背棘 (总数) : 0; 背的软条 (总数) : 10 - 11; 臀棘: 0; 臀鳍软条: 9; 脊椎骨: 33. Possess a tubular gonopodium with shortened second, fourth and fifth anal fin rays, an enlarged seventh middle anal fin radial in males and females, and an elongate dorsoposterior process of the lacrimal. Branchiostegal rays: 5. Distinguished from other Plesiojenynsia by the following combination of characters: a single midlateral stripe without associated dorsolateral or ventrolateral stripes or blotches in adults; a terminal to slightly oblique mouth; fewer than 13 gillrakers; and absence of the first mandibular-canal pore.
持有一个管状的生殖足有变短的第二个，第四的与第五个臀鳍棘条, 在雄性与雌性 , 与泪骨的一个细长后背突起中的一个增大的第七个中央的臀鳍动脉。 鳃条骨: 5. 在组合特徵之后与其他的 Plesiojenynsia 区分了藉由: 当成鱼时的没有相连的背外侧或腹侧的斑纹或斑块的一条侧面中央的斑纹; 一个端位到些微斜的嘴; 少于 13个鳃耙; 而且缺乏第一个颚骨管孔。
