B) the apophysis on fixed finger is small and triangular, but as the male grows it develops into a large and robust projection. Also, as the male grows, the apophysis rotates, turning almost parallel to the ventral margin of the propodus in the largest male. The tooth on the ventrodistal angle of the propodus is here referred to as “robust tooth”. The area between the robust tooth and the apophysis decreases in size as the male grows, being reduced to a small unevenness on the ventral margin of the propodus in the largest males. In contrast, the U-shaped notch is poorly developed in the juvenile male, but became wider and deeper as the specimen become larger. A detailed description of this ontogenetic process of the male cheliped is reported below:

E). As the previous form except for: propodus huge, 2.6 times carpus length. Fixed finger, robust tooth blunt; apophysis roughly slanted 10º–16º upwards about propodus ventral margin, i.e., it becomes almost parallel to propodus ventral margin. Area between robust tooth and apophysis vestigial. U-shaped notch much wider, approximately 2.9 (2.3–2.6) times broader than fixed finger. Dactylus claw blunt. Note: in other specimens examined, the robust tooth, the apophysis and the claw are sharper than in the specimen drawn.
