New genus and species of Calanticidae (Cirripedia, Thoracica, Scalpellomorpha) from Australian waters

A previously undescribed calanticid species was found in the collections of the Australian Museum, Sydney. The combination of features match some of the characteristics of the genus Smilium, as currently defined, and do not fulfil the necessary criteria for inclusion in any of the remaining calanticid genera. Several characters, however, are typical of Calantica. Therefore, a new genus and species is proposed and is accordingly named Crosnieriella acanthosubcarinae. The uncertain relationships between the presently recognised calanticid genera are discussed.
