Remarks. Sanborn (2016a) describes the history and synonymy of the numerous species that are now considered G. bicolor . It is a short, stocky species being about half as wide as long (body lengths range from 19–23 mm). The name is in reference to the green (fading to ochraceous in some specimens) head and thorax and castaneous or testaceous abdomen. There are often areas of dense silvery pile on the lateral abdominal tergites 2–4.

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; 2014; 2016a; 2016b; Sanborn & Maes 2012; Maes et al. 2012). It was reported as being collected in Panama by Wolda & Ramos (1992) but without locality data.
