The poorly known majid genus Majella Ortmann, 1893, is revised.
The genus was previously known only from one species, M. brevipes Ortmann, 1893,
described from Japan and reported from east Africa. Majella brevipes is redescribed and
figured in detail from the type and material from the type locality,
Sagami Bay in Japan. This species is now restricted to Japan. Specimens
from east Africa are herein described as two new species: M. skolopion n. sp. and M. pristis n. sp.; they differ
markedly from M. brevipes (now restricted to Japan)
in the arrangement of spines on the carapace and pereopods, third
maxillipeds, male pleon and gonopods.
Key words: Spider crab, Majoidea, Japan,
Western Indian Ocean, Majella,
Systematics, New species.
