Abstract

Palaeozoological significance of Duslia insignis Jahn. 1893 (Arthropoda) (Incertae sedis) from the Letná Formation in vicinity of the Beroun town env. (Děd = Drabov, Ostrý and Veselá Hills) in the Bohemian Ordovician is discussed and a comparison with the evolution stadium of the taxon Psephenus herricki (DeKay, 1844) (Coleoptera) from the North American Recent is made.
