Huxley, 1859
The small, delicate, rounded larval nectophore is the only one developed. The bract also is small and rounded. This is a small group of species, rarely found in net material, all of which are here treated as belonging to the genus Sphaeronectes Huxley, 1859. Only one species has been found in the area under consideration.
Sphaeronectes gracilis
