Description: Although less conspicuous, this species differs by having: dark spots scattered throughout the dorsolateral surface (vs. spots restricted to saddles in S. boa, S. cervigoni, S. haeckelii); anterior nasal flaps covering the upper lip (vs. flaps not reaching upper lip in other species, except S. canicula, S. cervigoni, S. comoroensis, S. garmani, S. stellaris); interdorsal distance 0.6-1.0 times anal base (vs. greater than the anal base in S. boa, S. cabofriensis, S. haeckelii, S. hesperius, S. meadi, S. retifer, S. torrei, S. ugoi); mandibular canal of lateral line system with 4 or 5 pores (vs. 6-7 in S. stellaris); oral canal of lateral line system with 10-12 (vs. < 10 pores in the other species, except S. torrei); commissural teeth with two cusplets (vs. one in S. cervigoni, S. torazame and S. torrei; four or more in S. boa, S. canicula, S. hesperius); pelvic apron extending almost the entire length of pelvic inner margins (vs. extending to 2/3 of length in other species, except in iS. capensis, S. canicula, S. torazame, S. torrei); clasper with smooth terminal dermal cover (vs. rough in S. canicula, S. capensis); terminal 3 cartilage absent (vs. present in S. boa, S. canicula, S. capensis, S. retifer, S. torazame); dorsal terminal 2 cartilage elongated and 1/4 length of dorsal terminal cartilage (vs. reduced and subtriangular in iS. cabofriensis, S. capensis, S. cervigoni, S. haeckelii, S. ugoi; 1/3 of dorsal terminal cartilage in S. boa, S. comoroensis; both cartilages the same length in S. torazame); counts of monospondylous vertebrae 35-37 (vs. 44-46 in S. capensis; 40-45 in S. cervigoni; 48 in S. garmani; 46-48 in S. meadi; 43-47 in S. stellaris; 32-35 in S. torrei); upper tooth rows 41-45 (vs. 45-58 in S. cabofriensis; 46-76 in S. capensis; 48-54 in S. haeckelii; 46-54 in S. meadi; 47-56 in S. ugoi); lower tooth rows 39-42 (vs. 44-50 in S. cabofriensis; 43-53 in S. haeckelii; 43-49 in S. meadi; 43-53 in S. ugoi); adult males at least 340 mm TL (vs. adult males greater than 450 mm TL in S. capensis, S. cervigoni, S. meadi, S. stellaris, S. ugoi; adult male 269 mm TL in S. torrei) (Ref. 120402).
