Abstract

Two species of the genus Callograptus Hall, 1865 with strikingly lateral branching of some stipes are described from the Klabava Formation (Lower Ordovician of Bohemia). On the basis of new material the original description of the species Callograptus holubi Bouček, 1956 is completed and Callograptus ludmilae sp. n. is established.
