简单描述

背棘 (总数) : 1; 背的软条 (总数) : 6; 臀鳍软条: 14 - 15. Shallow midlateral plates covering less than or equal to 1/4 body depth. Anterior nuchal plate usually of moderate width (longer than wide) permitting weak to firm suture between supraoccipital and middle nuchal plate. Also differs from all species of Leptodoras except L. copei by possessing a distal tip of lower labial extension extending beyond that of upper labial extension (Ref. 56896).
Body shape (shape guide): elongated.
水浅的侧面中央的碟覆盖少于或者等于 1/4个体高。 前面的颈背碟通常允许的中等宽度 (长度超过宽的) 弱的对在上枕骨与中央的颈背碟之间的结实缝合。 藉由持有上面唇的延长延伸超过那的一个低唇的延长末端除了 L. copei 以外也有别于 Leptodoras 的所有种。 (参考文献 56896)
