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. 22View FIGURE 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.
