Two new species of bitterling of Paratanakia were found and collected from Taiwan island and Fujian Province, mainland China recently. Paratanakia fuvlidorsalis n. sp. which is endemic in Taiwan island can be well distinguished from other congeners by the following unique combination of features: (1) fin ray counts: dorsal fin rays 3, 8; anal fin rays 3, 10; pectoral fin rays modally 1, 12; (2) squamtion: lateral-line scales modally 34; and (3) its own specific dorsal fin color pattern in male. Paratanakia julongjiangensis n. sp. which is endemic in Fujian Province, mainland China can be well distinguished from other congeners by the following unique combination of features: (1) fin ray counts: dorsal fin rays 3, 9; anal fin rays 3, 11; pectoral fin rays modally 1, 12; (2) lateral-line scales modally 34; and (3) its own specific dorsal fin color pattern in male. The brief morphological comparison with close related species would be also addressed.
最近在台湾岛和中国大陆福建省发现并采集到了两种新的副田中鳑鲏属苦恶鱼。台湾岛特有的黑背副田中鳑鲏新物种可通过以下独特的特征组合与其他同属物种很好地区分：(1) 鳍条数量：背鳍条3, 8；臀鳍条3, 10；胸鳍条多数为1, 12；(2) 鳞片：侧线鳞多数为34；以及(3) 雄性特有的背鳍颜色模式。中国大陆福建省特有的巨龙江副田中鳑鲏新物种可通过以下独特的特征组合与其他同属物种很好地区分：(1) 鳍条数量：背鳍条3, 9；臀鳍条3, 11；胸鳍条多数为1, 12；(2) 侧线鳞多数为34；以及(3) 雄性特有的背鳍颜色模式。还将对与近缘物种的简要形态学比较进行阐述。
