T. dorsatus has also been reported from Wyoming and South Dakota, however, there may still be some confusion regarding the details in range distributions between dorsatus and tremulus - coupled with erroneous id's incl. T. dealbatus with which it is sympatric across much of its range and occasionally confused.
