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

DISTRIBUTION. The species has been reported under the various synonyms from Brazil Colombia, Costa Rica, French Guiana, Nicaragua, and Panama ( Metcalf 1963a; Duffels & van der Laan 1985; Sanborn 2011a; 2013; 2014a; 2016a, b; 2018b; Sanborn & Maes 2012; Maes et al. 2012).
