“So the sons of Israel gave to the Levites the cities and their pastures. And they gave by the lot, out of the tribe of the sons of Judah, and out of the tribe of the sons of Simeon, and out of the tribe of the sons of Benjamin, those cities which are called by names;” named, that is, in the list of 1 Chronicles 6:55-60, above. This is clearly a summing up of the whole account so far. The eleven tribes have all been mentioned in 1 Chronicles 6:61-65.
The “cities” of 1 Chronicles 6:64 are those included in 1 Chronicles 6:61-63. So the parallel verse (Joshua 21:8) refers back to Joshua 21:5-7, which is parallel to our 1 Chronicles 6:61-63. Joshua 21:9 (=our 1 Chronicles 6:65) introduces the names of the cities which fell to the Aaronites. But there is no real divergence between that account and this; because 1 Chronicles 6:65 also refers back to the list of the same cities in 1 Chronicles 6:55-60. The chronicler adds Benjamin, with reference to 1 Chronicles 6:60, to make his tribal list complete.
