Color

The species has several possible body colour patterns: either uniformly dark (red, blackish purple, orange or brown) or dark, with either two narrow light stripes, or alternating longitudinal dark and light stripes (patterns 1, 3, and 4 of Baba, 1979), the number and width of which varies. Other colour patterns include a narrow lighter stripe in the middle of each dark stripe. Pereiopods also show variable coloration: P1 uniformly dark or with longitudinal light dorsal stripe along merus, carpus, and palm, finger tips light; some specimens with P1 uniformly dark and fingers whitish. P2–P4 uniformly dark or pale on distal portion of carpus, distal portion of propodus and entire dactylus; in some specimens, P2–P4 meri dark, and carpi, propodi, and dactyli whitish.
