Contribution to the knowledge of the proseriata (platyhelminthes, seriata) from eastern Australia: Genera necia marcus, 1950 and pseudomonocelis meixner, 1938 (partim)

Abstract

Two monocelidid species from eastern Australia are described. Necia boreoceloides n. sp. is characterized by an extremely elongated, adhesive tail, and further distinguished from the only known congeneric species by details of the reproductive system. A Gondwanian origin of the genus Necia is proposed. Pseudomonocelis hoplites n. sp. differs from congeneric species by the presence of an accessory organ provided with a stylet. The definition of the genus Pseudomonocelis is accordingly modified.
