Debus emarginatus
Beaver and Browne, 1978: The species often makes surface galleries and brood chambers between bark and wood, in addition to deeper galleries. It will bore into newly sawn timber. Browne, 1961: This rather variable shothole borer of moderate size has a wide distribution is Malaysia. It is most attracted to the families Dipterocarpaceae and Leguminosae. The species is most commonly found in large logs but will infest stems down to a diameter of about 15 cm and occasionally even smaller material. It attacks unhealthy, dead or recently cut trees and has also been found boring in newly sawn unseasoned timber. A transverse surface gallery between bark and wood is created associated with a surface brood chamber in which the larger part of the young brood live. Other tunnels branch off at right angles from the surface gallery and penetrate directly into the wood where they may have a secondary branch gallery with more brood chambers in the longitudinal plane. Hulcr and Cognato, 2012: Galleries with several irregular brood chambers. Significant portion of tunnel system between bark and xylem core. Galleries (tunnels and chambers) often between bark and xylem (Beaver & Browne 1978). India to New Guinea, from sea level to over 2100m a.s.l., common throughout its range.
