Three ischnuran spp. have an unusual “scoop” structure on their accessory penes. They represent the genera Celaenura and Nanosura, constructed by C.H. KENNEDY (1920, Ohio J. Sci. 21: 83-88) when he split the genus Ischnura. His hypothesis is based on other characters. Scanning electron micrographs of this character are provided. This character provides support for Kennedy’s argument.
