New record of the European‑protected horned powder‑post beetle Stephanopachys substriatus (Coleoptera: Bostrichidae) in the Czech Republic after seventy years

Abstract

The horned powder post beetle Stephanopachys substriatus (Paykull, 1800) is a saproxylic beetle species listed in Annex II of the Habitat Directive and, until now, known from the Czech Republic only from historical records. This article reports the first confirmed occurrence after seventy years, from the Hostýnské hills from the Moravia region. This record is of major importance for species conservation and management planning in the area. The authors recommend including the species among the conservation targets of the Site of Community Importance Hostýnské vrchy and its monitoring. The discussion also addresses the impact of the recent bark beetle outbreak on the availability of suitable microhabitats and the need to maintain sufficient amounts of dead, declining and damaged coniferous trees. In the event of fires, the affected trees should not be removed. The optimal management aimed at conserving the species would include prescribed burning in the forests of Hostýnské vrchy and retention of fire affected trees.
