Oxyagrion Selys, 1876

Only one species of this relatively large genus of 25 species occurs in Ecuador. Adults are small and are usually mostly red, rarely with blue on head and tip of abdomen ( Fig. 27 ). See Mauffray (1999) and von Ellenrieder & Lozano (2008) for identification and diagnoses. Habitat in Ecuador is mainly small seeps and slow stream edges at high elevations.

Note: Before being described, this species was thought to be a form of Oxyagrion bruchi Navás, 1924 . So far found only in a limited area on the east slope of the Andes in Ecuador. Specific locality information on many of these records can be found in Mauffray (1999).
