L. gibbosa A. Milne-Edwards, 1878 Libinia ferreirae is a species of tropical spider crab in the family Epialtidae.

Like other spider crabs, Libinia ferreirae has a roughly circular spiny carapace that extends forwards into a rostrum between the two, stalked eyes.

[2] Libinia ferreirae is found off the Atlantic coast of South America in the intertidal zone and at depths down to about 35 metres (115 ft).

The carapace of the zoea has one short rostral and one curved dorsal spine and some of the abdominal segments have spiny projections.

Juvenile crabs are found living within the bell, on the oral arms or clinging to the exterior, even on jellies that have been stranded on the shore.
