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).
通过对中国蝴蝶鱼科分类修订中的形态特征进行比较分析，发现了蝴蝶鱼科的一个新记录物种——角镰鱼。它与近缘物种尖嘴镰鱼的区别如下：背鳍通常有12根硬棘（vs. 11根）；上下颌各有2 - 3排牙齿（vs. 5 - 7排）；头部腹面轮廓凸起（vs. 几乎是直的）；臀鳍更呈角形，臀鳍后部的黑色区域通常向前延伸至最长软鳍条（vs. 更圆，通常不向前延伸至最长软鳍条）；吻部比眼睛短（vs. 更长）。
