Riverside resident in provincial group (5)

Ross

I believe the answer is:

nilot

'riverside resident' is the definition.
(someone from the region around the River Nile)

'provincial group' is the wordplay.
'provincial' becomes 'NI' (short for Northern Ireland, province of the UK).
'group' becomes 'lot'.
'ni'+'lot'='NILOT'

'in' acts as a link.

(Another definition for nilot that I've seen is " One using bank's facilities".)

I've seen this clue in The Guardian.
