November 2005. A beetle from Guam, found boring into the dead heartwood of a twig from mango.

It was identified as a Tenebrionid, but it is difficult to identify it further as the type specimens of most species are at the Bishop Museum, Honolulu. It may be Tribe Amarygmini. These beetles are likely to be secondary invaders into already damaged wood and, therefore, not true “borers”. They tend to feed on fungi in the wood.

In Singapore, Terebrionids do not bore into sapwood of mango; Cerembycids, like Rhytidodera usually attack the branches and twigs.

A Tenebrionid from Acacia and Eucalyptus wood chip was also reported as an interception in China (Hainan Yangpu Entry-Exit Inspection and Quarantine Bureau, The People’s Republic of China).
