discussion
Remarks The four available specimens were compared to a colony of Sertularella leiocarpa (Allman, 1888) from Inaccessible Island (see Galea 2015 b). Portions of three of them are illustrated altogether with S. leiocarpa, so as to show their specific differences (compare Fig. 5 D – F and 5 G). As already noted by Vervoort (1993), the internodes are thick, short and geniculate in S. leiocarpoides, and comparatively more slender, longer, and less geniculate in S. leiocarpa. In addition, the hydrothecae of Vervoort’s species have the adaxial cusps characteristically upturned, and there are generally also two inconspicuous latero-adaxial, internal, submarginal projections of the perisarc and, occasionally, a third one, on the abaxial side. Geographical distribution New Caledonia (Vervoort 1993; present study), Solomon Islands (present study).
