| Diagnose | Carapace more than twice as broad as long; 9 blunt to acuminate teeth (outer orbital tooth and strong lateral spine included) on arched anterolateral margin; front (excluding inner orbital angles) bearing 2 obtuse to acuminate, broadly triangular teeth with often sinuous inner margins longer than outer margins. Much of convex dorsal surface smooth, but scattered and transverse lines of fine granules; sculpture of regions near center varying from low and smooth to rather sharply raised relief with crowded granules; pincers strong, dissimilar, and ridged longitudinally; fifth legs flattened in form of paddles. Males with T-shaped abdomen level of thoracic sternite 4; slender first pleopods with membranous tip reaching beyond suture between thoracic sternites 4 and 5; sinuously curved overlapping proximally and armed distally with a row of large and small retrogressive spinules. Color: greyish, bluish, or brownish green. Males with propodi of chelae blue on inner and white on outer surfaces, fingers blue on inner and white on outer surfaces and tipped with red. Mature females with orange fingers on chelae tipped with purple. Underparts off-white with tints of yellow and pink. Color variations is associated with sexual dimorphism and molt cycle. |
