Most of the information about this fauna comes from sporadic
collections and is scattered among the taxonomic literature. Perhaps
the only systematic surveys of the decapod fauna in areas included
in the Guayana Shield region are the inventories made by Lópes &
Pereira (1996, 1998), for the Orinoco Delta, and by Magalhães &
Pereira (2003), for the middle Caura River Basin.
