Reading through the Corpus Aristotelicum we come across a group of expressions meant to indicate predicative relations, which lead us to think that Aristotle connected predication to a part-whole relation. He frequently calls the ‘εἴδη’, “species”, ‘μέρη’, “parts”, of their genera. More generally, the universal is said to contain that of which it is true. In a parallel way, what is contained by something is also what is under something else. Again, it is quite common for him to consider the (...) species as partaking of their genera. Although the relation of partaking is normally used to qualify the way in which species are related to their genera, sometimes also the relation between particulars and species or even genera is expressed in terms of partaking.

First of all, Aristotle does not seem to be committed to hold that there are different types of identity, The second point concerns contingent identíty. What Aristotle says about numerical identity does not commit him to the view that identity can be contingent and it is consistent with the (...) claim that identity statements are in all cases necessary.
