( Figs. 6 , 33 )

Diagnosis. Eulissus chalybaeus may be recognized among other southern South American Xantholinini by its body large and robust, the head, pronotum, elytra and abdomen of metallic color (blue, green or violet) and the pronotal disc impunctate except near margins. Length 28–35 mm.

Distribution. From Mexico to Argentina ( Márquez & Asiain 2002).
