Revision of family and some generic definitions in the Phaennidae and Scolecithricidae (Copepoda: Calanoida)

Abstract Some genera have been removed from the family Phaennidae which, with the Scolecithricidae, are redefined. All other genera have been placed close to the Diaixidae and Tharybidae. The scolecithricid genera Scolecithrix, Scolecithricella, Amallothrix, Scaphocalanus and Lophothrix are redefined. It is suggested that the species Scolecithrix ctenopus, S. auropecten, S. fowled and Amallophora altera represent four groups of species which probably should be given generic status. A new species of Parundinella is named and a juvenile Neoscolecithrix described.
