Abstract 

A review of the osteology of the tristichopterid sarcopterygian Eusthenopteron kurshi Zupinš, 2008, from the Lower Frasnian of Latvia, indicates that it should be placed in the genus Tristichopterus, and a new combination Tristichopterus kurshi Zupiņs is proposed. The features that support this include: the number of coronoid fangs, proportions of the coronoids and the skull roof, and the relatively small epichordal lobe of the caudal fin. Recognition of a second species of Tristichopterus extends the stratigraphic range of the genus to the Upper Devonian, and its geographic range to the Baltic Region in northern Europe.
