13 spp. in our area(1), perhaps close to 200 total
our spp. 2.1-7.5 mm(2) (in the Old World some are much bigger)
key to spp. in(2)
worldwide but poorly represented in the New World; in our area, 2 spp. transcontinental, 4 occur in the east and 7 in the west, esp. sw. US(2)
Closely associated with bark beetles(1)
Fungi, frass, sometimes bark beetle larvae(1)
By the time tree bark loosens enough to be pulled off readily, exposing the old bark beetle tunnels, the Corticeus are already gone -- the reason why they are rarely collected(2)
