Answer
Jose Luis Solis Lopez is frequently omitted as Subcomandante Insurgente Galeano because he was not the only one to hold the position. Subcomandante Insurgente Galeano was a pseudonym used by several Zapatista Army of National Liberation (EZLN) leaders, including Jose Luis Solis Lopez. Solis Lopez was the first to use the pseudonym, and he held the position from 1994 to 2003.
