Unique find of a porambonitid brachiopod in the Šárka Formation (Darriwilian) in the Prague Basin, the Czech Republic, is described. Porambonites havliceki sp. nov. is characterized by thin shell with finely pitted radial multicostellate ornament, long parallel brachiophore plates and long dental plates. It is the earliest known representative of the family Porambonitidae in the West Gondwana. Poramborthis, an orthid-like syntrophiid genus abundant in the Tremadocian of the West Gondwana, is assumed the evolutionary ancestor of the Porambonites. Pitted multicostellate ornament is suggested synapomorphy of the porambonitid brachiopods.
