Sertularella bipectinata Vervoort, 1993: 207, figs 43c–e, 44.

Material examined

BATHUS 3: Stn. DW809: a 2.2 cm high, sterile, lightly fascicled (a couple of accessory tubes) stem, provided with two short side branches (MNHN-IK-2012-16580).

1993, and S. leiocarpoides Vervoort, 1993, and comparisons with their respective holotypes (second

column for each species).

Remarks

The present material, although similar to that assigned above to S. aff. anguina Vervoort, 1993, differs from it through its comparatively thicker internodes, a more reduced ratio of internode length/hydrothecal depth, and the comparatively larger size of its hydrothecae (Table 5). These features, in combination with the presence of three internal, submarginal cusps (two latero-adaxial and one abaxial), also reported by Vervoort (1993), suggest that it may belong to S. bipectinata, and this identification should be regarded as provisional in the absence of fertile material.

Geographical distribution

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