在已知的17种Cincticostella属植物中，仅有5种同时为稚虫和象虫，这还不包括中国的C. fusca Kang et Yang（1995）。在这里，仙女被重新描述和饲养图像首次报道。基于从中国东南部收集的材料。在形态上，若虫是独特的，因为它的体型大，扩大的属，头部前部的中间白色条纹，深色跗骨。雄象的体型大，前翅有色素，胸椎胸骨有一对膜状片，可与同类区分开来。更重要的是，它的喙是独特的，它们的大部分长度是融合的，并且有复杂的腹突。成虫在早春（3月至4月）产卵。
Among the 17 known species of the genus Cincticostella, only five of them have been reported as both nymphs and imagoes, which does not include the Chinese species C. fusca Kang et Yang (1995). Here the nymphs are redescribed and reared imagoes are reported for the first time. based on material collected from southeastern China. Morphologically, the nymph is unique because of its large body size, expanded genae, pale median stripe on the anterior of the head, and dark tarsi. The male imago can be differentiated from congeners by its large body size, pigmented forewings, and the mesothoracic scutellum having a pair of membranous lamellae. More importantly, its penes are distinct, being fused for most of their length and having complex ventral projections. Adults emerge in early spring (March to April).
