Non-native beetle found in Chile?

P. recurva indeed, you can tell by the inwardly 'curved' spines on the second antennal segment.
Another species which has simple spines and is somewhat darker, has also become a serious pest of Eucalyptus spp. is the closely related P. semipunctata.
In Australia both species tend to attack recently dead and dying trees only, whereas reports from other countries suggest infestation upon healthy trees.
