Etymology: Trigonectes:Greek, trygon = a sting ray + Greek, nekton = swimmer (Ref. 45335); rubromarginatus:From the Latin ruber (red) and marginatus (with margin), referring to the red stripe along the ventral margin of the caudal fin (Ref. 26656). More on author: Costa.
背的软条 (总数) : 10 - 14; 臀鳍软条: 16 - 18. Distinguished from other species of the genus, except T. strigabundus, by having straight mouth cleft. Differs from T. strigabundus and all other species of the genus by the elongated pelvic fin of the males, whose tip is reaching to the base of 11th to 15th anal rays and the presence of a bright red stripe along the ventral margin of the male caudal fin. Seems to differ from T. strigabundus by having a larger size (Ref. 26656).
与其他种的本属区分了, 除 T. strigabundus, 借着具有直的嘴裂缝。 有别于 T. strigabundus 与所有的其他种的本属藉由延长雄性的腹鳍, , 顶端正在延伸到第 11 到第 15个臀鳍鳍条的基底与那有一条鲜红色斑纹沿着雄鱼尾鳍的下缘。 似乎藉由有一个不同于 T. strigabundus 较大。 (参考文献 26656)
