Near S. erythroptera, Boisd., but inter alia very much smaller 
and narrower, with the prothorax less strongly punctured on the 
disc, the prosternum much more closely rugulose (this may not 
be the case in both sexes), the dark colour of the suture expand- 
ing into a rounded spot considerably before the apex, and not 
continued behind the spot. Also near S. nanula, Kerremans, 
which, however, has the apex of the elytra black and rounded.
