Description and habitat

It is a medium sized dragonfly with bottle-green eyes. Its thorax is black on dorsum, marked with yellow. There is a mesothoracic collar, oblique antehumeral stripes joined to the mesothoracic collar, and complete humeral stripes. Laterally yellow, with two black lines mapping out the sutures. The humeral stripes tapering to a point below, and black lines on lateral sutures rather thicker. Segment 1 of the abdomen is black, with a large lateral yellow spot. Segment 2 has a narrow basal black ring and broad sub-basal black stripes. Segments 3 to 6 have yellow basal rings and median dorsal spots. Segment 7 has its basal half yellow. Segment 8 and 9 are black, with a large yellow spot on each side. Segment 10 is entirely black. Superior anal appendages are yellow, the inferior is dark. Superiors have a fine black line along the upper surface of the apical third.[4]

No information available on the habitat or ecology of this species, but it is likely to breed in rocky forest streams as other species in this genus.[4]

gollark: I opened an instance to the internet for demo purposes, including to a bunch of esolang programmers, and it's actually overrun with self replicating notes now.
gollark: I have my own custom webapp for note taking which I never actually use. It's also stuck eternally at about 80% finished like all my programming projects.
gollark: Someone find me a line segment.
