This stage was characterized by the lengthening of the antennules, antennas, mandibles, and maxillipeds (Fig.

Second Maxilliped (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.

Based on the third pair of maxillipeds and on the shape of the ambulatory legs, Fenucci (1975) concluded that the two specimens were conspecific.

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 retract to closure (extend) the 3rd cover the smaller mouth 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.
