Male genitalia: parameres ( Figs. 29 ); armature of the internal sac ( Figs. 60–61 ).

Note 1: Blackwelder (1944) was the first one to place G. pudibunda porteri Dallas, 1930 in synonymy with G. pudibunda . It is easy to see on the illustration of Dallas (1930) that G. pudibunda porteri is only a variation of one individual with an additional yellow spot on elytra.

Note 2: Practically all specimens from Buenos Aires (except five) are distinctive because of the larger, anterior black spot on the yellow margin of the elytra in contact with the central black area ( Figs. 17–18 ). In most specimens from Buenos Aires, the yellow color on the elytra is still more reduced ( Figs. 18 ). In the specimens from the remaining Argentinian provinces ( Fig. 63 ), the larger, anterior black spot on the yellow margin of the elytra is not fused but is separated from the central black area of the elytra ( Fig. 15 ).
