Abstract

The species Gravatamberus pilosus Mendes & Andersen, 2008 is recorded for the first time in Argentina. The species is known from Chile and this new record should be taken as documentation of the occurrence of G. pilosus in the Eastern side of the Andes. As adult males showed differences from the original description, a description of the Argentine specimens is provided to describe their intraspecific variation. Female adults belonging to the genus Gravatamberus were collected in the same locality and are interpreted as the female of G. pilosus. Therefore, a detailed description of the female for the genus is provided for the first time.
