Pincers dissimilar, ridged longitudinally, fingers compressed but broadened dorsoventrally producing pointed spatulate shape; fifth legs flattened in form fifth legs flattened in form of paddles. Male with T-shaped abdomen reaching slightly beyond suture between thoracic sternites 4 and 5, sixth segment nearly parallel-sided but broadened proximally; first pleopods short, reaching about midlength of sternite 7, approximately each other or occasionally overlapping at level of abrupt curve beyond which short terminal part tapers to rather sharp tip; armed with minute scattered retrogressive spinules distally.
