New localities of Elmidae (Coleoptera: Byrrhoidea), with a revised checklist of species occurring in Poland

Abstract

Seventeen species of elmid beetles have been unequivocally recorded from Poland. The paper presents new data on the distribution of 13 species of this family, among which Esolus parallelepipedus and Riolus cupreus have been proved to occur in the country. Altogether 227 localities are given, either from the authors' own observations or from materials gathered during the implementation of the programme "Monitoring of the ecological state of surface waters, studies and an assessment of the ecological state of rivers" coordinated by the Chief Inspectorate for Environmental Protection in Poland. The paper also includes a revised checklist of Elmidae occurring in Poland.
