In Thailand , it occurs above 1300 m in the hill evergreen forest where Fagaceae are dominant, and has been collected from ‘chestnut’ (probably Castanopsis sp. ). The habits of the species have not been described, but as a member of the subtribe Corthylina , it is most probably an ambrosia beetle ( Wood 2007 ).
