We describe the new genus Pehuencoris to include P. gurguliophagus n. sp. from southern Argentina and Chile (Patagonia). We illustrate the dorsal habitus and male genitalia, provide a complete description of the ostiolar peritreme and its microsculpture, and show a distributional map. We include comments on the biology and habits of the new species, and discuss relationships of the new genus to other genera of Cardiastethini.
