Triatoma protracta is a species of any mid sized insect in the family Reduviidae.
[3] This species and other "kissing bugs" are vectors of Trypanosoma cruzi, the protozoan that causes Chagas disease.
It is dark brown to black in color with a lighter margin along the abdomen.
The nymph is similar in appearance but it is smaller and lacks wings.
They bite humans, producing irritation to the skin and sometimes severe allergic reactions.
