I had similar issue, fixed like this. In xx/models:

from cities_light.abstract_models import (AbstractCountry, AbstractRegion,
                                          AbstractCity, AbstractSubRegion)

....            

class SubRegion(AbstractSubRegion):
    pass

connect_default_signals(SubRegion)
