ABSTRACT
Retrotapes, new genus, comprises a group of Neoaustral bivalves
that appeared in the southern circumpolar regions by
the Eocene and have since been confined to the high latitudes
of the southern hemisphere. Its presence in the Tertiary strata
of Antárctica and southern South America reflects an active
faunal interchange between both regions during the Eocene.new genus, comprises a group of Neoaustral bivalves

Retrotapes is here proposed to include to those Recent and
Tertiary representatives of the Subfamily Tapetinae (Family
Veneridae) from southern South America and Antárctica that
had been previously placed in Venus Linné, 1758, Marcia H.
