Polyclads are large-bodied, free-living flatworms that occur in diverse marine habitats. They are known predators of crustaceans, ascidians, snails, bivalves, polychaetes, and other flatworms. The acotylean genus Notocomplana Faubel, 1983 currently comprises 32 species that primarily inhabit the Pacific but are also found in the Atlantic and Indian Oceans. Here, we report the discovery of Notocomplana koreana (Kato, 1937) in t...

Two conflicting morphological approaches to polyclad systematics highlight the relevance of molecular data for resolving the interrelationships of Polycladida. In the present study, phylogenetic trees were reconstructed based on a short alignment of the 28S rDNA marker gene with 118 polyclad terminals (24 new) including 100 different polyclad species from 44 genera and 22 families, as well as on a combined dataset using 18S an...
