Type series: Lectotype ♂ (designated by Génier & Vaz-de-Mello, 2002): BRAZIL: Paraná: Castro , 1926 ( BMNH)

Paralectotypes: Same data as lectotype (3 BMNH) .

Non-type material examined: BRAZIL: Minas Gerais: Belo Horizonte , XI-1950, A Machado (1 MZSP) ;

Diagnosis. Clypeal teeth absent (Fig. 68), as in G. bordoni . First elytral stria inconspicuous on anterior half, stria 2 well defined for entire length, striae 3–5 inconspicuous posteriorly, stria 6 completely inconspicuous. Parameres as in Fig. 69.

Distribution: Southeastern Brazil, Paraná Forest and Araucaria angustifolia Forest provinces of the Parana subregion ( Fig. 104).

Remarks: This rare species appears to be the sister taxon to G. bidens-margareteae ; the clypeal structure shared with G. bordoni is probably homoplasic.
