Abstract

A new genus and species of brachyuran decapod crustacean of the family Dromiidae, Quinquerugatus holthuisi, is described from the middle Eocene Tupelo Bay Formation and Santee Limestone in South Carolina. The new genus and species is morphologically similar to the dromiid Cryptodromia spp. but differs from them in having a more rounded carapace, well developed triangular rostrum, better defined grooves, and strong lateral spines.
