Synonyms and other taxonomic changes
up-to-date taxonomy in (1)
most of the families included here (Artheneidae, Blissidae, Cymidae, Geocoridae, Heterogastridae, Ninidae, Oxycarenidae, Pachygronthidae, Rhyparochromidae, and 3 minor exotic families) used to be treated as subfamilies of Lygaeidae
ca. 340 spp. in >100 genera of 12 families in our area, ~4,300 spp. in >700 genera of 15 families worldwide(1)(2); the vast majority of families are still treated sometimes as parts of Lygaeidae(3)(4)
best illustrated keys to most NA genera in (3); keys to Prairie Province spp. in (5)
Rostrum with 4 segments. Tarsi with 3 segments. Hemelytral membrane with 4 or 5 simple veins arising from base. Ocelli usually present.
Mostly seed- and sap-feeders; a few are predators(2)
