The Klarshameth were a group that existed within Vulcan society which lived by the 23rd century.

They were a traditional troupe of performers who were swift, cat-like along with being quite muscular for their role as professional atheletes. In 2283, they were touring the city of T'lingShar which allowed a group of Romulans to infiltrate the planet Vulcan and kidnap several of the Warrantors of Peace. (TOS novel: Dwellers in the Crucible)
