Centrorhynchus globocaudatus (Zeder, 1800) Lühe, 1911 (Centrorhynchidae) was reported in birds of prey. Our population from Falco tinnunculus Linnaeus (Falconidae) and Buteo buteo Linnaeus (Accipitridae) in northern Italy was morphologically distinct from others described elsewhere. The worms are elongate and cylindrical. Proboscis long, apically truncated and bare, with wider base and variably faint constriction at point of attachment of receptacle. Large anterior hooks well rooted; posterior spiniform hooks with reduced roots; transitional hooks with scutiform roots in-between. Four tubular cement glands extend into prominent ducts overlapping a large Saefftigen's pouch. Bursa large, with sensory plates. Vagina with laterally slit orifice in sub-ventral pit of globular terminal extension. Thick-shelled eggs ovoid without polar prolongation of fertilization membrane. In our specimens, proboscis hooks, receptacle, male reproductive system, and lemnisci especially in males varied in size from those from Ukraine, India, Egypt, Kyrgystan, Russia, Georgia, Armenia and Asian Soviet Republics. Our description of the Italian specimens includes new morphological information supported by scanning electron microscopy and microscope images, molecular analysis and energy dispersive X-ray analysis (EDXA) of hooks. Additional new details of proboscis hook roots, micropores and micropore distribution are described. Metal composition of hooks (EDXA) demonstrated high levels of calcium and phosphorous, and high levels of sulphur in core and cortical layers of eggs. The molecular profile based on sequences of 18S and cytochrome c oxidase 1 genes is also provided, as well as phylogenetic reconstructions including all available sequences of the family Centrorhynchidae, although further sequences are needed in order to clarify their phylogenetic relationships.

来自 Falco tinnunculus (Falconidae) 和 Buteo buteo (Accipitridae) 的意大利 Centrorhynchus globo caudatus (Zeder, 1800) Lühe, 1911 (Acanthocephala: Centrorhynchidae) 种群的描述和分子分析

圆尾尖嘴鱼(Zeder, 1800) Lühe, 1911 (Centrorhynchidae) 在猛禽中被报道。我们的人口来自隼林奈（隼科）和鲶鱼意大利北部的林奈 (Accipitridae) 在形态上与其他地方描述的其他物种不同。蠕虫是细长的和圆柱形的。喙长，顶端截断和裸露，基部较宽，在花托附着点处有不同程度的微缩。大前钩扎根良好；后棘状钩，根减少；中间有盾状根的过渡钩。四个管状水泥腺体延伸到突出的导管中，与一个大的 Saefftigen 袋重叠。法氏囊大，有感觉板。阴道在球状末端延伸的腹下凹处有横向狭缝孔。厚壳卵卵形，受精膜无极延长。在我们的标本中，长鼻钩、容器、雄性生殖系统和 lemnisci 尤其是雄性的大小与乌克兰、印度、埃及、吉尔吉斯斯坦、俄罗斯、格鲁吉亚、亚美尼亚和亚洲苏维埃共和国。我们对意大利标本的描述包括扫描电子显微镜和显微镜图像支持的新形态信息、钩子的分子分析和能量色散 X 射线分析 (EDXA)。描述了长鼻钩根、微孔和微孔分布的其他新细节。鱼钩的金属成分 (EDXA) 显示鸡蛋的核心层和皮质层中钙和磷含量高，硫含量高。基于 18S 和细胞色素序列的分子谱 钩子的分子分析和能量色散 X 射线分析 (EDXA)。描述了长鼻钩根、微孔和微孔分布的其他新细节。鱼钩的金属成分 (EDXA) 显示鸡蛋的核心层和皮质层中钙和磷含量高，硫含量高。基于 18S 和细胞色素序列的分子谱 钩子的分子分析和能量色散 X 射线分析 (EDXA)。描述了长鼻钩根、微孔和微孔分布的其他新细节。鱼钩的金属成分 (EDXA) 显示鸡蛋的核心层和皮质层中钙和磷含量高，硫含量高。基于 18S 和细胞色素序列的分子谱C还提供了氧化酶 1 基因，以及系统发育重建，包括 Centrorhynchidae 家族的所有可用序列，尽管需要进一步的序列来阐明它们的系统发育关系。
