Two Rare Species of Xarifia (Copepoda, Xarifiidae) New to Taiwan Parasitic on the Scleractinian Corals

首次在臺灣產石珊瑚上發現的二種罕見珊虱屬寄生橈足類(橈足類:珊虱科)

摘要


橈足類是一群廣泛存在於印度及太平洋海域石珊瑚體之內寄生蟲,我們調查了臺灣海域500株細枝鹿角珊瑚,共發現二種極為罕見的寄生性橈足類。它們分別為Humes (1985)在新喀里多尼亞發現的軛形珊虱(Xarifia jugalis)與五突珊虱(X. quinaria)。這二種寄生蟲全部均為臺灣及北太平洋新紀錄種,本篇報告詳細的描述蟲體各附屬肢之形態學特徵並討論不同地理區上的特徵差異。

並列摘要


Xarifiid copepods are one of the most common endo-parasites of scleractinian corals in the tropical Indo-Pacific. In this study, two rare species of xarifiid copepods, Xarifia jugalis Humes, 1985 and X. quinaria Humes, 1985, were discovered from 500 colonies of Pocillopora damicornis (Linnaeus, 1758). Both of them are not only new to Taiwan but also new to the waters of North Pacific. A full description of these 2 species is provided to show the possible geographical variations of their morphology.
