Remarks
Like all Nymphon but one found in Madibenthos material (i.e., Nymphon timons sp. nov.), this species is part of the aequidigitatum group as defined by Child (1988b) and for which Takahashi et al. (2012) provided a complete identification key. Species of this group share the following five characters: (i) a long fifth palp article relative to the other four; (ii) an oviger claw without denticulation, and most often (iii) bifurcate chela teeth, (iv) propodus main claw as long as or shorter than auxiliaries, and (v) one or all propodal claws bearing endal rugosities or setules.
This is the first record of this species for Martinique. It was only collected on the Atlantic coast, where it was found to be rather common.
Distribution
Tropical West Atlantic (Gulf of Mexico, Caribbean, Surinam).
Depth range
0.5– 37 m.
