Carapace narrow (breadth about 1.5 times length); surface with close-packed granular areas with a fine pubescence among the granules; regions well recognizable on denuded specimens; front with 2 broad, reasonably sharp lateral lobes, and a central confluent lobular area without clear lobes; antero-lateral borders with 9 teeth, last one slightly most protruding; postero-lateral junction rounded. Antero-external angle of merus of third maxillipeds markedly produced into a lobe.
