While only 4 species were known for the family Nannastacidae in West Africa, a recent study has revealed 11 more species - Procampylaspis maurini, P. arguini, P.thalassae, Cumella africana, Schizotrema atlantica, Campylaspis macrophthalma, C. mauritanica, C. bonetti, C. legendrei africana, C. jonesi. Of these, S. atlantica and the last 4 Campylaspis species are new species, and are described. Both male and female adults are described, with explanatory diagrams, and additional observations are included. The species of Campylaspis are incorporated modified form. It is thought that this description completes not only acquaintance with the fauna of the Saharian section of the Atlantic, but also the whole of the Atlantic Ocean. |
