In the new Tyranid Codex (6th Edition) is the Close Combat Weapons bonus included in Unit profiles?
It used to be that this was reflected by the use of parentheses, e.g. 3(4)

This forum post talks about this(although not in relation to the models you mentioned). The consensus seems to be that if it is not explicitly stated that it is factored into the profile, then it's in addition to the profile.
