Description: A small (7-10mm) long black ground beetle. Northern and upland on dry gravelly or peaty soils particularly on high peatlands.

World Distribution: A Eurosiberian Boreo-arctic Montane species (24) found across north and central Europe to north-west Siberia.

Irish Status: Widely distributed in mountainous districts of the British Isles including most of the hill areas of Ireland.

Ecology: Fairly eurytopic above 300m altitude, but most records are for summit moraine, streambanks and rocky places, rather than mire habitats.
