Posterior part of body rough, covered with spine-like hairs, some small ones on the inner margin of outer maxillipeds
This stage was characterized by the lengthening of the antennules, antennas, mandibles, and maxillipeds

It was observed that differences mainly occur in the length and abundance of setea on the feeding appendages, and in the number and dimension of teeth on the mandibles and the crista dentata of the third maxillipeds
(Figure 2e): Endopod 5-segmented, distal segment ending in 1 strong distal and 2 sub-distal spines, sub-distal segment rounded distally with long serrulate setae; exopod absent.
2 = moderate movement of legs, righting time of 10-60 s in water bath, fast movement of maxillipeds
, chelae grab any object strongly and for long periods (up to 1.
Based on the third pair of maxillipeds
and on the shape of the ambulatory legs, Fenucci (1975) concluded that the two specimens were conspecific.

major described by Rodrigues (1976) show setae and spines in the endopods of the maxillules and maxillae and, numerous setae in the maxillipeds
Some species appear to have populations composed of smaller females and similar-sized males but include larger, sexually dominant males with hypertrophied weaponry (third maxillipeds
, first chelipeds, or both) (Correa et al.
In weakened crabs the chelae may close slowly, or show low resistance to manual opening Eye Touch the eye stalk with a Eye stalk retracts in the retraction blunt probe, or lift the lateral direction below the eye stalk from its carapace hood, or shows retracted position resistance to lifting Mouth If closed, attempt to open 3rd maxillipeds

with a sharp parts.
Another distinguishing characteristic is the lack of asymmetry in the setation of the exopodites of the 1st maxillipeds
of these larvae with respect of other brachyuran crabs.
