Blaps is a cosmopolitan genus of darkling beetles with attenuated ends to the elytra. Species are native to Eurasia and Africa but B. polychresta has been introduced to North America and Australia. In Australia, this species feeds on spilled grain and rabbit faecal pellets (Matthews & Bouchard 2008).

Characters (from Matthews & Bouchard 2008): Surfaces matt black. Head in repose porrect. Anterior margin of labrum emarginate, its fringe interrupted medially. Clypeolabral membrane narrowly exposed across its entire width. Mesocoxal cavities open. Elytra completely covering abdomen, apices prolonged and tapering.
