Diagnosis: Surface shiny. Clypeal teeth long and acute, located bellow the surface of clypeal margin and separated of clypeal disc by strong and sharp carina (the clypeal central margin itself, which is centrally widely curved inwardly) (Fig. 60). Elytral striae with weak punctures. Elytral discal interstriae with either one or two rows of setose punctures. Parameres as in Fig. 61.

Distribution: Cerrado, Caatinga and Chaco provinces of the Chacoan subregion ( Fig. 105).

Remarks: This species is unusual in having either one or two rows of punctures on the discal interstriae; it is the most variable in size within the genus. It appears to be related to G. zanunciorum , with which it shares elongated clypeal teeth and shiny dorsal surface. The internal sac is unique by having a helicoid pseudoflagellum. Like G. bidens , this species is a common pastureland species, easily attracted to lights.
