Type locality: Vancouver Island, British Columbia (inferred from title of the paper), herein restricted to Tofino (see Lindroth 1961a: 173). Holotype [by monotypy] (♀) in MCZ [# 5854]. Etymology. The specific name was proposed for Henry and Joseph Matthews, brothers of the British Coleopterist Reverend Andrew Matthews [1815-1897] who specialized in small beetles. Henry and Joseph Matthews collected in British Columbia, including Vancouver Island. Note. There is a clear evidence of an inadvertent error in the original publication of the name matthewsii. It should have been spelled matthewsiorumsince the species was proposed for two men together (see ICZN 1999: Article 31.1.2). However, the spelling matthewsiihas been in used since LeConte proposed the name and I believe it should be preserved. The case should be submitted to the Commission for a ruling.  Zacotus angustusCasey, 1920: 290. Type locality: "Josephine Co[unty], Oregon" (original citation).
