| 摘 要： | 在对分布于中国的蝴蝶鱼科鱼类进行系统分类时,通过形态特征的比较分析,发现了蝴蝶鱼科的一个中国新记录种——多棘马夫鱼(Heniochus diphreutes Jordan)。新记录种与近缘种马夫鱼H.acuminatus (Linnaeus)]的主要区别为:背鳍鳍棘Ⅻ对Ⅺ;上下颌齿2～3排对5～7排;头部腹侧较圆钝对较平直;臀鳍较尖锐对较圆钝;臀鳍后部黑色横带向前延伸至最长鳍条,对未向前延伸至最长鳍条;吻长较短且小于眼径,对吻长较长且大于眼径。

| Abstract: | A new record species of Chaetodontidae,Heniochus diphreutes,was found by comparative analysis of the morphological characteristics in a taxonomic revision of the family Chaetodontidae in China.It was distinguished from its relative species H.acuminatus by a combination of the following:Dorsal fin usually with 12 spines(vs.11);2?3 rows of teeth on both jaws(vs.5?7);ventral profile of head convex(vs.almost straight);anal fin more angular,and black area on posterior part of anal fin usually extending anteriorly to longest soft ray(vs.more round,and usually not extending anteriorly to longest soft ray);and snout shorter than eye(vs.longer). |
