NEWLY RECOGNIZED HOLARCTIC AND INTRODUCED PLANT BUGS IN NORTH-AMERICA(HETEROPTERA, MIRIDAE)

The first North American records for Deraeocoris punctulatus (Fallen), Labopidea artemisiae (Sahlberg), and Labopidea bermani Kerzhner indic ate that the species are naturally Holarctic. Lygus rugulipennis Poppi us is now considered naturally Holarctic after specimens of Lygus perp lexus Stanger from Alaska, Yukon Territory, and Northwest Territories are correctly identified as L. rugulipennis. Additional North American localities for Labopidea discolor (Sahlberg) support the contention t hat the species is naturally Holarctic. Collections of Orthotylus ochr otrichus Fieber from Royal Oak, British Columbia, and Malacocoris chlo rizans Panzer from British Columbia and Washington state suggest that these species are adventive to North America. Diagnoses are provided t o distinguish all the taxa from other North American congeners. A key to the northern Nearctic species of Labopidea is given.
