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).
