A not uncommon damselfly found in the thick vegetation of swamps and 
marshes. Labrum greenish-yellow with the base black. Pale postocular spots 
small, circular and isolated. Mouth parts, genae, postgenae, anteclypeus and 
the vertical portion of the frons, pale. Postclypeus, antennae, horizontal portion 
of the frons, vertex and the occiput, black. Dorsum of the prothorax black with 
a pale spot on the anterior lobe and the sides pale. Thoracic dorsum black, the 
pale, antehumeral stripe interrupted in its middle length by a fusion of the black 
middorsal and humeral stripes, to form a pale exclamation point mark on either 
side. Sides greenish-yellow except for a black basal spot on the second lateral 
suture and a heavy black stripe covering the third lateral suture. Dorsum of 
abdominal segments 1-10 black, except for narrow interrupted basal rings of 
yellow on segments 3-7, and apical crescent-shaped half rings of blue on the 
dorsum of 8-9. 
Female. Color pale blue and black, no heterochromatic phase known. Head 
similar to that of the male. Thorax lacking the black stripe on the metapleural 
suture, and occasionally having the pale antehumeral stripe complete, not 
interrupted to form an exclamation mark. Abdomen like the male. No ventral 
spine on the apical margin of abdominal segment 8.

widens suddenly just posterior to the mesinfraepisternum which it covers; a very
