Abstract

Marine invertebrates, excluding decapod Crustacea, collected during the Kermadec Biodiscovery Expedition 2011 are documented. Five hundred and nine taxa, including 170 species, are recorded, principally from samples of substrate obtained from depths of less than 30 metres, although results from limited intertidal and deeper sampling are also included. The highest diversity of taxa was found at Raoul and satellite islands but this is interpreted as reflecting sampling bias. The collection reinforces previously reported patterns of faunal connectivity being strongest with the tropical and subtropical southwest Pacific. Significant discoveries to date include the recognition of approximately 20 undescribed species, 44 species distribution records that are new for New Zealand waters, an additional 25 higher level (genus or family) range extensions into New Zealand waters and 27 species distribution records that are new for the Kermadec Islands. These results indicate that there is considerable scope for further discoveries in attempts to document the diversity of the invertebrate fauna in the nearshore marine environment of the Kermadec Islands. Some recommendations are made to aid future efforts in this endeavour.
