. is described on the basis of 16 specimens from the Persian Gulf and Gulf of Oman, in the Northwest Indian Ocean. The new species can be distinguished from congeners by a combination of dorsal fin rays XII, 18-20, pectoral-fin rays 16-17, tubed lateral-line scales 55-57, gill rakers count (10-12 on the upper limb and 16-17 on the lower limb), 17-18 scales between the lateral line and the first anal-fin spine, 30-31 circumpeduncular scale rows and color pattern. is distinguished from by having the posterior margin of the opercular membrane grey (vs. red in ), fewer circumpeduncular scale rows, and a shorter base of the soft portion of the dorsal fin, 27.6-29.4% of standard length (SL) (vs. 31-32.3% of SL in ). The new species resembles but is differentiated from it by having more gill rakers, a smaller orbit diameter 27.5-32.1% of head length (HL) (vs. 35.5-37.2% of HL in ), a longer caudal peduncle 19.2-21.3% of SL (vs. 17.1-17.9% of SL in ), and the first to third pectoral-fin rays light gray (vs. dark gray in ). The new species can also be distinguished from the other species, including and , based on COI and Cyt molecular markers. The phylogenetic position of this new species indicates that it is a sister taxon of .
. 是根据来自印度洋西北部波斯湾和阿曼湾的16个标本描述的。新物种可通过以下特征组合与同属物种区分开来：背鳍鳍条为Ⅻ，18 - 20；胸鳍鳍条16 - 17；侧线管鳞55 - 57；鳃耙数（上肢10 - 12，下肢16 - 17）；侧线与第一臀鳍棘之间有17 - 18枚鳞片；围尾柄鳞行30 - 31以及体色模式。 与 不同之处在于，鳃盖膜后缘为灰色（ 为红色），围尾柄鳞行较少，背鳍软条部基部较短，为标准体长（SL）的27.6 - 29.4%（ 为SL的31 - 32.3%）。新物种与 相似，但与之不同的是，鳃耙更多，眼眶直径较小，为头长（HL）的27.5 - 32.1%（ 为HL的35.5 - 37.2%），尾柄较长，为SL的19.2 - 21.3%（ 为SL的17.1 - 17.9%），第一至第三胸鳍鳍条为浅灰色（ 为深灰色）。基于COI和Cyt 分子标记，新物种也可与其他物种，包括 和 区分开来。该新物种的系统发育位置表明它是 的姐妹分类单元。
