Male genitalia: parameres ( Fig. 73 ).

Note 1: The mention of G. schistacea from Santiago del Estero by Burmeister (1866), repeated by Bruch (1911a), corresponds to the specimen of Gymnetis bruchi and not to the specimen from the Breyer Colletion, which was incorporated to the MACN after 1930.

Note 2: Schenkling (1921: 93) listed G. schistacea as a synonym of G. flaveola based on Kraatz (1888), but Schürhoff (1937) later treated it as a subspecies of G. flaveola . Gymnetis schistacea seems to be a color variation (Fig. 69) of G. flaveola (Figs. 70–71).

Note 3: The male parameres of G. flaveola ( Fig. 72 ) are slightly different from those of G. schistacea ( Fig. 73 ).
