Remarks. There are currently two species in this genus, S. planirostrum Richer de Forges & Ng, 2009, from New Caledonia, and S. pteridion Lee, Richer de Forges & Ng, 2017, from the South China Sea. As discussed by Richer de Forges & Ng (2009b), this genus is distinct from Oxypleurodon Miers, 1885, and Sphenocarcinus A. Milne- Edwards, 1875, by having a fused, roof-like carapace plate instead of distinct smaller plates on each region of the carapace.
