New record of a wood-boring isopod, Sphaeroma terebrans (Crustacea: Sphaeromatidae) from Sungai Brunei estuary, Brunei Darussalam

The wood boring isopod, Sphaeroma terebrans is reported for the first time from Brunei coastal waters. The species was found inhabiting fallen wood, jetty piles, wooden poles of water villages and mangrove trees along the Brunei River estuary. Threats to the integrity of such structures and plants through the boring activities of this isopod have the potential for major economic and social impact in Brunei.
