Cylindrostethus Fieber, 1861 is one of the most striking genera of water striders (Insecta: Hemiptera: Gerridae) and has Pantropical distribution. Members of this group can be recognized by the very long, cylindrical body; the short antennomere IV; the short labium not reaching the mesosternum; and by characteristics of the abdomen of males and females. Although Neotropical representatives of the genus have been revised, there are pending taxonomic issues related to this fauna, and that of the Eastern Hemisphere has been barely studied in recent years. Here, we present a short note about the authorship of Cylindrostethus, an updated key to all species of the genus, a new synonymy, and the description of a previously unknown macropterous male of C. hungerfordi Drake and Harris.
圆柱豉蝽属（Cylindrostethus Fieber, 1861）是豉蝽科（Hemiptera: Gerridae）中最引人注目的属之一，分布于泛热带地区。该属的成员可以通过非常长的圆柱形身体、短的第四触角节、未到达中胸的短唇、以及雄性和雌性腹部的特征来识别。虽然已经对新热带地区的该属代表进行了修订，但仍存在与该动物群相关的待分类问题，而且近年来对东半球的该属研究甚少。在这里，我们对圆柱豉蝽属的命名人进行了简短的说明，提供了该属所有物种的最新修订版关键特征、一个新的同物异名，并描述了一个以前未知的大型雄性饥饿氏圆柱豉蝽（C. hungerfordi Drake and Harris）。
