I see multiple cpus-entries with the same name. If you don't have these 16 hosts, you have a split cpid. Did you use the same email and password on all your projects?
I think you are misunderstanding what a split CPID is; the link you provided points to a host list that doesn't really tell you about a split CPID. A host list won't tell you about a CPID, since the host list only displays hosts for one user. A split CPID exists when there are multiple accounts for a user under different projects or groups of projects. The BOINCstats host list shows 16 hosts, with different configurations (processor, OS, etc) so if they have the same name it's likely because the user has given them the same name on purpose.
However, I do find two users named "papagaio" when searching the stats... One active account with the projects Malaria Control, POEM, Rosetta and SETI. Another account exists, as a member of a different team, at WCG but is not active. If you want to merge that account, you'll have to use the same account information (username, email, password) as your BAM account has. WCG has a history of being difficult with BOINC and BOINCstats, so if you try to merge them please be patient.
To the original poster: Have you checked the project's site, to make sure the credit you are missing is not in a "pending validation" status or the like? Some projects will let a bunch of work back up before validating it and giving you credit. Also, the information synched with BOINCstats is not real-time; some projects may take up to 24 hours before BOINCstats gets updated numbers.
