You have to be more precise about the time period. Karl Marx was the original leader of the Communist party. That is why it is sometimes called Marxism. Lenin led the Communist Party at the time of the Russian Revolution, Russian Civil War, and into the 1920s. Stalin, Kruschev, and Breshnev all led the Communist Party at various times.
Vladimir Lenin was the first communist leader for Russia. After the successful revolution against the Russian Provisional government in October, 1917, Lenin later discarded the term Bolshevik in favor of Communist. The party soon after changed the name of Russia to the Soviet Union.
Russian Communist Workers Party was created in 1991.
Vladimir Lenin was the leader of the radical faction of the Russian Socialist Democratic Labor Party known as the Bolshevik Party. In March 1918, they changed their name to the Communist Party.
The Communist Party, as known today, emerged from the split within the Socialist movement in 1917, led by Bolshevik leader Vladimir Lenin in Russia. The party gained prominence during the Russian Revolution and eventually became known as the Communist Party of the Soviet Union.
Communist Party of the Russian Federation was created on 1993-02-14.
Before the Russian Revoultion they were called the Bolsheviks and after it was the Communist party of the Soviet Union. Today the main communist party is the Communist party of the Russian Federation which today is one of the largest political parties in the Russian Diet (Paraliment)
There are three possible answers to this question because there were (at least) three political parties that could be deemed "socialist revolutionaries. First is the Bolshevik Party. Vladimir Lenin was the chief leader. Second is the Menshevik faction of the Russian Social Democratic Labor Party. Julius Martov was the chief leader of that party. Third is the Party of the Socialist Revolutionaries. Victor Chernov was the chief leader of that party. Most likely this question refers to the Bolshevik Party under Vladimir Lenin, since it is the political party which overthrew the Russian Provisional Government (not the Tsar) in the October Revolution and later became the Communist Party.

The Bolshevik Party (later renamed the Communist Party) led the Russian Revolution of October 1917. The previous revolution in that year, the February Revolution, was not ed by any particular political party.
Communist Party of the Russian Soviet Federative Socialist Republic ended in 1991.
The Russian Social Democratic Labor Party (RSDLP), a Marxist political party, wanted a Communist state. The RSDLP had two factions, the Bolshevik and the Menshevik factions. The Bolsheviks eventually split from the RSDLP, took control of the Russian Provisional Government and created the first Communist government. At first the new communist nation was called the Russian Soviet Federated Socialist Republic and then became the Union of Soviet Socialist Republics, the USSR or Soviet Union.
