Kudoid parasites are significant pathogens of marine fish. In the past, specific identification has been difficult due to a paucity of detailed morphological and biological information provided in the original description of some species. However, the introduction of DNA analysis has dramatically improved diagnosis. For morphological characterization, this paper proposes a new set of schematics including additional measurements to give a more thorough description of spore morphology, and provides evidence for uniqueness of 4 new species: Kudoa gunterae n. sp. (from 10 pomacentrid species and 1 apogonid species), K. kenti n. sp. (from 4 pomacentrid species), K. paraquadricornis n. sp. (from 4 carangid species), and K. whippsi n. sp. (from 8 pomacentrid species and 1 apogonid species). Subtle morphological differences found between closely related species were reflected in their genetics, with increased resolution provided by the large subunit, compared with that of the small subunit, of the ribosomal DNA gene region. This article proposes comprehensive requirements for species descriptions within the Kudoidae that incorporate biology, morphology, and genetic sequence.
Kudoid 寄生虫是海洋鱼类的重要病原体。过去，由于一些物种的原始描述中提供的详细形态学和生物学信息较少，因此特定鉴定一直很困难。然而，DNA 分析的引入极大地改善了诊断。对于形态特征，本文提出了一套新的示意图，包括附加的测量值，以更全面地描述孢子形态，并为 4 个新物种的独特性提供证据：Kudoa gunterae n. sp.（来自 10 种雀鲷和 1 种刺尾鱼科鱼类）、K. kenti n. sp.（来自 4 种雀鲷）、K. paraquadricornis n. sp.（来自 4 种鲹科鱼类）和 K. whippsi n. sp.（来自 8 种雀鲷和 1 种刺尾鱼科鱼类）。在亲缘关系密切的物种之间发现的细微形态差异反映在它们的遗传学上，与核糖体 DNA 基因区域的小亚基相比，大亚基提供了更高的分辨率。本文提出了 Kudoidae 内物种描述的综合要求，包括生物学、形态学和遗传序列。
