TL;DRAbstract

A new genus and species, Dumosus atari of the Maera group from coral rubble at Belize is described. It is related to Gammarella and is probably cryptic. The eyes are reduced. Dumosus differs from Gammarella in the loss of medial setation on the maxillae, reduction of article 3 on the mandibular palp, loss of article 2 on the outer ramus of uropod 3, and in the loss of major spination on the plates of maxilla | and the maxilliped; in contrast to Gammarella, Dumosus retains the plesiomorphic uropod 3 typical of the Maera-group.
