Popis:	Three new species of the Ataphridae are described here: Ataphrus mulanguiniensis sp. nov., Chartronella paganiae sp. nov. and Chartronella spiralis sp. nov.; in addition, another doubtfully referred member of the family is recorded from the studied sections, i.e., Lewisiella? sp. The new findings here reported from the Early Jurassic of Chubut Province contribute towards the knowledge on the systematics of the family in Argentina, extending its paleogeographic distribution into the Jurassic of South America. An abundant and diverse invertebrate fauna found in association with the ataphrid genera indicates a littoral marine environment for the gastropod-bearing rocks.
