From Brown, 1953 
Worker: I refer to this species three specimens from Cadenabbia, Como, Lombardia (G. Binaghi) in the Finzi Collection. The clypeal hairs are decidedly more slender and elongate than those of baudueri, distinctly raised in an arch away from the surface of the clypeal) disc and curving anteriorly and mesially. The apices of the hairs are seen to be narrowly spatulate at magnifications of 60X and more. The hairs of the remainder of the cephalic dorsum are longer and more filiform than those of baudueri. Emery's origi¬nal description is as follows in translation:
"... differing from all the other examples of baudueri I have seen in that the clypeal hairs are not squamosely dilated, and for this reason do not appear as white points." I have already noted his comparison to S. pilinasis in the discussion above. The size, pro¬portions and other characteristics as in baudueri.
