The current concept of Periophthalmus novemradiatus (Hamilton, 1822) includes two species. Procurement of fresh material and examination of extant type specimens revealed that P. novemradiatus differs from P. variabilis Eggert, 1935, primarily in the number of anal fin rays (I, 12 or 13 vs. I, 10-12); the lateral scale series (62-67 vs. 48-60); the extent of fusion of the pelvic fins (56.0-90.0% vs. 32.0-48.8%); and the patterns of the first and second dorsal fins.
目前对于九丝弹涂鱼（Periophthalmus novemradiatus，汉密尔顿，1822年）的概念包含两个物种。获取新鲜材料并检查现存模式标本后发现，九丝弹涂鱼与变色弹涂鱼（Periophthalmus variabilis，埃格特，1935年）的主要区别在于臀鳍鳍条数量（I，12或13对I，10 - 12）；侧线鳞列数（62 - 67对48 - 60）；腹鳍融合程度（56.0 - 90.0%对32.0 - 48.8%）；以及第一和第二背鳍的形态。
