Crozetospira dufresnei gen. n., sp. n. from Crozet Islands is laced provisionally in the Paralaeospirinae. It has asymmetrical distribution of abdominal uncini, 3 thoracic setigers and simple collar chaetae with coarsely serrated and cross-striated blades. Paralaeospira pseudotenuis sp. n. from Heard Island differs from other Paraleospira in having a strongly calcified conical opercular 'plate' without a talon. Romanchella sepicula sp. n. from Crozet and Marion Islands is unusual for the genus in having a pin-shaped talon. Brief descriptions of what appear to be a Eulaeospira sp. and a Nidificaria sp. (from Adelie Land and Kerguelen Islands respectively) are based on non-brooding specimens. The former has unusual opercular morphology, with two talons on the same opercular plate.
