Tomoxia bucephala A. Costa (Coleoptera: Mordellidae), a Palearctic tumbling flower beetle native to Europe, Asia, and northernmost Africa, is now known from North America. The first known occurrences were in 2015 in Essex and Union counties, New Jersey, U.S.A. and in 2019 in Passaic County, New Jersey, all in the New York City metropolitan area. An additional collection documents the species in 2016 from Allegheny County, Pennsylvania, in the Pittsburgh metropolitan area. The multiple occurrences, the large distance between those in New Jersey and Pennsylvania, and multiple detections in natural areas indicate T. bucephala is established in North America and apparently invasive. Several morphological features differentiate T. bucephala from the two congeners native to North America, T. inclusa LeConte and T. lineella LeConte, especially coloration patterns of elytral and pronotal vestiture, and coloration of antennae and front legs. This is the first report of a non-native mordellid species established in North America. Tomoxia bucephala does not appear to pose a significant direct economic threat in North America since it feeds in decaying trees. However, T. bucephala occurrences are within the geographic ranges of T. inclusa and T. lineella, and the biology of T. bucephala is similar to these other Tomoxia species. Thus, T. bucephala likely will expand its range within North America, with probable ecological impact on communities of native saproxylic beetles, especially T. lineella and T. inclusa.

New information is presented for Neotropical Cerambycidae (Coleoptera). Dolichestola vittipennis Breuning, 1948 is synonymized with D. annulicornis Breuning, 1942, and the species is newly recorded from the Brazilian state of São Paulo. Dolichestola densepunctata Breuning, 1942 is newly recorded from Venezuela and Brazil, and the difference between it and D. annulicornis is reported. Mecas skillmani Santos-Silva and Androw, new species, is described from Mexico (Jalisco). Pannychella callicera (Bates, 1881) is illustrated, and notes on the genus and species are provided. Pannychis Thomson, 1864 is considered a genus different from Mecas LeConte, 1852, and notes on the genus and P. sericea Thomson, 1864, new combination, are given; therefore, Mecas has no subgenera. Pannychina Gilmour, 1962 is synonymized with Dylobolus Thomson, 1868, and Pannychina atripennis (Bates, 1885) is synonymized with Dylobolus rotundicollis Thomson, 1868.

The primary types of Onciderini Thomson, 1860 (Coleoptera: Cerambycidae: Lamiinae) deposited at the Carnegie Museum of Natural History (CMNH) are catalogued and illustrated. Data on the original combination, current name, and type locality are verified and presented. There are 36 primary types of Onciderini including 12 in Oncideres Lacordaire, 1830; four in Hypsioma Audinet-Serville, 1835; three each in Hesychotypa Thomson, 1868; Cacostola Fairmaire and Germain, 1859; and Sternycha Dillon and Dillon, 1945. A brief history of the CMNH is also presented.
