Two new species of perchlets are described, collected from mesophotic coral ecosystems in French Polynesia and the Republic of the Marshall Islands, in the tropical Central Pacific. was collected at a depth of 105 m in Tahiti, French Polynesia, and 120 m in Maloelap Atoll, Republic of the Marshall Islands. It was also observed in Moorea and Rangiroa (French Polynesia), and at Majuro and Erikub Atolls, Republic of the Marshall Islands. was collected at a depth of 90-98 m in Tahiti, French Polynesia, and observed in Moorea. The barcode fragment of the cytochrome oxidase I gene of does not closely match any published sequence of , with approximately 15% uncorrected divergence from several species. can be distinguished from all of its congeners by coloration and morphology. The barcode fragment of the COI gene of is closest to , with 5.4% uncorrected divergence. is also distinguished from all of its congeners by morphology, and a coloration that includes two indistinct black spots along the base of the dorsal-fin, and transparent yellow dorsal and anal fin membranes. With this publication, the genus now comprises 58 valid species, with representatives from tropical to temperate waters of the Atlantic, Pacific, and Indian oceans. These two new discoveries add to the growing body of research highlighting the rich biodiversity of mesophotic ecosystems.
描述了两种新的天竺鲷科鱼类，它们采集自热带中太平洋法属波利尼西亚和马绍尔群岛共和国的中光层珊瑚生态系统。[此处原文缺失具体物种名，无法准确翻译] 在法属波利尼西亚塔希提岛105米深处以及马绍尔群岛共和国马洛埃拉普环礁120米深处被采集到。在莫雷阿岛和朗伊罗阿岛（法属波利尼西亚）以及马朱罗和埃里库布环礁（马绍尔群岛共和国）也有发现。[此处原文缺失具体物种名，无法准确翻译] 在法属波利尼西亚塔希提岛90 - 98米深处被采集到，并在莫雷阿岛被观察到。[此处原文缺失具体物种名，无法准确翻译] 的细胞色素氧化酶I基因的条形码片段与已发表的任何**[此处原文缺失具体物种名，无法准确翻译]** 序列都不太匹配，与几个物种的未校正差异约为15%。[此处原文缺失具体物种名，无法准确翻译] 可以通过颜色和形态与所有同属物种区分开来。[此处原文缺失具体物种名，无法准确翻译] 的COI基因的条形码片段与**[此处原文缺失具体物种名，无法准确翻译]** 最接近，未校正差异为5.4%。[此处原文缺失具体物种名，无法准确翻译] 也通过形态以及包括沿背鳍基部有两个不明显黑点和透明黄色背鳍与臀鳍膜的颜色与所有同属物种区分开来。随着本出版物的发表，[此处原文缺失属名，无法准确翻译] 属现在包括58个有效物种，分布于大西洋、太平洋和印度洋从热带到温带的水域。这两项新发现增加了越来越多强调中光层生态系统丰富生物多样性的研究成果。
