Triacanthagyna
Selys, 1883
Of the nine species in this genus, five occur in
Ecuador
. Adults are mainly dark green and black and are relatively slender and small compared to most aeshnids (
Fig. 68
); they are crepuscular, sometimes flying at treetop level just before dark. Small, temporary, rainforest pools and tree holes are the preferred habitat. References are
Williamson (1923a)
and
von Ellenrieder & Garrison (2003)
.

Note:
von Ellenrieder & Garrison (2003)
suggest that “the apparently disjunct distribution may be due to the species being rare and more though collecting will show it to occur in intermediate localities.”
