The genus Aporius Kuschel 1955, described based on the single species Hadropus brevipennis Chevrolat 1879 from French Guiana, is herein transferred from the tribe Tanymecini, subtribe Piazomiina, to the tribe Naupactini, new placement, because it shares the typical characters of this tribe, except the presence of connate tarsal claws. Within Naupactini Aporius is probably related to Hadropus Schoenherr, 1826, based on the morphology of the rostrum, antennae, and genitalia. We redescribe and illustrate the genus Aporius and it single species, and we provide a key to separate it from Hadropus. We also discuss the taxonomic status of the remaining members of South American Piazomiina, and assign the genus Galenactus Kuschel to Leptopiini, new placement, thus removing Piazomiina from occurrence in South America.
