Buchananius striatus (LeConte, 1876), new to Canada View in CoL

Species identification confirmed by RSA, 2015

Note.

This minute native species (1.4-1.6mm) is easily distinguished from all other Baridinae occurring in Quebec by its extremely wide and convex shape, its tiny size (genus Buchananius Kissinger, 1957, contains the smallest members of Nearctic Baridinae) and its vestiture of sparse but long erect scales. The only other North American congener, Buchananius sulcatus (LeConte, 1876), has been recorded as developing in the fruiting bodies of the fungus Trichoderma peltatum (Berk.) Samuels, Jaklitsch & Voglmayr ( Hypocreaceae ) growing on American Beech, Fagus grandifolia Ehrh. ( Fagaceae ), in Maryland ( Prena et al. 2014). This species also represents a new record at the generic level for Canada.
