Organs of Pesta present. The coloration of this "half red" species was observed in the fresh state as follows. Red stellate chromatophores were scattered all over body and appendages, but with a greater concentration on the carapace. The posterior half of the dorsal surface of the carapace had a distinct purplish-blue cuticular pigment present, and another small patch of the same pigment occurred laterally on the carapace in the area of the anterior organ of Pesta. The stomach is clearly visible through the carapace as a large greenish-black anterodorsal mass.
