Coptodryas confusa Hopkins, 1915a: 54.
Xyleborus cryphaloides Schedl, 1942a: 191. Wood and Bright, 1992: 823.
1.8−2.2 mm long (mean = 2.18 mm; n = 5); 2.0−2.25 times as long as wide. This species can be identified from all other species in the region by its unique mycangia that includes both typical elytral mycangia with conspicuous medial tufts of setae and a pair of pit mycangia located near the pronotal base. In addition, the protibia has an evenly rounded outer margin; elytral strial and interstrial punctures confused; interstriae tuberculate; elytra setose; pronotum tall (type 2) when laterally viewed; and pronotum anterior margin unarmed by a row of serrations.

apparently highly host-selective, and recorded only from trees of the family Dipterocarpaceae (Browne 1961b, Wood and Bright 1992).
Browne (1961b) notes that the species attacks trees of any size down to about 5 cm diameter, and has been known to attack newly sawn, unseasoned boards in a sawmill.
