Summary:The phylum Nematoda Cobb, 1932, also known as roundworms, is the most abundant metazoan taxon in aquatic sediments worldwide, as well as one of the most diverse. Despite their ubiquitous distribution, our knowledge of nematode taxonomy and diversity in Aotearoa New Zealand, and in particular, free-living species in marine sediments, remains very limited. The nematode fauna of New Zealand’s marine environments, ranging from the most accessible beaches to abyssal plains, remains poorly known, with the total biodiversity of the free-living marine nematode fauna in the New Zealand Exclusive Economic Zone estimated at several thousand species. Prior to this work, the total number of free-living marine nematode species known from the New Zealand region was 190 species. Unlike previous recent NIWA Biodiversity Memoirs which focus on a particular taxon group rather than a specific region, this work focuses on the nematode fauna of Pāuatahanui Inlet, a drowned river valley and one of two arms of Te Awarua-o-Porirua Harbour in the Wellington region. The main reason for this regional approach is that the New Zealand marine nematode fauna remains largely uninvestigated, and very few specimen collections are available. The most efficient way to increase our knowledge of free-living marine nematode taxonomy in New Zealand is therefore to begin describing the fauna from an easily accessible environment. Pāuatahanui Inlet was chosen because, while it has high ecological and cultural significance, it is also subject to anthropogenic impacts associated with changes in surrounding land use and pollution. A better knowledge of the nematode fauna will thus bring a more complete understanding of the ecological value of this ecosystem and should facilitate ecological monitoring in the future.
