Ceratomyxa parasites from the gall bladders of 23 species of cardinalfishes (family Apogonidae) from Australian waters were examined for their taxonomic identity and phylogenetic relatedness. We identified 15 of the 23 apogonid fish species infected with species of Ceratomyxa. Although the majority of apogonid species harboured only a single Ceratomyxa species, four were found with multiple species of Ceratomyxa. This study describes eight novel species using a combination of morphological, small subunit ribosomal DNA (SSU rDNA) and biological characters. Six Ceratomyxa species are reported from single apogonid species, while two are reported from multiple host species. Molecular data were critical in identifying several morphologically cryptic species. However, our results suggest that SSU rDNA was not capable of distinguishing all the species present in the current study system and alternative genetic markers should be investigated in the future.
对采自澳大利亚海域23种天竺鲷（天竺鲷科）胆囊中的尾孢虫寄生虫进行了分类鉴定和系统发育相关性研究。我们在23种天竺鲷中鉴定出15种感染了尾孢虫。虽然大多数天竺鲷物种仅感染一种尾孢虫，但发现有4种感染了多种尾孢虫。本研究结合形态学、小亚基核糖体DNA（SSU rDNA）和生物学特征描述了8个新物种。6种尾孢虫是从单一的天竺鲷物种中发现的，而2种是从多个宿主物种中发现的。分子数据对于鉴定几种形态上难以区分的物种至关重要。然而，我们的结果表明，SSU rDNA无法区分当前研究系统中存在的所有物种，未来应研究其他遗传标记。
