Abstract

New records of the recently established genus Pampacladius, together with the confirmation that Roback and Coffman’s Genus 2 sp. is conspecific with P. gaucho, extend its range to the Austral region and South American transition zone. Specimens from Patagonia were measured and are presented in a comparative table. Intraspecific variation of P. gaucho is described and biogeographic considerations based on the new records are discussed.
