Features

Dorsal fin 8-9; Anal fin 32-35; Pectoral fin 12-13; Pelvic fin 9; Vertebrae total 93-95, prehaemal 49-51; prepelvic 50-53, predorsal 58-61, preanal 93-95, caudal 49-51, vertebrae between pelvic-fin origin and dorsal-fin origin 8-11.
Dorsal-fin origin relatively forward in position, predorsal length 71.8-73.6% SL; horizontal distance between origins of pelvic and dorsal fins (V-D) 52.3-63.0%; horizontal distance between origins of pelvic and anal fins (V-A); upper jaw 41.8-43.8% HL, lower jaw 55.8–62.5%.

Colour

In preservative: body blackish, densely covered with fine chromatophores; 16 saddles, consisting of very fine chromatophores, on the dorsum, those in odd numbers larger; 10 before dorsal fin; 1 at dorsal-fin base; 3 between dorsal-fin and adipose fin; 1 at adipose fin and 1 at caudal fin base, latter 2 crossing caudal peduncle. Three indistinct ventral saddles before pelvic fin, 1 at pelvic-fin base, 1 at anterior portion of anal-fin base, 1 below adipose fin and 1 at caudal-fin base, the lateral 2 connecting to the last 2 saddles on dorsum, and forming bands. Pectoral fin blackish with white base; pelvic fin with black base and white margin; dorsal fin with scattered chromatophores; adipose fin blackish; caudal fin with dense chromatophores on upper lobe and scattered ones on lower  lobe, base and middle rays whitish.  Dense chromatophores on anterior  portions of jaws, dorsal surface of head, and branchiostegal membranes; gill chamber pale. Ventral ridge on abdomen with scattered chromatophores and ventral adipose fin densely pigmented.
Colour in life unknown.

Similar Species

Differs from the similar Stemonosudis rothschildi, mainly in having 10 blotches along the back before the dorsal-fin origin (vs. 5 in S. rothschildi), and 93-95 total vertebrae (vs. 89-92). 

Etymology

The specific name is derived from the Latin multi- (= many) and fasciatus (= banded) in reference to the diagnostic character of this species having many saddles on the dorsal and ventral margins of the body.
