Acanthopagrus latus, long considered a single valid Indo-West Pacific Ocean species, characterized by having yellow pelvic, anal and caudal fins, is reviewed and separated into A. latus (east Asian shelf) and Acanthopagrus longispinnis (Bengal Bay), and three new species: Acanthopagrus morrisoni sp. nov. (north-western Australia), Acanthopagrus arabicus sp. nov. [Middle East (except for the Red Sea) to coasts of Iran and Pakistan, and western Indian coast] and Acanthopagrus sheim sp. nov. (The Gulf). Although A. latus as redefined considerably varies in morphology and colouration, it can be recognized as a discrete east Asian endemic, with the following nominal species being junior synonyms: Chrysophrys auripes, Chrysophrys xanthopoda, Chrysophrys rubroptera and Sparus chrysopterus. Chrysophrys novaecaledoniae, known only from the holotype (type locality: Nouméa, New Caledonia), is a questionable junior synonym of A. latus, the lack of subsequent collections suggesting that the type locality is erroneous. Acanthopagrus longispinnis is differentiated from the other species in the complex by consistently having 12 dorsal-fin spines and a much larger second anal-fin spine, 21-26% (mean 23%) of standard length (LS ) (v. 14-24%, mean 18-21% in the other four species). Acanthopagrus morrisoni sp. nov. has the entire caudal fin yellow with a wide black posterior margin (persisting in preserved specimens) and consistently 3 ½ scale rows between the fifth dorsal-fin spine base and the lateral line. Acanthopagrus sheim sp. nov. has the pelvic, anal and lower caudal fins vivid yellow, with two (rarely three) small black blotches on the lower inter-radial membranes between the spinous and soft dorsal-fin rays. Acanthopagrus arabicus sp. nov. consistently has 4 ½ scale rows between the fifth dorsal-fin spine base and the lateral line, whereas A. latus always has black streaks proximally on the inter-radial membranes between the yellow anal-fin rays. A neotype and lectotye, respectively, are designated for A. latus and A. longispinnis. The p-distance (net nucleotide substitutions per site) of partial mitochondrial 16s ribosomal RNA genes (538 bp) among the above species (except A. longispinnis) and three other congeners (Acanthopagrus berda, Acanthopagrus pacificus and Acanthopagrus bifasciatus) strongly indicates that each is a distinct species. A key is provided for the 20 species of Acanthopagrus currently known from the Indo-West Pacific Ocean.
斜带石斑鱼，长期以来被认为是单一的有效印度洋-西太平洋物种，其特征是黄色的臀鳍、腹鳍和尾鳍，经过审查被分为斜带石斑鱼（东亚大陆架）和波纹唇鱼（孟加拉湾），以及三个新物种：莫氏斜带石斑鱼，新种（澳大利亚西北部）、阿拉伯斜带石斑鱼，新种[中东（红海除外）到伊朗和巴基斯坦沿海以及西印度沿海]和谢氏斜带石斑鱼，新种（波斯湾）。尽管重新定义的斜带石斑鱼在形态和颜色上有很大的差异，但它可以被认为是一个独特的东亚特有种，以下命名种是其初级同义词：黄鳍棘鲷、黄鳍鲷、黄鳍金眼鲷和黄鳍真鲷。仅知模式标本（模式产地：新喀里多尼亚努美阿）的新喀里多尼亚黄鳍棘鲷，是斜带石斑鱼的一个可疑的初级同义词，由于缺乏后续采集标本，表明模式产地是错误的。波纹唇鱼与该复合体中的其他物种的区别在于其背鳍鳍棘始终为 12 枚，第二根臀鳍鳍棘较大，为标准体长的 21-26%（平均值为 23%）（而其他四个种为 18-21%）。莫氏斜带石斑鱼的整个尾鳍呈黄色，后缘有宽的黑色边缘（在保存的标本中仍然存在），第五根背鳍鳍棘基部和侧线之间始终有 3 ½ 个鳞片行。谢氏斜带石斑鱼的臀鳍、腹鳍和下尾鳍呈鲜黄色，在硬棘和软条背鳍鳍条之间的下辐射膜上有两个（偶尔有三个）小黑斑。阿拉伯斜带石斑鱼的第五根背鳍鳍棘基部和侧线之间始终有 4 ½ 个鳞片行，而斜带石斑鱼的放射膜上通常有近端黑色条纹。斜带石斑鱼和波纹唇鱼分别被指定为模式种和正模种。除波纹唇鱼外，上述物种（波纹唇鱼除外）和其他三个近缘种（伯氏石斑鱼、太平洋石斑鱼和双带石斑鱼）的部分线粒体 16s 核糖体 RNA 基因（538bp）的 p-距离（每个位点的净核苷酸替换数）强烈表明，每个种都是一个独特的种。提供了一个用于鉴定西太平洋 20 种斜带石斑鱼的关键。
