Specimens of Anthocoridae, Lyctocoridae, and Lasiochilidae (Hemiptera: Heteroptera) intercepted at various ports-of-entry and housed at the Animal and Plant Health Inspection Services (APHIS) Miami Plant Inspection Station (Miami, FL) were examined and identified to species or genus. The collection comprised 127 specimens intercepted primarily at the Miami Inspection Station. Specimens were distributed among 14 genera and 26 identified species in 3 families: Anthocoridae (99 specimens), Lyctocoridae (9 specimens), and Lasiochilidae (19 specimens). Seventy-eight of the 127 specimens could be identified to species. The remaining 49 specimens were identified to genus, except for 2 specimens that could not be identified below tribal level. For each identified species, we provide brief descriptions of habitat and prey preferences (where known), and a summary of currently known geographic range. Fifty-six of the 127 specimens were of a single genus: Orius Wolff, 1811 (Anthocoridae: Oriini). The specimens of Orius comprised at least 9 different species; 17 specimens could not be identified to species. The 127 specimens were intercepted on a variety of commodities, including ornamental plants, cut flowers, bouquets, agricultural produce, ceramic tiles, and wood products. Fourteen of the identified species do not currently occur in the continental U.S.; moreover, the 49 specimens that we could identify only to genus very likely also are of species not currently established in the continental U.S. The majority of intercepted specimens (93 of 127) arrived on shipments from the Neotropics and Europe. Specimens of Lasiochilidae and Scolopini (Anthocoridae) were entirely from shipments arriving from the Neotropical region. Specimens of Orius were intercepted on shipments from the Neotropics, Mexico, Europe, and Sub-Saharan Africa. Finally, 10 species were intercepted on shipments arriving from countries not previously listed as being part of their known geographic ranges. One Old World species, Cardiastethus affinis Poppius, 1909, known previously only from East Africa and India, was intercepted in 2 separate shipments arriving from Central America and the West Indies.
