摘要

刺头虫属（Longicollum Yamaguti）， 1935年，目前包括12种鱼类寄生物种。除l.p agrosomi Yamaguti， 1935外，其余11个同系物尚未进行分子系统发育研究。在台湾和日本的咸淡鱼和海鱼中发现了长颈（Longicollum alemniscus, Harada, 1935），但其形态尚不清楚。本文对其形态进行了重新描述，并对其在Pomphorhynchidae中的系统发育位置进行了推测。此外，我们总结了Longicollum的形态特征，以区分其与形态相似的Paralongicollum属Amin， Bauer, and Sidorov, 1991。

Morphological and Molecular Characteristics of Longicollum alemniscus (Acanthocephala: Echinorhynchida), with a Taxonomic Revision of the Genus Longicollum.

The acanthocephalan genus Longicollum Yamaguti, 1935 currently comprises 12 fish-parasitic species. Except for L. pagrosomi Yamaguti, 1935, the remaining 11 congeners have not been the subject of molecular phylogenetic studies. Longicollum alemniscus (Harada, 1935) has been found in brackish and marine fish in Taiwan and Japan, but its morphology remains inadequately understood. In this paper, we provide a morphological redescription and infer the phylogenetic position of L. alemniscus within the Pomphorhynchidae. Furthermore, we summarize the morphological characteristics of Longicollum to distinguish it from the morphologically similar genus Paralongicollum Amin, Bauer, and Sidorov, 1991.

期刊介绍： Zoological Science is published by the Zoological Society of Japan and devoted to publication of original articles, reviews and editorials that cover the broad field of zoology. The journal was founded in 1984 as a result of the consolidation of Zoological Magazine (1888–1983) and Annotationes Zoologicae Japonenses (1897–1983), the former official journals of the Zoological Society of Japan. Each annual volume consists of six regular issues, one every two months.
