Trichodesma beyeri Fall 1905: 174 Figures 3–6 A small number of specimens were seen by Fall from “ Santa Rosa, Lower California ”, with no holotype specified. In the MCZC there are three specimens with that data, one of those specimens labeled as type, but it is unclear as to when this label was added. In accordance with ICZN Recommendation 73F to not assume types, I am designating here one of the other two, a male, as lectotype with the following labels “ Santa Rosa / Low, Cal. // H.C. Fall / Collection // MCZ-ENT [QR code] 00732367 // [on red] LECTOTYPE / Trichodesma beyeri / Fall Designated by / Schnepp, 2023 ”; deposited in the MCZC.
