Typical for Scyllarides, with extremely hard carapace and abdomen which are thickly and uniformly covered with round appressed, rather scaly granules. Carapace quadrilateral, its length being slightly more than width; a shallow constriction at hepatic margin, and seven small teeth in front of it, and about 12 behind it. Antenna flattened as usual; anterolateral margin of second segment tuberculated, and two teeth each on inner and outer margins. Abdomen also somewhat scaly on its dorsal surface, without distinct median ridge or hump; three dark spots on first segment.
Distribution:
Off Guyana and Suriname, 31-80 m deep.
Remarks:
In a close congener, the ridged slipper lobster S. nodifer (Stimpson) which ranges from North Carolina to the Gulf of Mexico, there are median ridges on the abdominal segments, and another congener with a wide distributional range from the Gulf of Mexico to Brazil, the Spanish slipper lobster S. aequinoctialis (Lund) is readily distinguished from this species by the presence of four spots on the first abdominal segment.
