Remarks

In view of the present material, always fertile, it can be now stated that the gonothecae are sexually dimorphic, as suspected earlier by Galea (2016). Female gonothecae are longer and larger, and possess a larger number of transverse ridges, and a comparatively wider terminal funnel.

Distribution

New Caledonia ( Vervoort 1993; present study), Norfolk Ridge ( Galea 2016).
