A new species of (Teleostei, Pomacentridae) is described from four specimens collected between 95 and 110 m depth in mesophotic coral ecosystems in the Maldives, Indian Ocean. can be distinguished from all of its congeners by the following combination of characters: dorsal-fin rays XIII, 12-13; anal-fin rays II,11-12; pectoral-fin rays 17-18; tubed lateral-line scales 17; gill rakers 7+17-18 = 24-25; pearly white body with a large black marking covering the anterior two-thirds of the anal fin. The closest DNA barcode sequence (5.1% average uncorrected genetic distance on the mitochondrial gene), among those available, is , a similar mesophotic species known from the coastal western Indian Ocean (Somalia to South Africa). The new species is easily distinguished from by having 13 dorsal spines (versus 14 in ), the absence of a black band on the base of the tail (present in ), and by the genetic difference.
一种新的雀鲷科（硬骨鱼纲）物种，根据在印度洋马尔代夫中光层珊瑚生态系统95至110米深处采集的四个标本进行描述。该物种可通过以下特征组合与所有同属物种区分开来：背鳍鳍条为XIII、12 - 13；臀鳍鳍条为II、11 - 12；胸鳍鳍条为17 - 18；有管侧线鳞17；鳃耙7 + 17 - 18 = 24 - 25；身体呈珍珠白色，有一大块黑色斑纹覆盖臀鳍前三分之二。在所提供的DNA条形码序列中，最接近的（线粒体基因上平均未校正遗传距离为5.1%）是，一种在印度洋西部沿海（索马里至南非）已知的类似中光层物种。该新物种与通过具有13根背棘（相比有14根）、尾基部无黑色带（中有）以及遗传差异而容易区分。
