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.
