INTRODUCTION Although many batoid species, known as final hosts of lecanicephalidean cestodes, exist in the Persian Gulf, no knowledge regarding this cestode order is available for this region. This study is the first one focusing on this order in the Persian Gulf. METHODS A total of 11 cowtail stingrays, Pastinachus sephen (Forsskål), were collected from the north eastern Persian Gulf. Isolated cestodes were fixed in 10% seawater-buffered formalin and stored in 70% ethanol. For morphological examinations, worms were stained using acetic carmine; a subset was prepared for SEM. RESULTS A new species of Polypocephalus Braun, 1878 was described. Polypocephalus barsami sp. nov. is the only species within its genus reported outside the waters of Japan, India, Sri Lanka, and Egypt in the Indian Ocean. Since the microtriches were not described in the generic diagnosis of Polypocephalus, the description of the microtriches is added based on the standardised terminology. Furthermore, the characteristics of this new species were discussed and compared within Polypocephalus, many species of which have poor descriptions. CONCLUSIONS Polypocephalus barsami sp. nov. is the first report of the genus Polypocephalus in the Persian Gulf and the 15th valid species of its genus.

Polypocephalus barami sp. 11 月,来自波斯湾的 Polypocephalidae Meggitt 新种,1924(Lecanicephalidea)。

引言 尽管波斯湾存在许多被称为 lecanicephalidean 绦虫的最终宿主的蝙蝠类物种,但该地区尚无关于该绦虫目的知识。这项研究是第一个关注波斯湾这一秩序的研究。方法 从波斯湾东北部收集了总共 11 条牛尾黄貂鱼,Pastinachus sephen (Forsskål)。分离的绦虫固定在 10% 海水缓冲的福尔马林中,并储存在 70% 乙醇中。对于形态学检查,蠕虫用醋酸胭脂红染色;为 SEM 准备了一个子集。结果 1878 年描述了一个新种 Polypocephalus Braun。Polypocephalus barami sp. 十一月 是其属内唯一在印度洋的日本、印度、斯里兰卡和埃及水域以外报道的物种。由于在多头鱼的通用诊断中没有描述微毛,因此根据标准化术语添加了对微毛的描述。此外,在Polypocephalus中讨论和比较了这个新物种的特征,其中许多物种的描述很差。结论 Polypocephalus barami sp。十一月 是波斯湾Polypocephalus属的第一份报告,也是该属的第15个有效物种。
