If I were to guess I'd say it's the S. hermosa, as described in "ON A COLLECTION OF MILLIPEDES AND CENTIPEDES FROM NORTHWESTERN PERU, Ralph V. Chamberlain, 1941":
Dorsum dark olive with the first dorsal plate, prehensors and the head nearly chestnut-brown. Antennae olive. Legs proximally brown.
Antennae short, composed of 17 articles of which the first four are glabrous.
Hope I'm right on this one, but the best you can do is wait for Steven
