Notes on Scatonomus viridis walzi Pereira and Martínez, 1959

Pereira and Martínez (1959) described S. viridis walzi based on three females from Contrera , Paraguay. According to the original description, the subspecies may be distinguished from S. viridis viridis by the clypeus with a shallower central emargination, shorter clypeal teeth and sparser microsculpture on the head, pronotum and elytra. During the course of our revision, we could examine the female holotype of S. viridis walzi only through a low-quality photo of the dorsal habitus of the specimen. Pereira and Martínez (1959) stated that one paratype of their subspecies was deposited in the MZSP collection, but we could not find this specimen during our visit to the museum . Due to the limited material available for a more comprehensive comparative study of the subspecies comprising S. viridis , we opted to maintain the current taxonomic arrangement, in which S. viridis is divided into two subspecies, until more material becomes available for future studies.
