摘要:

本研究检视了采自中国沿海的银口天竺鲷属标本314尾, 形态学鉴定为8种: 斑鳍银口天竺鲷(Jaydia carinata (Cuvier, 1828))、细条银口天竺鲷(J. lineata (Temminck & Schlege, 1842))、新几内亚银口天竺鲷(J. novaeguineae (Valenciennes, 1832))、黑鳃银口天竺鲷(J. poeciloptera (Cuvier, 1828))、史密斯氏银口天竺鲷(J. smithi Kotthaus 1970)、横带银口天竺鲷(J. striata (Smith & Radcliffe, 1912))、印度洋银口天竺鲷(J. striatodes (Gon, 1997))和黑边银口天竺鲷(J. truncata (Bleeker, 1854))。结合GenBank中的同种序列, 对史密斯氏银口天竺鲷进行DNA条形码分析, 发现中国群体和地中海群体分为两个组群, 两者平均组间遗传距离为0.044, 表明其中存在隐存种。因该种模式产地为亚丁湾, 推测中国种群为隐存种Jaydia sp.。结合标本和文献考证, 我们认为中国已知有银口天竺鲷属鱼类9种, 未采集到的烟台银口天竺鲷J. tchefouensis (Fang, 1942)可能为J. lineata次定同种异名。我们整理了各种的同种异名、形态特征和地理分布, 编制了检索表, 探讨了分类问题, 修订了错误。中国已记录物种J. elliotiJ. arafuraeJ. albomarginata实际为J. truncataJ. poecilopteraJ. novaeguineae

Abstract

Aim: Cardinalfishes (Apogonidae) are one of the numerically dominant reef fish families. The taxonomy of cardinalfish genus Jaydia in China was unclear for a long time. This study aims to revise the the taxonomy of the genus from China.
Methods: The taxonomic revision was based on comprehensive examination of specimens and review of literatures. Jaydia sp. was distinguished from J. smithi by molecular comparison.
Results: Eight species were identified morphologically, including Jaydia carinata (Cuvier, 1828), J. lineata (Temminck & Schlege, 1842), J. novaeguineae (Valenciennes, 1832), J. poeciloptera (Cuvier, 1828), J. smithi Kotthaus 1970, J. striata (Smith & Radcliffe, 1912), J. striatodes (Gon, 1997), J. truncata (Bleeker, 1854). But J. tchefouensis was not found from China seas. The results of molecular analysis of J. smithi showed the Chinese population and the Mediterranean population formed two exclusive lineages which have obvious interspecific-level mean genetic distance (0.044). The previously recorded species from China, J. ellioti, J. arafurae, J. albomarginata, and J. smithi, should be revised as J. truncata, J. poeciloptera, J. novaeguineae, and Jaydia sp., respectively. Jaydia tchefouensis may be a junior synonym of J. lineata. The synonyms, distribution, morphological diagnosis and description, and a key to species were provided. The taxonomic problems were also discussed.
Conclusion: Nine Jaydia species were recognized from China. Our results will promote the taxonomic study of family Apogonidae.
