Plocamus echidna (LeConte, 1876), new to Quebec

Species identification confirmed by RSA, 2016

Note.

This remarkable native species was previously known in Canada only from Ontario (Bousquet et al. 2013). The circumstances under which all specimens caught in 2016 were found closely match the description provided by Drury (quoted by Blatchley and Leng 1916): "This curious little porcupine beetle was in clusters on trunk of a dead beech tree, near Cincinnati, Sept. 27, 1900. I took one cluster of 30; they very closely resemble the color of the bark". A photograph of the 2015 specimen reported herein is posted on bugguide.net (http://bugguide.net/node/view/1078735/bgimage).
