Phloeotribus dentifrons (Blackman, 1921), new to Quebec

Species identification confirmed by Hume Douglas, 2016

Note.

This minute native species (1.2-1.6mm) was previously known to occur in Canada only in the southernmost part of Ontario (all 61 CNCI Canadian specimens are from Point Pelee National Park). As for the above-mentioned Conotrachelus buchanani , this native species is associated with Celtis spp. ( Wood 1982), specifically common hackberry, Celtis occidentalis , in Quebec. It is probably more widely distributed than currently known in Quebec, as it was found in close association with its host plant in three different localities. It has also been reared recently (2016) from dead branches of Celtis occidentalis in Almonte, Ontario, ca. 30 km from the Quebec border (Hume Douglas, pers. comm. 2017).
