Dubious record

ARGENTINA: Misiones: A. Breyer Collection, 2 exx. [ MACN] ; 1 ex. [ MACN], labeled “ Gymnetis / flavomarginata / Blanch. R.A.A.M. col.”; 1 ex. [ MACN], labeled “ Gymnetis / flavomarginata / Blnch. / Dr. Dallas determ.” .

Male genitalia: parameres ( Fig. 38 ).

Note 1: Burmeister (1861, 1943) mentions that he found “the G. flavormarginata Bl. D’Orb. from Corrientes in Santiago ” (translated from Spanish). This specimen belongs to G. bouvieri .

Note 2: Burmeister (1861, 1943) also mentioned that he found in Catamarca, “other similar (to G. flavomarginata Blanchard, [1842] ) but different and smaller” (translated from Spanish). In 1866, Burmeister gave a brief description of this insect as a variety of G. flavomarginata : “a minor variety, instead of the eight big spots of pure yellow color, it has eight small orange spots, which are neither confluent nor prolongued in teeth” ( Fig. 30 ). The male genitalia of one of these specimens is identical to typical G. bouvieri from Santiago del Estero ( Fig. 38 ).

Note 3: Lists of publications by Dallas were given by Pirán (1946, 1954) and De Santis (1992). Apparently Gymnetis pudibunda var. minor was not published. Therefore, the specimen at MLPA is not a type specimen.

Note 4: In two specimens from La Rioja (Breyer Collection), the internal margin of the yellow elytral band is straight and parallel to the elytral margin.

Note 5: Antoine (2001) mentioned six males from Pozo La Gringa (Chaco), comprising 1 ex. of the typical form, 3 exx. with reduced spots on the elytra, and 2 exx. without spots.
