Length 2.5 to 3.5 mm.  Stygnocoris species are small ground bugs in which the pronotum and forewings are covered in fine hairs. The pronotum is punctured throughout, and the front femora lack spines. Stygnocoris fuligineus and the closely related Stygnocoris sabulosus are very similar; this species is distinguished by the duller aspect of the dorsal surface, the much shorter pubescence and the darker femora. It is always macropterous. 

Detailed examination of the specimen is needed to identify the species (a photograph alone is not normally sufficient because key features are too small or hidden).

Unless identified by a recognised expert, a photo is required. If the photo doesn't show the key ID features then in the comments box describe the size and identifying characters you have observed.

Found in a variety of grassy habitats.

Adult: All year. There are probably two generations a year which mature in the summer and autumn.

Widespread in Britain.

Status in Leicestershire and Rutland not known.
