A distributional synopsis of the Pentatomidae (Heteroptera) north of Mexico, including new state and provincial records Author Rider, David A. 0000-0002-1989-1873 david.rider@ndsu.edu Author Swanson, Daniel R. 0000-0002-1989-1873 david.rider@ndsu.edu text Zootaxa 2021 2021-08-03 5015 1 1 69 http://dx.doi.org/10.11646/zootaxa.5015.1.1 journal article 10.11646/zootaxa.5015.1.1 1175-5326 5159085 7FCE5D20-ACC8-41A5-A50D-697D2A686517 Brochymena parva Ruckes, 1946a Distribution: Canada : United States : AZ, CA, CO, NV, NM, TX, UT ( Uhler 1893 , Van Duzee 1917 , Torre- Bueno 1939a, Knowlton & Harmston 1940 , Larivière 1992 ). ( Mexico ) Comments: This species was originally known under the combination Halys obscura Herrich-Schäffer. Unfortunately , this is a preoccupied name for which Ruckes (1946a) provided the above replacement name. Accordingly, most of the early records for this species are under Brochymena obscura . Ruckes (1946a , 1947 ) clarified the status of this species, subsequently confirmed by Larivière (1992) . Essentially, all (or nearly all) records of Brochymena tenebrosa Walker from northern Mexico and from the southwestern United States should be referred to this species.
