Heteragrion

description: Heteragrion Selys, 1862
Medium to large damselflies; the species in Ecuador are usually brown and black with yellow to yellowish orange markings (Fig. 43). Adults perch at an angle on stems and twigs mostly in shade or small sunny spots. Eight species have been recorded in Ecuador, but there is potential for undescribed species to be discovered as the genus is in need of revision. For identification see Williamson (1919), Lencioni (2005) and Vilela et al. (2019). Heckman (2008) is useful for narrowing down some of the choices but we advise caution in using this reference for this genus.

Note: This species is taxonomically very close to H. bariai. Heckman (2008) suggested that more research is necessary to resolve the relationship between the two taxa. We are retaining it as a distinct species pending further study. It was often referred to as “ Ecuador sp. B.”
