Distribution Patterns of Argestidae Por, 1986 (Copepoda Harpacticoida) in the South Atlantic Ocean – first results from DIVA 2
Argestidae Por, 1986 are one of the most abundant taxa in the muddy sediments of the deep oceans. This family with up to date 20 genera and 83 described species shows well visible diagnostic characters allowing quick identification at least to family level. In most of the cases, the Argestidae found...
