This species was not intercepted at U. S. ports-of-entry between 1995 and 2012, but it had been intercepted at least 5 times before that. We have examined specimens taken in quarantine from Japan (Pinus). It occurs on several species of pine in the Palaearctic zoogeographic region; it also has been introduced into the Nearctic area, where it has been recorded as M. resinosae, which is synonym of M. matusumurae. No other species of Matsucoccus have been taken in quarantine at U.S. ports-of-entry.
