Abstract
The genera of the bryozoan family Chaperiidae are reconsidered on the basis of type and other material and undescribed species from the New Zealand region, and 11 genera are recognised. Uttley’s Chaperiopsis is considered to be validly separable from Chaperia sensu stricto and to include Uttley & Bullivant’s genera Scutochaperia, Parmachaperia, and Clipeochaperia (retained as a subgenus). Two new genera, Icelozoon and Exallozoon, are proposed for some species of Kluge, and Pyrichaperia n.gen. is established for a species of Canu & Bassler. Exostesia Brown, Hagenowinella Canu, and Larnacicus Norman are shown to be chaperiids, and a new genus, Bryopastor, is erected for certain Recent deep-sea and fossil species from New Zealand and the tropical Pacific. Harpecia n.gen. is established for Chaperia spinosissima Calvet and transferred to the Electridae.
