Jim,
Thank you! I encountered the word Rassenkreis many years ago, used to
describe exactly the situation David mentions. The example given was a
moth, I think, with one end of the arc in Florida in the US, and the
other end somewhere around Belize.
But I somehow got a bad spelling of Rassenkreis in my head, and despite
only being a couple of letters off was never able to get a hit on it -
until now. A long-standing irritation resolved, just in time for
Christmas!
