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.ellioti、J.arafurae、J.albomarginata实际为J.truncata、J.poeciloptera和J.novaeguineae。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.
