A new species of bitterling, Paratanakia haifengensis sp. nov. was collected from Guangdong Province in southern China is described in this study. P. haifengensis sp. nov. can be well distinguished from P. himantegus (Günther, 1868) and P. chii (Miao, 1934) based on the following morphological characters: (1) meristic counts: dorsal fin rays 3, 9; anal fin rays modally 3, 12; pectoral fin rays modally 1, 13; lateral-line scales modally 36; (2) specific longitudinal blue stripe on body side: the longitudinal blue stripe extending forward to the position below the third spine of dorsal fin in maximum and usually not exceeding the anterior margin of dorsal fin, its anterior tip inserted above the 13th-14th lateral-line scales; and (3) specific dorsal fin color pattern: dorsal fin with a broad shiny yellow stripe, and with an indistinct, very thin gray margin in male. In this study, the coloration, morphometric measurements and meristic features of P. haifengensis sp. nov. will be provided and the comparison of morphological characters between P. haifengensis sp. nov. and other species of Paratanakia will be discussed. In addition, a diagnostic key to all species of Paratanakia will be provided in this paper.
本研究描述了一种采自中国南方广东省的新物种——海丰副田中鳑鲏（Paratanakia haifengensis sp. nov.）。海丰副田中鳑鲏可以根据以下形态特征与细纹副田中鳑鲏（Paratanakia himantegus， Günther，1868）和纪氏副田中鳑鲏（Paratanakia chii，Miao，1934）很好地区分开来：（1）可数性状：背鳍条3，9；臀鳍条通常为3，12；胸鳍条通常为1，13；侧线鳞通常为36；（2）体侧特定的纵向蓝色条纹：纵向蓝色条纹向前延伸至最大不超过背鳍第三根硬棘下方的位置，通常不超过背鳍前缘，其前端插入第13-14枚侧线鳞上方；（3）特定的背鳍颜色模式：背鳍有一条宽阔的闪亮黄色条纹，雄性背鳍有不明显、非常细的灰色边缘。在本研究中，将提供海丰副田中鳑鲏的体色、形态测量和可数特征，并讨论海丰副田中鳑鲏与其他副田中鳑鲏物种之间的形态特征比较。此外，本文还将提供所有副田中鳑鲏物种的检索表。
