A new species of the roughy fish genus Hoplostethus is described from 11 types and a non-type specimen collected from Taiwanese waters. It can be distinguished from its congeners by a combination of characters: pectoral-fin rays 14-17 (modally 15-16); pyloric caeca 65-84; total gill rakers 19-20; predorsal scales 18-22; oral cavity, branchial chamber, top and underside of tongue, and peritoneum uniformly black; distal margin of membrane between dorsal-fin spines black; caudal fin without a black margin; caudal-fin base brownish. Comparisons of the new species with similar species are provided. DNA barcoding supports the monophyly of the new species, which appears to be closely related to Hoplostethus japonicus [average cytochrome c oxidase subunit I Kimura-2-parameter (COI K2P) distance of 4.1%].
本文描述了来自台湾水域的 11 个模式和非模式标本的一种新的糙鲈属鱼类。它可以通过以下特征组合与同属鱼类区分开来：胸鳍鳍条 14-17（模式为 15-16）；幽门盲囊 65-84；总鳃耙 19-20；背鳍前鳞 18-22；口腔、鳃腔、舌顶和底、腹膜均为黑色；背鳍刺之间膜的远缘为黑色；尾鳍无黑色边缘；尾鳍基部呈褐色。本文还提供了与相似物种的比较。DNA 条形码支持新物种的单系性，它似乎与日本糙鲈（平均细胞色素 c 氧化酶亚基 I Kimura-2-参数（COI K2P）距离为 4.1%）关系密切。
