From the recent scientific
paper by Wright, J.J. and L.M. Page. (2006) this species is very
much like S.multipunctatus.
The diagnosis for both species is virtually identical and the main
differences concern the larger eye in S.grandiops, fewer
fin rays in the dorsal and pectoral fins, and also the much smaller
adult size. It is quite difficult to differentiate between the two
species from pictures and if you can count the fin rays (ii,7 in
S.grandiops and ii,8 in S.multipunctatus) in living
animals that is a much better bet. Dorsal spines (total): 2; Dorsal
soft rays (total): 7 - 7; Anal spines: 3 - 4; Anal soft rays: 6
- 8; Vertebrae: 34. Body is compressed laterally, with a convex
predorsal profile, interrupted by a ridge formed by dorsal rim of
eye; head somewhat depressed. Eye dorsolateral, ovoid, its diameter
64.2-81.0 % of snout length. Mandibular teeth 17-26, short and unicuspid,
arranged in a single transverse row. Maxillary barbel without basal
membrane, lacking branches or crenelations, and extending at least
to base of pectoral fin; lateral mandibular barbel extending to
point just short of anterior margin of pectoral girdle, with 4-5
non-tuberculate branches, lacking secondary branches; medial mandibular
barbel 1/2 to 2/3 length of lateral barbel, with 4-5 pairs non-tuberculate
branches, lacking secondary branches. Dorsal fin spine long, striated,
nearly straight, terminating in short, white filament; anterior
margin of fin spine with 0-3 small serrations distally; posterior
margin with small serrations distally. Pectoral fin spine roughly
equal in length to dorsal fin spine, striated, slightly curved,
terminating in short, white filament; anterior spine margin with
many small, antrorse serrations; posterior margin with large, retrorse
serrations along entire length. Adipose fin short, poorly developed,
margin convex. Body with large spots, fin spines brown to black |
