Abstract

A total of 8 specimens of Urophycis brasiliensis (Kaup, 1858) 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 bonaerensis n. sp., is described (prevalence 50%, mean intensity 15.5). The new species differs from its congeners in the distribution pattern of caudal papillae (particularly fourth pair) and phasmids, length of the body and spicules, and by the position of the excretory pore (in the posterior third of esophagus). Species of Cucullanus, reported previously as C. heterochrous Rudolphi, 1812, and Cucullanus sp. from U. brasiliensis from Puerto Quequén, Argentina (38 degrees 37'S, 58 degrees 53'W), are considered as members of the new species.

摘要

对采集自阿根廷马德普拉塔海域（南纬38°08′，西经57°32′）的8个巴西尾口鳗（Urophycis brasiliensis，考普，1858年）样本进行了寄生线虫检查。描述了一种新的线虫物种——博纳雷斯库拉线虫（Cucullanus bonaerensis）新种（感染率50%，平均感染强度15.5）。该新物种与其同属物种的区别在于尾乳突（特别是第四对）和尾感器的分布模式、身体和交合刺的长度，以及排泄孔的位置（在食管后三分之一处）。先前报道的来自阿根廷克肯港（南纬38°37′，西经58°53′）的巴西尾口鳗体内的鲁氏异尾库拉线虫（Cucullanus heterochrous Rudolphi，1812年）和库拉线虫属（Cucullanus sp.）物种被认为是该新物种的成员。
