Looks like the 'extra' arm is a mutation growing about 1/5 of the way up Arm IVR. As Mori said, this could be the result of a regenration/healing site gone awry - I reported a specimen of Onykia (Onykia) robusta in my thesis that also looked like a tiny mutant arm was sprouting from a damaged sucker site (see below - scale bar = 10mm).
