valenciennes, 1847 from waters off Mar del Plata, Argentina (38 degrees 08'S, 57 degrees 32'W) were examined for parasitic nematodes. A new nematode species, Cucullanus pedroi n. sp., is described (prevalence 76.5%, x intensity +/- SD = 3.8 +/- 2.7). The new species closely resembles some species parasitizing other anguilliform fishes; however, it can be distinguished from most of its congeners by the distribution pattern of caudal papillae (particularly fourth and eight pairs) and phasmids. Those congeners with similar pattern of papillae differ from the new species by the length of the spicules and gubernaculum and by the position of the excretory pore and deirids.

摘要

总共对17个于1847年采集自阿根廷马德普拉塔海域（南纬38°08′，西经57°32′）的康氏海鳗（Conger orbignianus Valenciennes）样本进行了寄生线虫检查。描述了一种新的线虫物种——佩德罗库氏线虫（Cucullanus pedroi n. sp.）（感染率76.5%，平均感染强度±标准差=3.8±2.7）。该新物种与寄生于其他鳗形目鱼类的一些物种非常相似；然而，它可通过尾乳突（特别是第四和第八对）和尾感器的分布模式与大多数同属物种区分开来。那些具有相似乳突模式的同属物种与新物种的区别在于交合刺和引带的长度以及排泄孔和侧器的位置。
