| G. A. Bishop 1988 | Carapace pentagonal, twice as wide as long, well differentiated by
grooves into smooth, plateau-like areolations. Rostrum very narrow, downtumed, not grooved, rounded at tip. Anterolateral margin with two small orbital spines plus large spine at widest point Vy distance from front. Orbits large, eyestalk long and slender. Posterolateral margins straight and steep. Posterior margin slightly concave. Areolations on carapace raised into plateaus, small transverse ridge on protogastric region even with distal ends of cervical groove. Anterior portion of epibranchial lobe developed as a narrow, distal ridge behind cervical groove. Cardiac region bilobed, decreasing in relief posteriorly until merging with intestinal region. Chelipeds long, arched upward, keeled and slightly heterochelous. Walking legs long, P. oval, P3-P5 flattened, P5 smallest with straight dactylus. |
