Distribution

Paleotropics and Oceania

Gallery system

Consists of a system of irregularly branched tunnels without brood chambers, lying more or less in one transverse plane. When the host tree has thick bark, transverse surface galleries may also be made between the bark and wood (Beeson 1930Beeson 1930:
