Ctenicera Latreille, 1829 in North America has historically been overly broad in concept, differing from European authors who recognized multiple genera. Recent efforts have been taken to align generic concepts in North America and Eurasia. Two genera were recently described for North American species formerly in Ctenicera that require comment: Billbrownia Johnson, 2023 and Tesolasomus Johnson, 2021. These genera are here synonymized with other genera: Billbrownia is synonymized with Neopristilophus Buysson, 1894, new synonym, and Tesolasomus is synonymized with Pristilophus Latreille, 1834, new synonym, using characters of external morphology, male and female genitalia, and larvae when available. These synonymies create a total of 14 new combinations, seven in each genus: Neopristilophus coniungens (LeConte, 1853), new combination, Neopristilophus copei (Horn, 1871), new combination, Neopristilophus lecontei (Candèze, 1881), new combination, Neopristilophus obversus (Horn, 1871), new combination, Neopristilophus praeses (Horn, 1871), new combination, Neopristilophus rupestris (Germar, 1843), new combination, Neopristilophus signaticollis (Melsheimer, 1846), new combination, Pristilophus blanditus (Brown, 1936), new combination, Pristilophus castanicolor (Fall, 1934), new combination, Pristilophus deceptor (Brown, 1936), new combination, Pristilophus funereus (Brown, 1936), new combination, Pristilophus lanei (Becker, 1949), new combination, Pristilophus sexguttatus (Brown, 1936), new combination, and Pristilophus trivittatus (LeConte, 1853), new combination. Additionally, a global list of species included in Neopristilophus is provided which also corrects generic placements of species included in the genus in the 2001 Ctenicerini world species catalog which were moved to other genera. The original combination for the type species of Agnostelater Costa, 1975 is Pristilophus mesochrous Germar, 1843. A key to species of North American Pristilophus and species list are also provided. Historic concepts of both genera are discussed.
