The specific name honours the American zoologist Arthur Sperry Pearse, who collected the holotype. C. pearsei was first formally described as Chaetostomus pearsei in 1920 by the German-American ichthyologist Carl H. Eigenmann with its type locality given as the Castaño River at Maracay, Venezuela. This species is found in the aquarium trade where it is given the designation L187 and the name Pearse's rubbernose pleco is also sometimes used.
