Anthidium (Anthidium) tenuiflorae Cockerell 1907 (New state record and new for Eastern USA)

( Fig. 17A )

County records: Keweenaw (Isle Royale).

Notes. Gonzalez & Griswold (2013) report this primarily western species from as far east as Minnesota in the US and Saskatchewan in Canada. The Minnesota records are from near Basswood Lake , which is less than 200 km west of Isle Royale, Michigan where the bee was collected in 1957 and also recently by S. Wilson (pers. comm.). A single bee from Manitoba has been examined from Garson Quarry Station , 1 July 1996 (JBWM) suggesting that it should also occur in western Ontario, Canada. Notes on the nest were made by Hicks (1926) in Colorado.

Material examined. Keweenaw Co.: Isle Royale, 3 Jul. 1957, R.W. Hodges (1 ♀ MSUC) ; Isle Royale , 13 Jul. 1957, R.W. Hodges (1 ♀ MSUC) ; Isle Royale , 27 Jul. 1957, R.W. Hodges (1 ♀ MSUC) .
