Sycortis sycilloides Schuffner, 1877

This Mauritius species is discussed above as a possible junior synonym of Sycettusa stauridia (Haeckel, 1872) . It has similar habitus (two coalescent small tubular individuals), but it has the unpaired actines of the subatrial triactines much longer and thicker (600– 1000 x 80 µm) than Haeckel’s and ours, which measure only 400 x 10–20 µm.
