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).
