New siphonotretid brachiopod Orbaspina chlupaci is described from the Kopanina Formation (Ludlow, Silurian) of the Barrandian. Its external ornament combines pits, separated by low ridges and nodes, with a typical siphonotretid ornament of long hollow spines. Spines are restricted to edges of concentric lamellae and posterior shell margin, and indicate a schizambonine affinity. Occurrence of Silurian and Devonian siphonotretids in the Barrandian area is re-evaluated.
