Mesamphiagrion Kennedy, 1920

Two of the fourteen species are recorded for Ecuador, and there is possibly a third yet unknown species. Adults are small to medium in size and usually are black with blue markings (Fig. 23), although young individuals are black and red. For identification, see von Ellenrieder & Garrison (2008a). They breed in small pools of open marshy seepage at high elevations.
