Understanding the diversity and spatial distribution of benthic species is fundamental to properly
assess the impact of deep sea mining. Tanaidacea provide an exceptional opportunity for assessing
spatial patterns in the deep-sea, given their low mobility and limited dispersal potential. The diversity
and distribution of pseudotanaid species is characterized here for the Clarion and Clipperton Fractures
Zone (CCZ), which is the most extensive deposit field of metallic nodules. Samples were taken from the
Belgian, German and French license areas, but also from the APEI 3 (Area of Particular Environmental
Interest 3) of the Interoceanmetal consortium associates. The combination of morphological and
genetic data uncovered one new pseudotanaid genus (Beksitanais n. gen.) and 14 new species of
Pseudotanais (2 of them virtual taxa). Moreover, our results suggest that spatial structuring of
pseudotanaid diversity is correlated with deep-sea features, particularly the presence of fractures
and seamount chains crossing the CC Z. The presence of geographical barriers delimiting species
distributions has important implications for the establishment of protected areas, and the APEI3
protected area contains only one third of the total pseudotanaid species in CC Z. The specimen collection
studied here is extremely valuable and represents an important first step in characterizing the diversity
and distribution of pseudotanaids within the Tropical Eastern Pacific.
