General Description

Rostrum reaching slightly beyond, but not far exceeding tip of scaphocerite, broad and straight; with 7-8 dorsal teeth, 2-3 ventral teeth. Flagella of antennule fused for 6-7 articles (one-fifth of length). Fifth segment (carpus) of second leg (pereopod 2) shorter than palm (propodus proximal to finger), not reaching tip of scaphocerite. Saddle stripes of red across back and sides of whole body; less distinct on carapace; palm of pereopod 2 with narrow red band; fingers with similar band half way along. Up to 1.5 cm long.
