Length 3.5-4.5 mm. A difficult genus including some common species; all have one large and several small spines on the underside of the front femur. The sides of the pronotum have a large pale spot just behind the middle. The critical features in S. affinis are the short wing membrane (about 3 times wider than it is long), and the antennal pattern; the 1st and 2nd segments are pale, and the 3rd and 4th segments dark (although the base of the 3rd is often pale also).
Common in leaf litter on a variety of soil, often below nettle clumps.
Adult: all year.
Fairly frequent and widespread in Britain.
Common in Leicestershire and Rutland.
