'''''Gitarra''''' is a genus of [trilobite](/source/trilobite) in the family [Proetidae](/source/Proetidae) that lived between the late [Tournaisian](/source/Tournaisian) and Late [Westphalian](/source/Westphalian_(stage)) of the [Carboniferous](/source/Carboniferous) period.[{{cite journal |last1=Romano |first1=M. |year=1971 |title=A new proetid trilobite from the Lower Westphalian of north-west Spain |journal=The Carboniferous of Northwest Spain |volume=2 |pages=379–383}}]
==History and classification==
The genus was described by Josef Gandl in 1968, who assigned it to the family [Phillipsiidae](/source/Phillipsiidae). This placement was challenged by Halszka Osmólska in 1970, who noted the similarity of ''Gitarra'' to the, then Proetidae, genera ''[Griffithidella](/source/Griffithidella)'' and ''[Weania](/source/Weania)''.
