Quedius fuliginosus -group

Diagnosis. Head with 4 or 6 interocular punctures between anterior frontal punctures. Generally largest species within the subgenus with entire body dark; only rarely elytra reddish. Temporal puncture situated at posterior margin of eye. Paramere does not extend over median lobe apex, peg setae arranged in single rows; median lobe without large teeth on parameral side, at most with small teeth or subapical notch; internal sac without large c-shaped sclerite. Generally widespread species, common in the Palearctic region, found in diverse ground-based debris in both forest and open landscapes. Only Quedius afrofuliginosus is rare, possibly an artefact of both misidentifications and poor sampling in parts of its range.
