description: Leptobasis Selys, 1877
Small to medium slender damsefllies, only two of the nine species being found in Ecuador; undetermined specimens also exist in collections that could represent an undescribed species. The thorax usually has green stripes and the slender, elongate abdomen is often orange or yellowish (Fig. 22). See Garrison & von Ellenrieder (2010) and Johnson (2016) for identification. The Ecuador species inhabit open to partly shaded shallow marshes and the edges of small slow streams.

Note: Kennedy (1919) recognized that “the species (of Leptobasis labeled vacillans) in the Cornell University collection from Ecuador appears to be entirely new and have long forcipate inferiors.” He showed figures of the Cornell specimen genital ligula.
