Based on two males from Ecuador (Sucumbos Province), Paracordulia calcarulata sp. nov. is the second described species of the genus. This new species is compared to P. sericea (Selys, 1871). The different shape of the anal appendages easily allows separation of the two. Generic diagnosis based on adults and larvae is amended. Paracordulia Martin, 1907 is a poorly known genus of the Amazonian biome, and its apparent rarity or absence of records is probably due to its secretive habits; considering the different forms of known females, its specific diversity has likely been significantly underestimated. Some structures of the vesica spermalis are briefly discussed.
基于来自厄瓜多尔（苏昆博斯省）的 2 只雄性个体，新种尖尾副 cordulia 是该属的第二种被描述的物种。这种新物种与 P. sericea（Selys，1871）进行了比较。肛附器的不同形状很容易将两者区分开来。对基于成虫和幼虫的属诊断进行了修订。Paracordulia Martin，1907 是亚马逊生物群中一个鲜为人知的属，其明显的稀有或缺乏记录可能是由于其隐秘的习性所致；考虑到已知雌性的不同形态，其特有多样性很可能被大大低估了。简要讨论了精荚的一些结构。
