Sanborn (2016a) summarized the history and synonymy of the various species now considered to be G. bicolor. The short, stocky species with the body about half as wide as it is long (body lengths range from 19–23 mm) is unique among the species of Guyalna and can be separated quickly from other members of the genus. The name is in reference to the bright green head and thorax (fading or chemically altered to ochraceous in some specimens) and castaneous or testaceous abdomen. The wings are completely hyaline and lateral abdominal tergites 2–4 are often covered with areas of dense silvery pile. Distribution.
