Comparison: G. camposensis belongs to G. pilosoides group. The female of G. camposensis is similar to those of G. acutus (Olmi, 1984) and G. vannoorti Olmi, 2006 . The main differences are the following: in G. camposensis , anterior surface of metathorax + propodeum sculptured by many strong longitudinal striae; disc of metathorax + propodeum with a median longitudinal furrow; head very excavated ( Fig. 16 ); in G. acutus and G. vannoorti , anterior surface of metathorax + propodeum smooth, without sculpture, or granulated, or punctate, not sculptured by striae; disc of metathorax + propodeum without a median longitudinal furrow; head less excavated (Olmi 2006, figs 14, 15).
